This is a talk held during the regular colloquium series (usually Tuesdays at 4pm).
On August 31, 2017, a total solar eclipse's band of totality swept across the Continental United States from coast to coast for the first time in 99 years.
Supernovae (SNe) and Long-duration Gamma-ray Bursts (GRBs) are exploding stars and constitute the most powerful explosions in the universe.
The plurality of galaxies in today’s Universe and their structure can give insight on their formation and evolution as well as on physical processes at play.
A prime objective of observational astrophysics is to characterize the earliest sources in the first Gyr of the universe, by directly observing the cosmic times when the first stars, black holes, and galaxies formed.
The lowest-mass stellar systems offer a unique and powerful path for examining fundamental questions in galaxy formation and dark matter physics. I will discuss how globular clusters and dwarf galaxies are providing tests of the LCDM model in the local Universe and at high redshifts.
The success of ground-based transit and RV surveys, and the Kepler/K2 mission, has shifted the exoplanet field from pure discovery to a combination of discovery, demographic analysis, and detailed characterization, especially for exoplanet atmospheres.
