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...

Abstract: Compact stars, such as neutron stars or white dwarfs, often collide with bigger, non-degenerate stars. In this interaction, the NS captures copious amounts of matter that flows inwards. The density of the gas in this scenario is so high...

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...

Early results of JWST observation have revealed an unexpected abundance of red compact objects dubbed little red dots (LRDs) at z>4. These objects display a faint blue rest-frame UV continuum followed by a steep red rise in the rest-frame optical...
