Dependences of QSO Ly absorption line statistics on cosmological parameters
Dependences of QSO Ly absorption line statistics on cosmological parameters
We have performed high-resolution hydrodynamic simulations of the Ly α forest in a variety of popular cold dark matter dominated cosmologies, including a low density and a vacuum-dominated model. The fluctuation amplitude of these models is chosen to match the observed abundance of galaxy clusters at low redshift. We assume …
