Understanding the nature of dark matter is one of the major goals of modern physics.   The abundance and density profiles of dark matter halos depend directly on dark matter particle physics. Strong gravitational lensing enables a direct measurement...

Collisionless shocks are ubiquitous in space and astrophysical plasmas, where they often mediate conversion of flow energy into particle acceleration and heating. In hot and rarified (weakly collisional) plasmas, the energy dissipation must be...

Gas-rich environments are ubiquitous in various scales, from protoplanetary disks to star clusters and galaxies. Dynamics in gas-rich environments are substantially different and give rise to unique astrophysical phenomena, along with enhancing the...

Fast radio bursts (FRBs) are a recently discovered, poorly understood class of transient event, and understanding their origin has become a central problem in astrophysics. I will present FRB science results from CHIME, a new interferometric...
