A quasar is an extremely bright point source in the high-z uni-
verse, providing an unique technique to probe the medium along the line-of-sight. The emission of a quasar goes through a galaxy, the spectroscopic absorption lines gives us information about inter- stellar-medium (ISM) in the galaxy. Thus the absorption lines are widely used as a strong tool to study the physical conditions of the gas in the intervening systems. I will introduce how we select the sample, obtain the physical properties of the ISM from the quasar spectrum and how we connect the results to the star formation and galaxy evolution. |
