SUMMARY:Probing the Gas Around Galaxies and Black Holes\, Astronomy Co
 lloquium\, Aleks Diamond-Stanic\, UC San Diego
DESCRIPTION:Our understanding of galaxy evolution centers around quest
 ions of how gas gets into galaxies\, how it participates in star forma
 tion and black hole growth\, and how it is returned to its galactic <b
 r>
\nsurroundings via feedback.  I will present results on the relatio
 nship between gas that forms stars and gas that accretes onto supermas
 sive black holes\, and the nature of feedback that is capable of remov
 ing gas from galaxies.  These results have important implications for 
 how radiation\, momentum\, and kinetic energy from stars and black hol
 es regulate the cold gas supply in <br>
\ngalaxies.  I will also discu
 ss prospects for characterizing the physical properties of gaseous out
 flows and inflows using existing and future facilities.
