SUMMARY:Measuring Black Hole Spin - Ramesh Narayan\, Harvard

DESCRIPTION:An astrophysical black hole is completely described with\njust
  two parameters: its mass and its dimensionless spin.  A few\ndozen black 
 holes have mass estimates\, but until recently none had a\nreliable spin e
 stimate. In the last few years\, our group has measured\nspin parameters f
 or a small number of black holes in X-ray binaries.\nThe talk will describ
 e the method we use to make these measurements\nand will discuss implicati
 ons of the results obtained so far.\n
