SUMMARY:VIRTUAL INPA SEMINAR | Matthew Ho (Carnegie Mellon)
DESCRIPTION:Speaker: Matthew Ho (Carnegie Mellon) \nTitle: Galaxy Cluster Mass Estimation Using Deep Learning  \nAbstract: \nIn this talk\, I will discuss how we use modern deep learning models to infer galaxy cluster masses with high precision\, reliable uncertainty\, and computational efficiency. I will describe our work in using Convolutional Neural Networks (CNNs) to mitigate systematics in the virial scaling relation to produce dynamical mass estimates of galaxy clusters\, using projected galaxies\, with remarkably low bias and scatter. I will also discuss how we can recover and empirically verify Bayesian uncertainties on deep learning mass predictions using variational weight distributions. I will describe how we’ve validated our methods on real observational systems like the Coma\, CLASH\, and HeCS clusters as well as projections for how we can use these models to study cluster cosmology using data from current and upcoming sky surveys. Lastly\, I will mention results from our ongoing work on combining multi-wavelength observables to produce fully informed observational probes of cluster dark matter.\n\n\n\n\n\n\n\n\n\nJoin Zoom Meeting\n\nhttps://lbnl.zoom.us/j/93651647483 \nMeeting ID: 936 5164 7483

SUMMARY:VIRTUAL INPA SEMINAR | Jason Sun (CalTech )
DESCRIPTION:Speaker: Jason Sun (CalTech) \nTitle: Understanding the Cosmological Evolution of Galaxies with Intensity Mapping  \nAbstract: \nThe intensity mapping (IM) technique has been devised as a powerful tool to investigate the formation/evolution of the large scale structure and galaxies\, alternative and complementary to the more traditional means relying on galaxy detection. In the high-redshift universe\, in particular\, synergies of multiple IM tracers have been widely perceived as a promising way of revealing the connection between the emergence of first stars and galaxies and the reionization\, a still mysterious chapter of cosmic history that even the JWST might not fully elucidate. I will present two main themes of my research on applications of the IM technique to understand the cosmological evolution of galaxies. On the experimental side\, I will introduce the analysis and forecasting work I led for the Tomographic Ionized-carbon Mapping Experiment (TIME). TIME is a novel imaging spectrometer array recently commissioned that pioneers the quest for measuring large-scale intensity fluctuations of the 158-micron [CII] line emission redshifted from the epoch of reionization\, which serves an ideal probe of ongoing cosmic star formation that sources the hydrogen-ionizing radiation background. I will discuss how TIME\, with an optimization of survey strategy\, can inform us about the reionization on its own and through synergies with other probes like galaxy surveys. I will also discuss challenges and opportunities arising from low-redshift “line interlopers”\, namely rotational CO lines at z ≈ 0.5 to 2 for TIME\, which require some exquisite cleaning strategy to be removed but at the same time allow a census of the molecular gas content of galaxies near the “cosmic high noon”. On the theory side\, I will introduce LIMFAST\, a fast\, semi-numerical simulation developed to physically and self-consistently simulate a large set of high-redshift line-intensity mapping (LIM) data in different frequency regimes\, including tracers of neutral gas (e.g.\, HI 21cm) and star-forming galaxies (e.g.\, Lyα\, [CII]). I will elaborate on the scientific applications of LIMFAST to simulate multi-tracer LIM observations of high-redshift galaxies and their interplay with the intergalactic medium during reionization. Particular emphases will be on (1) how various LIM signals\, such as Hα\, Lyα and [CII]\, and their cross-correlations with the HI 21cm signal\, may be affected by the astrophysics governing galaxy formation\, such as feedback and star formation laws; and (2) how these astrophysical processes may be studied with future LIM experiments to deepen our understanding of high-redshift galaxy populations from both observational and theoretical perspectives. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98739327626\nMeeting ID: 987 3932 7626

SUMMARY:VIRTUAL INPA SEMINAR | Chiara Salemi (MIT)
DESCRIPTION:Location: via Zoom \nSpeaker: Chiara Salemi (Massachusettes Institute of Technology) \nTitle: Seeing the Invisible: Search for Low-Mass Axion Dark Matter \nAbstract: \nMultiple astrophysical and cosmological observations have shown that the visible matter described by the Standard Model is only a small fraction of the energy in the universe. We believe that there is about five times as much dark matter\, which is likely comprised of massive particles that interact very little or not at all with other matter. One of the most well-motivated candidates to be the dark matter is the axion\, a hypothetical particle that is predicted by the solution to another long-standing mystery in physics\, the strong CP problem. This talk presents ABRACADABRA-10 cm\, the first direct search for low-mass axion dark matter\, which used an innovative lumped element detection method. This prototype experiment set world-leading limits on axions and set the stage for the DOE-funded DMRadio program\, a series of larger detectors that will be capable of finding axions or definitively excluding them over a large range of masses below 1 μeV. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/93849799393 \nMeeting ID: 938 4979 9393

SUMMARY:VIRTUAL INPA SEMINAR | Phillipp Windischofer (University of Oxford)
DESCRIPTION:Location: via Zoom \nSpeaker: Phillipp Windischofer (University of Oxford) \nTitle: Detectors for Physics and Physics For Detectors \nAbstract: \nPowerful instrumentation has been a key enabler for many discoveries at the forefront of fundamental physics\, from gravitational waves to the Higgs boson. In this seminar\, I will argue that the converse is also true. I will show that applying established tools from physics to the study of particle detectors is a compelling strategy for identifying synergies and moving beyond the current boundaries of our instrumentation.\n \nStarting from classical electrodynamics\, I will explain how reciprocity relations give rise to a rigorous description of the electrical signals induced in detectors by moving charged particles\, and how this opens up new possibilities for the simulation of radio arrays for neutrino detection. Continuing with many-body quantum mechanics\, I will then highlight how Fock-space methods can be used to characterise the time resolution of single-photon avalanche diodes (SPADs). Taken together\, these calculations suggest that SPADs can also act as fast detectors for charged particles\, and I will end by presenting the first results from a recent beam test at the CERN SPS that demonstrate this capability.\n \nJoin Zoom Meeting\n https://lbnl.zoom.us/j/93457647521 \nMeeting ID: 934 5764 7521

SUMMARY:VIRTUAL INPA SEMINAR |Charlotte Alison Ward (Univ. of Maryland at College Park)
DESCRIPTION:Speaker: Charlotte Alison Ward (Univ. of Maryland at College Park) \nTitle: Using The Zwicky Transient Facility and Vera C. Rubin Observatory To Study Black Hole Seeds\, Discover High-Z Quasars\, and Measure Time Delays From Lensed Supernovae \nAbstract: \nOver the last 3 years\, the Zwicky Transient Facility (ZTF) has demonstrated the potential of wide-field transient surveys for the discovery of black hole populations which trace the formation of the first BH seeds and their merger-driven growth. For instance\, our search for off-nuclear AGN in ZTF revealed 9 supermassive black holes (SMBHs) which may have been ejected from their host galaxy by gravitational wave recoil from SMBH mergers with misaligned spins. Likewise\, our search for faintly variable intermediate mass black holes (IMBHs) in dwarf galaxies with ZTF and WISE found 200 new IMBH candidates\, most of which could not have been found via their spectroscopic or multi-wavelength signatures. We found these rare BH populations by using the latest techniques in forward modeling to improve photometric sensitivity\, resolve blended sources and measure the separations between variable objects and their host galaxies. Our work is an exciting precursor to the Legacy Survey of Space and Time (LSST)\, which we expect to detect large populations of recoiling SMBHs\, IMBH candidates\, and high-z quasars—especially when combined with large spectroscopic surveys. LSST is also predicted to find thousands of strongly gravitationally lensed\, multiply-imaged supernovae\, and application of the forward modeling techniques we previously demonstrated for ZTF will enable improved measurements of the Hubble constant. \n\n\n\nJoin Zoom Meeting https://lbnl.zoom.us/j/98918084629?pwd=TkNBeDhkZHZ0bmkzdTA0aUJ5VlFsdz09 Meeting ID: 989 1808 4629 \nPasscode: 173713

SUMMARY:VIRTUAL INPA SEMINAR | Luca Pagani (UC Davis )
DESCRIPTION:Speaker: Luca Pagani (UC Davis) \nTitle: First Results From The ARTIE Experiment \nAbstract: \nA measurement of the transmission coefficient for neutrons through a thick (~3 atoms/b) liquid natural argon target in the energy range 30-70 keV was performed by the Argon Resonance Transmission Interaction Experiment (ARTIE) using a time of flight neutron beam at Los Alamos National Laboratory. In this energy range theory predicts an anti-resonance in the 40-Ar cross section near 57 keV\, but the existing data\, coming from an experiment performed in the 90s (Winters. et al.)\, does not support this. This discrepancy gives rise to significant uncertainty in the penetration depth of neutrons through liquid argon\, an important parameter for next generation neutrino and dark matter experiments.In this talk\, the first results from the ARTIE experiment will be presented. The ARTIE measurement of the total cross section as a function of energy confirms the existence of the anti-resonance near 57 keV\, but not as deep as the theory prediction. \n\n\n\nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/96839979915pwd=VXIvTVFiSDN4cHdFYJTb0hiTUhWUT09 \nMeeting ID: 968 3997 9915 \nPasscode: 273612

SUMMARY:VIRTUAL INPA SEMINAR | Noah Kurinsky (SLAC )
DESCRIPTION:Speaker: Noah Kurinsky (SLAC) \nTitle: Quantum Sensors for Direct Detection of Sub-GeV Dark Matter  \nAbstract: \nOver the last 20 years\, searches for dark matter above the proton mass have advanced significantly across direct and indirect searches\, but sub-GeV dark matter has until recently been comparatively unprobed. In this talk\, I will discuss the state of the Sub-GeV direct detection field\, and prospects for applying quantum measurement techniques to lowering mass thresholds for new searches with event thresholds at the eV-scale. I will then discuss the outlook for the field in the next 5-10 years\, in the context of synergy with ongoing research in materials science and quantum information science. The goal over the next decade is to run background-free dark matter searches at gram-year exposures with meV-scale thresholds\, an exciting challenge that requires a broad range of expertise\, and comes with enormous scientific discovery potential. \n\n\nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/98007893520?pwd=SzBwWkkxalhDOVVCcUNLRTdONEhNZz09 \nMeeting ID: 980 0789 3520 \nPasscode: 334893

SUMMARY:VIRTUAL INPA SEMINAR | Peter Taylor (NASA Jet Propulsion Laboratory )
DESCRIPTION:Speaker: Peter Taylor (NASA Jet Propulsion Laboratory ) \nTitle: The RSD Sorting Hat  \nAbstract: \nRedshift-space distortions (RSD) and weak lensing (WL) studies yield some of the tightest cosmological constraints. Large overlapping data sets from Euclid\, the Rubin Observatory\, the Roman Space Science Telescope and the Dark Energy Spectroscopic Instruments will enable a joint RSD/WL analysis. Such an analysis could significantly outperform WL and RSD analyses performed in isolation. In this talk I show how to optimally extract information from the RSD signal using angular statistics. This is a first step towards combing WL and RSD. \n\n\nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/91769253333?pwd=dVZwcHFLVjJLMXBYaWRWaU5VK0p5dz09 \nMeeting ID: 917 6925 3333 \nPasscode: 638637

SUMMARY:VIRTUAL INPA SEMINAR | Kevin Thieme (Univ. of Zurich)
DESCRIPTION:Speaker: Kevin Thieme (University of Zurich) \nTitle: A Measurement of the Mean Electronic Excitation Energy of Liquid Xenon \n\n\nAbstract: \nDetectors using liquid xenon as target are widely deployed in rare event searches. Conclusions on the interacting particle rely on a precise reconstruction of the deposited energy which requires calibrations of the energy scale of the detector by means of radioactive sources. However\, a microscopic calibration\, i.e. the translation from the number of excitation quanta into deposited energy\, also necessitates good knowledge of the energy required to produce single scintillation photons or ionisation electrons in liquid xenon. The sum of these excitation quanta is directly proportional to the deposited energy in the target. The proportionality constant is the mean excitation energy and is commonly known as W-value. Here we present a measurement of the W-value with electronic recoil interactions in a small dual-phase xenon time projection chamber with a hybrid (photomultiplier tube and silicon photomultipliers) photosensor configuration. Our result is based on calibrations at O(1–10 keV) with internal 37-Ar and 83m-Kr sources and single electron events. We obtain a value of W=(11.5 +0.2 -0.3 (syst.)) eV\, with negligible statistical uncertainty\, which is lower than previously measured at these energies. If further confirmed\, our result will be relevant for modelling the absolute response of liquid xenon detectors to particle interactions. \n\nJoin Zoom Meeting https://lbnl.zoom.us/j/93376704948?pwd=ZnJsMzhOcmFqc1hnWTZZbmEzeHhSZz09  \nMeeting ID: 933 7670 4948  \nPasscode: 373301

SUMMARY:VIRTUAL INPA SEMINAR | Andreas Biekert (UC Berkeley)
DESCRIPTION:Speaker: Andreas Biekert (UC Berkeley) \nTitle: Scintillation Yield From Electronic and Nuclear Recoils In Superfluid 4He  \nAbstract: \nHeRALD is a proposed sub-GeV scale dark matter detector based on a superfluid 4He target and transition edge sensor readout\, supported as part of the TESSERACT project. Possible signal channels available for readout include prompt photons\, triplet excimers\, and roton and phonon quasiparticles\, but the relative strength of these signals for low energy nuclear recoils requires experimental verification. We have measured the superfluid 4He scintillation yield at 1.75 K from nuclear recoils in the range of 50-1100 keV using a 16 cm3 target volume read out by six superfluid-immersed PMTs. Elastic scattering of 2.8 MeV neutrons produced by a deuterium-deuterium neutron generator and Compton scattering of 662 keV 137Cs gamma rays were used to determine the relative scintillation yield. Yields of both prompt and delayed scintillation components were measured and compared to a semi-empirical response model based on helium-helium and electron-helium scattering cross sections. We also discuss the development of a 24 keV neutron source to extend our measurements to smaller nuclear recoil energies. \nJoin Zoom Meeting https://lbnl.zoom.us/j/91625792208?pwd=WGhqZ29TVlQxMHpnVXpqRDJVNXNBZz09 \nMeeting ID: 916 2579 2208  \nPasscode: 793885

SUMMARY:SPECIAL VIRTUAL INPA SEMINAR | Jingkai Xia (Shanghai Tech)
DESCRIPTION:Speaker: Jingkai Xia (Shanghai Tech) \nTitle: Detector Study For New Generation Of Neutrino And Dark Matter Experiments In China \nAbstract: \nNon-zero neutrino mass and the existence of dark matter are two important observations beyond the Standard Model of particle physics. Research on neutrino properties and dark matter detection will help to promote the discovery of new physics. New generation of neutrino and dark matter experiments are under construction or in commissioning in China\, where advanced detectors are the key to meet the scientific goals. In this talk\, I will introduce my work in detector research efforts in JUNO and PandaX-4T experiments\, as well as study on detector technique which may be utilized in future experiments in China.\n \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/96324647091?pwd=bG1JZzJldko4aFBQd2ZLbFR5NnU4Zz09\nMeeting ID: 963 2464 7091\nPasscode: 938213

SUMMARY:VIRTUAL INPA SEMINAR | Alessio Porcelli (Ghent University)
DESCRIPTION:Speaker: Alessio Porcelli (Ghent University) \nTitle: Method To Measure The Cosmic Rays Mass Composition With IceCube/IceTop \nAbstract: \nThere is an intrinsic difficulty in measuring the mass of Cosmic rays at Ultra-High Energy. The only possible way involves measuring the Extensive Air Showers (EAS) characteristics produced by hadronic interactions of the incoming particle (primary) with the atmosphere: it behaves as a calorimeter producing secondary particles. EAS are characterized by a longitudinal profile along the shower development and a lateral one at the ground around the shower core. In the latter distribution\, because of the shower physics\, the information of the mass is delivered by the muon component. \nIceTop is part of the IceCube experiment\, sited at the geographic South Pole. While the latter consists of 86 strings drilled inside the ice covering a kilometer cube to detect neutrinos from astrophysical origins\, the former are stations on the top of such strings used to veto atmospheric neutrinos. IceTop consists of 81 stations\, each with two water Cherenkov detectors with two Photomultiplier Tubes each\, able to detect Cherenkov light produced by the crossing charged particles. This setup of detectors can also be used to measure the EAS lateral distribution\, letting IceCube be able to measure also Cosmic Rays with energies above 1 PeV and up to 1 EeV. \nTwo different approaches will be presented in the seminar\, using IceTop alone or together with the in-ice part of IceCube. Moreover\, improvement attempts will be depicted: analysis strategies and the incoming extension IceCube-Gen2. \n\nJoin Zoom Meeting  \nhttps://lbnl.zoom.us/j/93261885135?pwd=aFlsU1lHMGpHTE5SNlJaNTZENzBlQT09  \nMeeting ID: 932 6188 5135  \nPasscode: 113108

SUMMARY:VIRTUAL INPA SEMINAR | María Martínez (Universidad de Zaragoza)
DESCRIPTION:Speaker: María Martínez ​(​Universidad de Zaragoza​)​ \nLocation: via Zoom \nTitle: Annual ​M​odulation ​R​esults ​F​rom ​Three​ ​–​Y​ear ​E​xposure of ANAIS-112 \nAbstract: \nFor more than 20 years\, the DAMA/LIBRA experiment at the Gran Sasso Underground Laboratory (Italy) has claimed a positive dark matter detection: an annual modulation in the low-energy detection rate compatible with the expected signal induced by dark matter particles due to the Earth rotation around the Sun. This signal is in strong tension with the negative results of other very sensitive experiments. However\, until recently a direct comparison using the same target material (NaI(Tl)) was lacking. ANAIS (annual modulation with NaI Scintillators) is a dark matter direct detection experiment located at the Canfranc Underground \n \nLaboratory (LSC\, Spain). Its main goal is to test in a model independent way the DAMA/LIBRA positive result. ANAIS-112 operates 112.5 kg of NaI(Tl) scintillators at the LSC since August 2017 and is taking data smoothly with excellent performances. Results from the first three years are compatible with the absence of modulation and incompatible with the DAMA/LIBRA measured modulation at more than 2.5 sigma C.L.\n\nIn this seminar I will briefly review the DAMA/LIBRA puzzle and the status of the experiments trying to reproduce it. Then I will introduce the ANAIS-112 experimental set-up\, the detector performance and analysis methods. Finally\, I will present the results of the annual modulation analysis corresponding to three years of ANAIS data\, the physical implications and the prospects for the 5 years of scheduled operation time.\n\n\n\nJoin Zoom Meeting​ \n​https://lbnl.zoom.us/j/95105088780\nMeeting ID: 951 0508 8780

SUMMARY:VIRTUAL INPA SEMINAR | Javier Menéndez (University of Barcelona)
DESCRIPTION:Speaker: Javier Menéndez (University of Barcelona) \nTitle: Nuclear Theory To Reveal The Nature Of Dark Matter And Neutrinos \n\n\n\nLocation: via Zoom \n\n\n\n\nAbstract: \nUnveiling the nature of dark matter is one the most exciting challenges in physics. While it constitutes about a quarter of the energy-density of the universe and 80% of its mass\, the composition of dark matter remains elusive. Beyond the solid evidence based on its gravitational properties\, a key step would be the direct detection in the laboratory\, a program led by searches of the scattering of dark matter particles off atomic nuclei. Naturally\, the interpretation of these experiments depends on the nuclear physics input that describes the dark matter scattering off nuclei. Assuming a scenario where dark matter is mainly composed by WIMPs (weakly interacting massive particles) that couple to quarks and gluons\, I will introduce nuclear theory insights needed to characterize the possible nuclear-WIMP interactions\, with focus on which WIMP-nucleus interactions can receive contributions from several nucleons in the nucleus (coherence)\, or how experiments could distinguish between different WIMP-nucleus interactions. \nLikewise\, the scattering of neutrinos off nuclei and a rare proposed nuclear decay\, neutrinoless double-beta decay\, can determine if neutrinos are its own antiparticles\, and pin down physics beyond the Standard Model. Again\, these processes depend on nuclear physics input that needs to be calculated from nuclear theory and which is key to interpret experimental searches. If time allows\, I will also discuss the most prominent features of the nuclear matrix elements for coherent neutrino-nucleus scattering and neutrinoless double-beta decay. \n\n\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91005179177?pwd=azllWlVkeC85RWpYdGd5YTRGeTF3QT09\nMeeting ID: 910 0517 9177\nPasscode: 256328

SUMMARY:VIRTUAL INPA SEMINAR | Bryan Ramson (Fermilab)
DESCRIPTION:Location: via Zoom \nSpeaker: ​Bryan Ramson (​Fermilab) \nTitle: Towards A New Generation of Bubble Chambers\n \nAbstract: \nLong baseline neutrino oscillation experiments present some of the most compelling paths towards beyond the standard model physics through measurement of PMNS matrix elements and observation of leptonic CP violation. State of the art long baseline oscillation experiments\, like NOvA and T2K\, are currently statistically limited\, however uncertainty in neutrino-nuclei scattering represent leading sources of systematic uncertainty and will fundamentally limit the precision of future experiments like DUNE and T2HK if not addressed. Neutrino cross section uncertainties can be reduced through high statistics measurement of neutrino interactions on light nuclei\, but creating a detector with an appropriate light target has proved elusive since the hydrogen bubble chambers of the previous century. Modern chamber based dark matter detectors like PICO/PICASSO/COUPP and the Scintillating Bubble Chamber have demonstrated that advances in sensor technology\, computing\, and automation would allow a modern bubble chamber to fully utilize the megawatt scale intensity LBNF beam through the use of high resolution and high speed cameras\, novel triggering\, and machine-learning based event reconstruction. This talk will review the broad physics program for the construction of a bubble chamber for use with neutrinos supplied by the LBNF. \n\nJoin Zoom Meeting https://lbnl.zoom.us/j/92148547097?pwd=UFp3THQ2U05TeUJiL3dwNVBIbHB1UT09 \nMeeting ID: 921 4854 7097 \nPasscode: 100306
