Quasar L-alpha absorbers - Are precise conclusions possible
Abstract
The conclusions of a massive study of QSO absorption lines (Sargent et al.) are critically examined. It is found that tight constraints may not be placed on the nature of pressure-confined clouds nor on the intergalactic medium presumably confining them. An alternative model, of gravitationally bound clouds, is found to be equally viable
