I will discuss how black holes can become nature's laboratories for ultralight axions. When a boson's Compton wavelength is comparable to the horizon size of a black hole, energy and angular momentum from the black hole are converted into...

As fusion enters a phase aiming at harnessing fusion energy, new plasma facing materials (PFMs) and components that are able to withstand the harsh conditions of fusion reactors need to be developed. Solution are needed for PFMs to be irradiation...

Central massive black holes will reveal themselves in a galaxy when they flicker and flare as they feed on gas and stars. We are conducting a systematic study of nuclear transients in the Zwicky Transient Facility alert stream, and have assembled...

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...

Most globular clusters (GCs) show evidence for multiple stellar populations, suggesting the occurrence of two or more distinct star-formation episodes. The large fraction of second population (2P) stars observed, require a very large 2P gaseous mass...
