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 ubiquity of substructures in protoplanetary discs has opened debate regarding the alignment of planet formation timescales with protostellar disc evolution. Under the hypothesis of the planetary interpretation, a robust conclusion is that a...

 A revolution is underway in our understanding of the origins of supermassive black holes (SMBHs), reshaping our view of how the very first black holes formed and grew in the early universe. New breakthroughs have provided critical insights into...

The discovery of a true Earth twin exoplanet (an Earth-mass planet orbiting a Sun-like star within the habitable zone) has been a long-standing goal in the field, and advances in observational technology over the past decades have been moving us...

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

Perhaps the most stunning surprise revealed by JWST yet is a class of compact, red, high-redshift sources (z~2-9) found in virtually every image the telescope takes. The sheer numbers of these ``Little Red Dots" demand that any satisfying theory of...
