Galaxies and Dark Matter Halos
(Prof. Andreas Berlind)
We will study the properties of galaxies and galaxy groups/clusters in the Sloan Digital Sky
and connect them to the properties of dark matter halos. The goal is to constrain galaxy
as well as cosmological parameters. Projects available for REU students will include analyzing
to measure galaxy clustering, as well as data from large cosmological N-body simulations to
Computational Simulations of Black Hole Formation
(Prof. Kelly Holley-Bockelmann)
We will use high resolution N-body simulations and numerical models
to understand how black holes grow within galaxies. Projects for
REU students will include calculating the gravitational wave signal
from merging supermassive black holes, modeling black holes
in triaxial galaxies, and studying the effect of isolation on
black hole growth.
Star Formation and Extrasolar Planets
The Stassun group is conducting observational studies to understand the birth of stars and to search for planets around other stars.
The star formation research includes time-series photometric studies of young stars in a variety of star-forming regions in order to characterize the evolution of the stars' angular momenta and also to search for eclipsing binary stars with which to measure the fundamental properties of newly formed stars. The exoplanets research includes searches for signals of "transiting" planets through the examination of data streaming from Vanderbilt's Kilodegree Extremely Little Telescope (KELT) in South Africa as well as radial-velocity data from the Sloan Digital Sky Survey's MARVELS project. An observing run in Chile is possible. A related set of projects involves SLoWPoKeS for discovery and analysis of extremely wide binary star systems both as sites of possible exoplanet formation and also as probes of stellar evolution and galactic structure.
