The escape of ionizing photons from supernova-dominated primordial galaxies

Understand

In order to assess the contribution of Lyman break galaxies (LBGs) and Lyman alpha emitters (LAEs) at redshifts 3<z<7 to the ionization of intergalactic medium (IGM), we investigate the escape fractions of ionizing photons from supernova-dominated primordial galaxies by solving the three-dimensional radiative transfer.

• The model galaxy is employed from an ultra-high-resolution chemodynamic simulation of a primordial galaxy by Mori & Umemura (2006),which well reproduces the observed properties of LAEs and LBGs.
• The total mass of model galaxy is 10^{11}M_sun.
• We solve not only photo-ionization but also collisional ionization by shocks.
