Peter Creasey

with Prof. Laura Sales

Office: Pierce Hall 2209

Research Interests: my primary interest is in numerical simulations of galaxy formation and the role of stellar feedback. In a lambda cold dark-matter cosmology the process of galaxy formation is that of gravitational collapse of primordial density perturbations, enhanced for the baryonic component by the loss of pressure support due to gas cooling. Nevertheless, galaxies like our own Milky Way are believed to have ejected a significant fraction of their baryons, most likely due to the energy released when massive stars expire as supernovae. My research centres around the challenging numerical simulation of such processes, which involve a large dynamic range of scales to combine the mega-parsec scales of galaxy formation to the parsec scales of supernova remnants.

Ryan Mallery

with Prof. Bahram Mobasher

Research interests: I am interested in Lyman-alpha emitters at both low and high redshifts, and understanding the different feedback processes that give allow for Lyman-alpha photons to escape from galaxies. At low redshifts (z~0.2) I probe the morphology and Balmer extinction of Lyman-alpha emitters detected by GALEX. At high redshift I am studying the evolution and interrelatedness of EWs, SFRs, M*, and outflow velocities in Lyman-alpha emitters. I am also interested in metallicity evolution of galaxies, especially in the variation of nitrogen and oxygen as a function of specific star formation rate.
