摘要：
Systems producing absorption in the spectra of distant quasars offer an excellent probe of the early Universe. At high redshifts, they easily outnumber other observed tracers of cosmic structure, including both normal and active galaxies. We summarize the results of a method whereby we employ particle simulation techniques to calculate the number of damped Lyman-alpha absorbers in various popular cosmological models.
