This is a talk held during the regular colloquium series (usually Tuesdays at 4pm).
In the second of four GMT talks this fall, we will focus on two related issues regarding the current effort in the GMT project: the scientific goals and in
It has now been 20 years since the discovery of 51 Peg b, the first planet around another Sun-like star. Since then, many discoveries have revolutionized our understanding of how planetary systems form and evolve. At the same time, we are still grappling with the problem posed by that first dis
For the first time, the entire visible sky is being surveyed for the violent, variable, and transient events that shape our universe. To accomplish this, my collaborators and I built the All-Sky Automated Survey for Supernovae (ASAS-SN), which is a long-term project to monitor the whole sky, at
NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, launched in June 2012 and became the first telescope in orbit to focus high energy X-ray light above 10 keV. This powerful X-ray emission provides a unique probe of the most energetic phenomena in the universe, from flares on the surface o
The Local Group is home to ~100 galaxies less massive than the Small Magellanic Cloud (10^8 Msun). Such low-mass galaxies have become increasingly relevant to a broad range of astrophysics from cosmic reionization to deciphering the nature of dark matter. Yet, they are simply too faint to be di
