" On the connection between the IGM and galaxies at z<1 "

Nicolas Tejos

(UC Santa Cruz)

I will present observational results on the large-scale connection between the intergalactic medium (IGM) and galaxies at z<1. I will focus on a statistical approach to this problem by measuring the gas-galaxy 2-point cross-correlation, and comparing it with both the galaxy-galaxy and the gas-gas auto-correlations, as a function of different absorber/galaxy properties. These results come from one of the largest samples of HI absorption lines and galaxies in the same volume obtained from deep spectroscopic galaxy surveys (VLT/VIMOS, Gemini/GMOS, Keck/DEIMOS) around QSOs having high resolution UV spectroscopy (HST/COS, HST/FOS). I will also present results from a complementary study on HI absorption systems found within and around galaxy voids at z<0.1.

Seminars are also held at JAC, CFHT, and IfA.
