Speaker: Chirag Modi – University of California, Berkeley

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.

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 […]

INPA Seminar – Harikrishnan Ramani (LBNL)

50A-5132- Sessler 50A-5132 Sessler Conference Room, CA

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. […]

Speaker: Vishal Gajjar (UC Berkeley)

50A-5132- Sessler 50A-5132 Sessler Conference Room, CA

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? […]

50A-5132- Sessler 50A-5132 Sessler Conference Room, CA

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 […]
