Abstract: The large-scale structure of our Universe is well described by a model in which matter is predominantly Cold Dark Matter (CDM). While CDM was initially thought to have trouble reproducing the small scales of our Universe (dwarf galaxies...

The Bahcall Lunch follows the astrophysics colloquium lecture. Registration is required by 4pm the previous Thursday so a meal can be provided. Email Amanda at cenker@ias.edu with questions.

There is a revolution afoot in our understanding of supermassive black holes (SMBHs), that is reshaping our view of their formation, growth and influence on cosmic architecture. This talk will spotlight three recent breakthroughs that have enriched...

Primordial magnetic fields (PMFs) offer a simple explanation for the origin of galactic magnetic fields as well as of the purportedly detected magnetic fields in cosmic voids. In the talk, I discuss how PMFs' influence on structure formation can...

Abstract: The existence of multi black hole solutions in asymptotically flat spacetimes is one of the expectation from the final state conjecture. In this talk, I will present preliminary works in this direction via a semilinear toy model in...

With the advent of JWST, the need for detailed chemical and photochemical models of exoplanet atmospheres has increased. Traditionally, building reaction networks required manually tracking species and reactions, a process that is both time...

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...

More than a century ago, Albert Einstein presented his general theory of gravitation. One of the predictions of this theory is that not only particles and objects with mass, but also the quanta of light, photons, are tied to the curvature of space...

Observations of the large-angular-scale autocorrelation function and power spectrum of the cosmic microwave background (CMB) over the last 30 years have consistently provided hints that our standard LCDM cosmological model may be inaccurate. One...
