Spectra from Forming Region of the First Galaxies : The Effect of Aspherical Deceleration
Masakazu AR. Kobayashi, Hideyuki Kamaya
Ly line emission from the Loeb-Rybicki (LR) halo, which is the expanding HI IGM (intergalactic medium) around the first star clusters and the ionized interstellar medium, is inv…
