Minihalo model for the low-redshift Lyα absorbers revisited

Minihalo model for the low-redshift Lyα absorbers revisited

We reconsider the basic properties of the classical minihalo model of Rees and Milgrom in light of the new work, both observational (on 'dark galaxies' and masses of baryonic haloes) and theoretical (on the cosmological mass function and the history of star formation). In particular, we sh...
