Astrophysics

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

The astronomer Carl Sagan once said “We are made of stardust.” What exactly did he mean? And how, in fact, did we come to be in the Universe? Today, we will take a journey from the Big Bang to the present to answer these questions. Of course, many...

Abstract: There has been exciting recent progress in the study of the quantum nature of black holes through the use of certain exactly solvable models. This work shows how to realize, in concrete terms, various long-held expectations about quantum...

Tidal disruption events (TDEs) provide an exciting opportunity to study supermassive black holes (SMBHs) in quiescent galaxies and the stellar populations and dynamics in galactic nuclei. They test the limits of black hole accretion by regularly...

Abstract: Organic scintillators are a promising avenue for the direct detection of sub-GeV dark matter (DM). With eV-scale excitation energies that rival the sensitivity of semiconductor targets, they can be produced in bulk and purified relatively...
