LATEST COSMOLOGICAL CONSTRAINTS FROM THE LYMAN-ALPHA FOREST
Lam Hui
Fermilab/University of Chicago

I will describe cosmological constraints obtained from analyses of the Lyman-alpha forest from the Sloan Digital Sky Survey (SDSS), as well as from other datasets. This will have bearing on the primordial power spectrum and the cosmological constant. I will also discuss our current understanding of the physics of the intergalactic medium, particularly the role of feedback and its impact on the above constraints. Finally I will discuss what WMAP and temperature measurements from the forest tell us about reionization history of the universe.
