Webcross-section to produce a DLA increases with the halo mass M h at least as steeply as DLA ∝ M h. The results also show there is no dependence of the DLA bias on hydrogen column density, and no evolution with redshift to within measurement errors. There are other observable properties of DLAs, however, that we expect the bias factor to depend on. Webtransition in hydrogen assuming you have a gas cell of hydrogen atoms at room temperature.
