HI in the protocluster environment at z > 2: absorbing haloes and the Lyα forest.
WILMAN R.J., JARVIS M.J., ROETTGERING H.J.A. and BINETTE L.
Abstract (from CDS):
The strong absorbers may be a byproduct of massive galaxy formation or could instead represent material cooling behind the expanding bow shock of the radio jet, as simulated by Krause. New observations are required to discriminate between these possibilities. We argue that the weaker absorbers with NHi≃ 1013-1015/cm2 are part of the Lyα forest, as their rate of incidence is within a factor of 2-4 of that in the intergalactic medium at large. Such column densities are consistent with models of a multiphase proto-intracluster medium at z > 2.
