The study of the many processes that take place within astrophysical systems e.g., magnetic reconnection, shocks, and turbulence is made very challenging by the large separation distances between us and these systems. This is especially true for...

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...

Pulsars are rapidly rotating neutron stars immersed in strong electromagnetic fields that emit twin beams of electromagnetic radiation. However, the plasma composition and structure in the region surrounding pulsars, called magnetospheres, and the...

The VLA Sky Survey (VLASS) has delivered the first deep, unbiased view of the northern radio sky, offering an unprecedented opportunity to perform a systematic and unbiased survey of the late-time radio emission from the tens of thousands of...

Abstract: In this talk I will focus on light dark matter particles, with a mass between 1 MeV and a few GeV. These particles can annihilate or decay into electron-positron pairs which can upscatter the low-energy fields in our Galaxy and produce X...

Fast and Blue Optical Transients (FBOTs) emerged in the past decade as a new class of astronomical transients. With extremely rapid time scales of evolution and luminous emission, FBOTs likely probe the extremes of the explosion parameters and/or...

After the landmark neutron-star merger event GW170817, the frontier is now to map the properties of a population of neutron star mergers, find electromagnetic counterparts of NS-BH mergers, and connect the pre-merger to the post-merger properties of...
