PPT-The Most Luminous Quasars

Amy Kimball NRAO Charlottesville NAASC Why is quasar feedback important for galaxy formation and what are the two feedback modes How to identify candidate most extreme feedback objects. The Xray absorbing gas is often called a warm absorber because UV observations show that it is accompanied by very weak or no signi64257cant absorption at the H I Lyman limit 912 A The gas must be substantially ionized much more H II than H I and he Vocabulary – Week 6 (VQ6).
