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

Strong gravitational lenses have provided great insights into the expansion history of the universe and the dark matter distribution from clusters down to sub-galactic scales. Current state-of-the-art measurements involving strong gravitational...

The GRAVITY experiment at the Very Large Telescope Interferometer (VLTI) has fundamentally redefined the landscape of high-angular-resolution astronomy. By delivering routine milli-arcsecond imaging, a thousandfold increase in sensitivity, and micro...

Abstract: When a compact object collapses to form a black hole, quantum field theory predicts the emission of an energy outflux to future null infinity, which later relaxes to Hawking radiation. Within the semiclassical framework, we derive a simple...

Abstract: The extreme-density environments inside neutron stars provide a unique natural testbed for probing nuclear physics. In the first part of this talk, I will explain how gamma-ray burst observations can be used to extract information about...

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...
