A Concordance Model of the Lyman-alpha Forest at z = 1.95
T. Jena, M. L. Norman, D. Tytler +12
We present 40 fully hydrodynamical numerical simulations of the intergalactic gas that gives rise to the Ly-alpha forest. We make artificial spectra from each and measure three out…

Cosmological parameters sigma_8, the baryon density, and the UV background intensity from a calibrated measurement of H I Lyman-alpha absorption at z = 1.9
David Tytler, David Kirkman, John M. O'Meara +7
We identify a concordant model for the intergalactic medium (IGM) at redshift z=1.9 that uses popular values for cosmological and astrophysical parameters and accounts for all bary…
