H. S. Murdoch, R. W. Hunstead, Max Pettini, J. C. Blades

Open full text 1 citations

Abstract

It is now widely accepted that a population of intergalactic hydrogen clouds is responsible for the plethora of absorption lines seen at wavelengths shorter than Ly α emission in all high-z QSOs. The question of whether the comoving number density of such clouds evolves with redshift has been somewhat controversial. It is usually assumed that
