Lyman-alpha Emitters During the Early Stages of Reionization
Andrei Mesinger, Steven Furlanetto
We investigate the potential of exploiting Lya Emitters (LAEs) to constrain the volume-weighted mean neutral hydrogen fraction of the IGM, x_H, at high redshifts (specifically z~9)…
Carbon-Enhanced Metal-Poor Stars, the Cosmic Microwave Background, and the Stellar IMF in the Early Universe
Jason Tumlinson
The characteristic mass of stars at early times may have been higher than today owing to the cosmic microwave background (CMB). This study proposes that (1) the testable prediction…
Ly-alpha Emission-Line Galaxies at z = 3.1 in the Extended Chandra Deep Field South
C. Gronwall, R. Ciardullo, T. Hickey +13
We describe the results of an extremely deep, 0.28 deg^2 survey for z = 3.1 Ly-alpha emission-line galaxies in the Extended Chandra Deep Field South. By using a narrow-band 5000 An…
Spin Exchange Rates in Proton-Hydrogen Collisions
Steven Furlanetto, Michael Furlanetto
The spin temperature of neutral hydrogen, which determines the optical depth and brightness of the 21 cm line, is determined by the competition between radiative and collisional pr…
