Dr. Alireza Hojjati (Institute for the Early Universe, Ewha W. U.)

Lyman-alpha forest as a cosmological probe

Absorption of the ultra violet light (the Lyman-alpha lines) offers a unique probe of the neutral Hydrogen along the line of sight of quasars, which in turn is a way to trace dark matter distribution at high redshifts. After an introduction to the basics, I discuss some of the theoretical assumptions and approximations applied in describing the phenomena and how they can impact the estimation of cosmological parameters.
