Astronomy Colloquium
New Views of Black Hole Disk Winds
Date: Thursday, September 24th
Time: 3:45 pm
Place: 4421 Sterling Hall
Speaker: Jon Miller, University of MI
Abstract: High-resolution X-ray spectroscopy has been central to revealing the nature of X-ray winds from accreting massive black holes. These winds may ultimately have important effects on the evolution of host galaxies. However, early studies with Chandra may have given a partially skewed view of the radii at which such winds originate, and the mechanisms by which they are driven. With an eye toward the coming Astro-H era, I will briefly review past results, and then highlight some new and emerging views of black hole disk winds. Where possible, I will draw analogies between parallel investigations in accreting stellar-mass black holes. Overall, new results suggest that disk winds may originate closer to the black hole, and carry much more
mass and power than previously appreciated.
