Rupert Croft’s main research interests are in computational cosmology, involving both simulations and the analysis of data from large surveys. This includes the physics of the intergalactic medium and its use as a probe of cosmology and of galaxy and quasar formation. He is participating in the SDSS surveys of galaxies and quasar absorption lines which are constraining dark energy, and is making the first “intensity mapping” measurements of structure using optical emission lines.  Croft also works on the re-ionization of the Universe, and high redshift galaxies, as well as new cosmological probes of modified gravity, such as gravitational redshifts and other relativistic effects which are just starting to be measured from galaxies and large-scale structure. He makes use of the McWilliams Center’s high performance computing facilities, including the Warp and Coma clusters to analyze SDSS data and perform cosmological hydrodynamic and radiative transfer simulations.
