A TWO WEEK ASCA OBSERVATION OF MCG-6-30-15
ABSTRACT
ASCA has made an important contribution to physics and astronomy with the discovery of the broad, redshifted, profile of the iron line in Seyfert 1 galaxies, indicative of emission from matter within a few Schwarzschild radii of a black hole (see Tanaka et al 1995). During the previous 4.5 day observation the line was briefly seen to show a greater redshift, suggesting that the accretion disk extends close enough to the event horizon that a Kerr metric is needed. This means that the black hole is probably spinning. No other observations are able to penetrate this close to a black hole; ASCA has opened up black hole physics to observational study. We propose here to re-observe MCG-6-30-15 for a full two weeks with ASCA to confirm and extend the evidence that the black hole is spinning.
