After ten years of gravitational-wave observations with the LIGO–Virgo–KAGRA interferometers, over 200 signals from merging black hole binaries have been detected, bringing us closer to understanding how these systems form. Addressing this question...

The structure of dark halos carries signatures of their mass, dynamical state, and the nature of dark matter itself. Some of the most constraining signals can be found in the outskirts of galaxy clusters, which have recently become observationally...

The Bahcall Lunch follow the astrophysics colloquium lecture. Registration is required by noon the previous Thursday so a meal can be provided.

The hot, diffuse intracluster medium (ICM) permeates the deep gravitational potential wells of galaxy clusters and serves as a window inside these massive, dark matter dominated structures. Radiating primarily at X-ray wavelengths, the ICM encodes...

Over the last decade, large optical time-domain surveys have systematized the discovery of transient flares of emission associated with the tidal disruptions of stars by supermassive black holes. These tidal disruption events (TDEs) are rare events...

Abstract: Fractionalization of the electron charge is one of the most striking phenomena arising from strong electron-electron interactions. A celebrated example is the emergence of anyons with fractionally charged excitations in fractional quantum...
