Title : Intergalactic medium probed by Lyman-alpha forest: Clutering and its evolution
Authors : Raghunathan Srianand
Abstract Type: Invited
Abstract Category : Extragalactic Astronomy
Abstract : Lyman alpha absorption seen in the spectra of distant quasars allow us to probe the evolution of physical conditions in the universe and cosmological parameters. In this presentation we will review the recent advances in the measurements of (i) the UV background, (ii) temperature and effective equation of state and (iii) redshift-space clustering. A discussion on what is required in the hydro-dynamical simulations to reproduce the above mentioned observational results will be presented.
