Abstract:  Self-interacting dark matter (SIDM) offers the potential to mitigate some of the discrepancies between simulated cold dark matter (CDM) and observed galactic properties.  In various SIDM models, dark matter particles can scatter with each...

The Bahcall Lunch follow the astrophysics colloquium lecture. Registration is required by 3pm the previous Friday so a meal can be provided. Please contact Amanda Cenker with questions.

For the first time, the entire visible sky is being surveyed for the violent, variable, and transient events that shape our universe by the All-Sky Automated Survey for Supernovae (ASAS-SN). Combined, ASAS-SN, Asteroid Terrestrial-impact Last Alert...

Abstract: Gravitational waves provide a unique observational handle on the properties of strong, dynamical gravity. Black hole ringdowns, in particular, cleanly encode information about the structure of black holes, allowing us to test fundamental...

With dedicated exoplanet surveys underway for multiple extreme precision radial velocity (EPRV) instruments, such as the Terra Hunting Experiment on HARPS-3, the near-future prospects of RV exoplanet science are promising. These surveys' generous...

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 standard magnetorotational instability (SMRI) has been regarded as the most promising instability responsible for the turbulence required to explain the fast accretion observed across the Universe. However, unlike other fundamental plasma...
