Hot gas plays a vital role in shaping galaxy formation and evolution. ?However, even though we live in a disk galaxy, we know very little ?about the distribution of the hot gas, and how it impacts disk galaxy ?evolution via the so-called “circumgalactic medium”. In this talk, I ?will discuss several outstanding questions in this field, including ?problems such as the “missing galactic baryons” and “missing stellar ?feedback”. I will also discuss in general how addressing these ?questions can help understand the baryonic matter distribution in the universe.

Taotao Fang is a professor at Xiamen University. He did his ?Ph.D at the Massachusetts Institute of Technology. He was a postdoc at ?Carnegie Mellon University and also at the University of California at ?Berkeley as a Chandra Fellow. He then went to the University of ?California at Irvine as a research scientist before he joined Xiamen ?University. His research interest lies primarily in exploiting ?cosmological simulations and multi-wavelength observations of the ?intergalactic medium (IGM), the main repository of baryons in the ?universe, and its interaction with galaxies.
