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...

Fast radio bursts (FRBs) are a recently discovered, poorly understood class of transient event, and understanding their origin has become a central problem in astrophysics. I will present FRB science results from CHIME, a new interferometric...

The Sun hosts a wide range of explosive phenomena, from small brightenings and jets to large solar flares and coronal mass ejections. Thanks to their proximity, these events can be studied with exceptionally high spatial, temporal, and spectral...

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

Based on latest state of the art general relativistic magnetohydrodynamic simulations, I will discuss how black holes feast on the surrounding gas, burp away their surroundings, and produce bright emission in a wide range of contexts, ranging from...

Over the past two decades, cosmological spectroscopic and photometric surveys have substantially advanced our understanding of galaxy formation and cosmology. Nevertheless, these two types of surveys possess unique advantages and disadvantages...
