Astrophysics Calendar

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...

Dynamical tracers of planets, such as their eccentricity, inclination, orbital obliquity, and spin rate, can be used to constrain and refine planet formation and evolution processes. I will begin the talk with mature planetary systems and show how...

The prospect of an ultra-light dark matter particle (also known as Fuzzy Dark Matter, or FDM) has recently drawn attention as a promising alternative to standard Cold Dark Matter (CDM). When the mass of the particle reaches below 10^-21 eV, quantum...

Cosmic rays, the relativistic component of diffuse astrophysical plasma, exchange energy and momentum with the thermal gas collisionlessly, mediated by the ambient magnetic field. Some but not all models of this interaction show that cosmic rays can...

The giant impact theory for the formation of the Moon suggests that a planetary impactor struck the proto-Earth in an oblique collision shortly after the formation of the solar system. This collision produces liquid and vapor debris, drawn from the...
