Galaxy Collisions at High Redshift
We will identify and measure the signature of recent galaxy mergers at high redshift by quantifying tidal features (the stellar mess that mergers leave behind). We will do so using images from the Hubble space telescope. Such an analysis has not yet been done for galaxies at high redshift and it would provide an important…Continue Reading Galaxy Collisions at High Redshift

Dwarf Galaxies in a Dense Environment
Dwarf galaxies are the most common galaxy type in the Universe. They come in a few different flavors. The ones in the dense Coma cluster of galaxies are inert (i.e., non-star-forming) and belong to a class of galaxies known as “dwarf ellipticals” (dEs). The physical origin of this class of galaxies remains poorly understood. The…Continue Reading Dwarf Galaxies in a Dense Environment

Scattered Light from Quasars: Connecting Deep Observations with State-of-the-Art Computer Simulations
Quasars are the most luminous persistent sources in the sky, powered by rapid accretion onto a supermassive black hole in the center of a galaxy. The extreme energy output of a quasar is theorized to cause dramatic impacts on their host galaxies, like rapidly quenching star formation and launching enormous jets. But measuring the properties…Continue Reading Scattered Light from Quasars: Connecting Deep Observations with State-of-the-Art Computer Simulations
The Role of Supermassive Black Holes in Quenching and Triggering Star Formation
Every galaxy hosts a supermassive black hole in its center, and the masses of each are correlated over several orders of magnitude. This suggests that the mass growth of a galaxy (through star formation) is tightly coupled to the mass growth of its black hole (through accretion of gas and stars). But the physics behind…Continue Reading The Role of Supermassive Black Holes in Quenching and Triggering Star Formation
Modeling the Atmospheres of Exoplanets
We are now in the era where advanced telescopes can detect light emitted by warm planets. The temperature structure and spectra of these atmospheres depend on a number of factors: The amount of stellar light coming from the parent star, the amount of energy coming from the planet’s interior, the abundances of molecules in the…Continue Reading Modeling the Atmospheres of Exoplanets
Measuring Barium Isotopes in Stars
The elements of the periodic table come in different forms called isotopes. Different isotopes of the same element have the same number of protons but different numbers of neutrons. The distribution of isotopes of a single element can be measured in stars using high-precision spectroscopy. This project involves measuring the amounts of different barium (element…Continue Reading Measuring Barium Isotopes in Stars
The Colors of the Most Massive Galaxies in the Universe
A study of the most massive galaxies in the nearby universe from looking at their optical colors. This project will utilize images from the Sloan Digital Sky Survey, the world’s most extensive data set of galaxies at low redshift, to trace the color profiles of nearby elliptical galaxies out to an unprecedented radius. A possible…Continue Reading The Colors of the Most Massive Galaxies in the Universe
