Title: Reconstruction of Cosmological Fields in Forward Model Framework - Galaxy Clustering and Intensity Mapping Abstract: In this talk, I will outline the forward model approach to reconstruct cosmological fields in a Bayesian framework. I will focus on two examples - galaxy clustering and neutral hydrogen intensity mapping. In galaxy clustering example, I will use […]

Title: Cosmology with the Lya forest: beyond two-point statistics, DESI instrumentation Abstract: The Lyman-alpha forest is currently the only probe of cosmology and the state of the intergalactic medium (IGM) between redshifts of z=2 and 6. It's higher-order clustering, specifically its three-point correlation function (3PCF), contains information that can help to constrain fluctuations in the […]

Title: Challenges and pathways forward in supernova cosmology Abstract: Using the DES photometric supernova cosmology analysis as groundwork, I will summarise our current analysis methodologies, from simulations, to transient classification, selection effect treatment, and cosmology. Despite recent improvements in analysis methods, there still exist fundamental challenges in areas spanning the initial empirical SN Ia model […]

Title: The extended Baryon Oscillation Spectroscopic Survey: clustering measurements, lessons, and prospects Abstract: In this talk, I will present the clustering analysis of the ELG (Emission Line Galaxy) sample from the eBOSS (extended Baryon Oscillation Spectroscopic Survey) program of the Sloan Digital Sky Survey and review the other clustering analyses of the eBOSS program, dedicated […]

Title: Clustering measurements in the final eBOSS quasar sample and their cosmological implications Abstract:In this talk I present the clustering analysis of the final extended Baryon Oscillation Spectroscopic Survey (eBOSS) quasar sample at redshift 0.8<z<2.2, which bridges the redshift gap between the eBOSS LRG and Lyman-alpha measurements. Mapping the evolution of the expansion and growth […]

Title: Full analysis of the background for the search of neutrinoless double beta decay in Gerda Abstract: The GERmanium Detector Array (Gerda) experiment aims for the discovery of neutrinoless double beta decay (0νββ) decay in 76Ge. It uses HPGe detectors enriched in the isotope 76Ge, which are directly immersed into liquid argon (LAr). In second […]

Speaker: Karthik Ramanathan (University of Chicago)   Title: Dark Matter Taking Selfies: The DAMIC Experiment  Abstract: The DAMIC (Dark Matter in CCDs) experiment uses silicon charge-coupled devices (CCDs), traditionally employed for imaging purposes, to detect potential ionization signals from dark matter interactions. These approx. mm thick devices feature an impressively low leakage current (< 10-21 A/cm2) and […]

Speaker: Harikrishnan Ramani (LBNL)   Title: Nuclear Isomers as Dark Matter accelerators Abstract: Weak-scale dark matter particles, in collisions with nuclei, can mediate transitions between different nuclear energy levels. In particular, owing to sizeable momentum exchange, dark matter particles can enable de-excitation of nuclear isomers that are extremely long lived with respect to regular radioactive decays. […]

Title: Breakthrough Listen's search for intelligent life in the Universe  Abstract: The discovery of the ubiquity of habitable extrasolar planets, combined with revolutionary advances in instrumentation and observational capabilities, have ushered in a renaissance in the millennia-old quest to answer our most profound question about the Universe and our place within it - Are we alone? […]

Speaker: Wouter Van De Pontseele (Harvard/Oxford)   Title: The MicroBooNE Neutrino Experiment at Fermilab Abstract: MicroBooNE is a liquid argon time projection chamber in the Booster Neutrino Beam at Fermilab. The technology provides high-resolution imaging of neutrino interactions leading to low-threshold event reconstruction with full angular coverage. As such, this is an ideal place to probe […]

Speaker: Chiara Capelli (University of Zurich) Title: Data analysis at high-energies for the XENON1T experiment and light calibration system of XENONn  Abstract: The XENON1T experiment searches for Weakly Interacting Massive Particles (WIMPs) with a dual-phase xenon Time Projection Chamber (TPC). To extend its physics reach, the efforts of the XENON collaboration are directed toward exploring other […]

Speaker: Gulden Othman (University of North Carolina) Title: CAGE Scanner: Investigating Surface Backgrounds in HPGe Detectors for Neutrinoless Double-Beta Decay Searches Abstract: A potential source of problematic backgrounds in a ton-scale 76Ge-based neutrinoless double-beta decay (0nuBB) program may arise from particle interactions occurring near the surfaces of high purity germanium (HPGe) detectors. The Collimated Alphas, Gammas, […]

  Speaker: Rebecca Carney (SLAC)   Title: Silicon tracking in the search for rare processes    Abstract: The ATLAS Detector, below the surface of the Swiss-French border, measures the remnants of high-energy proton-proton collisions, accelerated by the Large Hadron Collider (LHC) at CERN. A little over a year ago the LHC paused operations, having delivered an integrated luminosity […]

Speaker: Zara Bagdasarian (UC Berkeley) Title: Borexino. Sun. Earth. Neutrinos Abstract: Borexino experiment is a 280-ton liquid scintillator detector located at a 3800 m w.e. depth in the Laboratori Nazionali del Gran Sasso (Italy). In more than 12 years of data taking, Borexino has demonstrated how its unprecedented radio-purity led to exploring a wide range […]

Speaker: Nicholas Rodd (LBNL)   Title: Evidence the 3.5 keV line is not from dark matter decay Abstract: X-ray observations of nearby clusters and galaxies have reported an unexpected X-ray line around 3.5 keV. This line has received significant attention due to its possible explanation through decaying dark matter; in particular, decaying sterile neutrino models, […]
