Institute for Nuclear and Particle Astrophysics (INPA) at LBNL

The INPA Seminar weekly talks are on Fridays, starting at 12:00 pm, unless informed otherwise. The seminar talk starts with a brief presentation of the weekly scientific news. Typically, the talks conclude by 1:00 pm. The seminars are held in the Sessler Conference Room,  located in Bldg. 50A- 5132.

The committee members are:

The seminar schedule for the Institute for Nuclear and Particle Astrophysics (INPA) is tentative and becomes final a few days before the Friday talk.

Please send all suggestions for future INPA talks and speakers to the INPA Committee.

VIRTUAL INPA SEMINAR | Andreas Biekert (UC Berkeley)

Speaker: Andreas Biekert (UC Berkeley) Title: Scintillation Yield From Electronic and Nuclear Recoils In Superfluid 4He  Abstract: HeRALD 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 […]

VIRTUAL INPA SEMINAR | Kevin Thieme (Univ. of Zurich)

Speaker: Kevin Thieme (University of Zurich) Title: A Measurement of the Mean Electronic Excitation Energy of Liquid Xenon Abstract: Detectors 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 […]

VIRTUAL INPA SEMINAR | Peter Taylor (NASA Jet Propulsion Laboratory )

Speaker: Peter Taylor (NASA Jet Propulsion Laboratory ) Title: The RSD Sorting Hat  Abstract: Redshift-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 […]


Speaker: Noah Kurinsky (SLAC) Title: Quantum Sensors for Direct Detection of Sub-GeV Dark Matter  Abstract: Over 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 […]

VIRTUAL INPA SEMINAR | Luca Pagani (UC Davis )

Speaker: Luca Pagani (UC Davis) Title: First Results From The ARTIE Experiment Abstract: A 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 […]

VIRTUAL INPA SEMINAR |Charlotte Alison Ward (Univ. of Maryland at College Park)

Speaker: Charlotte Alison Ward (Univ. of Maryland at College Park) Title: 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 Abstract: Over the last 3 years, the Zwicky Transient Facility (ZTF) has demonstrated the potential of wide-field transient surveys for […]

VIRTUAL INPA SEMINAR | Phillipp Windischofer (University of Oxford)

Location: via Zoom Speaker: Phillipp Windischofer (University of Oxford) Title: Detectors for Physics and Physics For Detectors Abstract: Powerful 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 […]


Location: via Zoom Speaker: Chiara Salemi (Massachusettes Institute of Technology) Title: Seeing the Invisible: Search for Low-Mass Axion Dark Matter Abstract: Multiple 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 […]


Speaker: Jason Sun (CalTech) Title: Understanding the Cosmological Evolution of Galaxies with Intensity Mapping  Abstract: The 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 […]

VIRTUAL INPA SEMINAR | Matthew Ho (Carnegie Mellon)

Speaker: Matthew Ho (Carnegie Mellon) Title: Galaxy Cluster Mass Estimation Using Deep Learning  Abstract: In 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 […]

INPA guests from campus can now come to the lab early on Fridays. The INPA Common Room (50-5026) is reserved for our guests from 10:00 a.m. to 12:00 noon and from 1 p.m. to 5 p.m. Note that the seminars are now held in 50A-5132 to accommodate a more significant number of attendees.
