Distant Galaxies

Distant Galaxies

Our group is interested in how galaxies form and evolve into present day galaxies. Our research focuses on a range of galactic formation and evolution questions by using innovative observational techniques with a range of multi-wavelength ground-based and space-based telescopes. Our team has a particular focus on using high angular resolution observations that couples integral field spectrographs (IFS) and adaptive optics (AO) observations.

The advent of IFS and AO has been revolutionary for studying distant galaxies at high angular resolution observations on sub-kiloparsec (~2500 light years) scales. These studies have shown the nitty-gritty of distant galaxies’ star formation histories, metal content, their internal motions (or kinematics), and supermassive black hole activity. The IFS also allows us to study both resolved nebular line ratios and kinematics allows us to explore that star formation histories, as well as infall/outflow and the role and strength of feedback during this critical epoch of galaxy evolution.
