This year, NASA is beginning its search for a Probe-class ($1B) mission to fly in ~2032. This once-per-decade opportunity was endorsed by astro2020 as a way to achieve some of the science promised by the more complex and expensive far-infrared and X...

The COVID-19 pandemic has impacted the personal and professional lives
of people worldwide. In my talk, I am going to present results from a
recent study, in which my colleague Jia Liu and I have analyzed its
impact on the astronomy community using...

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...

Abstract: The study of hyperuniform states of matter is an emerging multidisciplinary field, influencing and linking developments across the physical sciences, mathematics and biology. The hyperuniformity concept generalizes the traditional notion...

Although hot Jupiters were the first exoplanets to be discovered, and hundreds are now known, the current sample is drawn mainly from a heterogeneous collection of ground-based transit surveys. Our simulations show that the distribution of hot...

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...
