| Research Abstract |
Quasars, active galactic nuclei at distant universe, have quite important consequences to interstellar and intergalactic media through their outflowing winds with enormous energy. The winds are detected as absorption profiles on the spectra of quasars. Based on monitoring observations over ~10 years, photoionization modeling, and new acquisition of a polarization spectrum, we discovered interesting properties of the winds such as (a) variability of absorption profile depends on their line widths and (b) the winds have experienced an intense star forming activity in the past, and expanded the knowledge of their geometrical structures.
