The Wouthuysen-Field effect in a clumpy intergalactic medium
Jonathan Higgins, Avery Meiksin
We show that, due to the high optical depth of the intergalactic medium to Lyman-alpha photons before the Epoch of Reionization, the Lyman-alpha scattering rate responsible for the…
A High Yield of New Sightlines for the Study of Intergalactic Helium: Far-UV-Bright Quasars from SDSS, GALEX, and HST
David Syphers, Scott F. Anderson, Wei Zheng +6
Investigations of He II Ly-alpha (304 A rest) absorption toward a half-dozen quasars at z~3-4 have demonstrated the great potential of helium studies of the IGM, but the current cr…
Luminosity Function Constraints on the Evolution of Massive Red Galaxies Since z~0.9
Richard J. Cool, Daniel J. Eisenstein, Xiaohui Fan +6
We measure the evolution of the luminous red galaxy (LRG) luminosity function in the redshift range 0.1<z<0.9 using samples of galaxies from the Sloan Digital Sky Survey as well as…
Average Properties of a Large Sample of z_abs ~ z_em associated Mg II Absorption Line Systems
D. Vanden Berk, P. Khare, D. G. York +16
We have studied a sample of 415 associated (z_ab z_em; relative velocity with respect to QSO <3000km/s) Mg II absorption systems with 1.0<=z_ab<=1.86, in the spectra of SDSS DR3 QS…
