Assessing black hole spin in deep Suzaku observations of Seyfert 1 AGN.

Abstract (from CDS):
Fitting relativistic line emission models appears to rule out the presence of maximally spinning black holes in all objects at the 90 per cent confidence level, in particular MCG-6-30-15 at >99.5 per cent confidence. Relativistic Fe K line emission is only marginally required in NGC 3516 and not required in NGC 4051, over the full energy bandpass. None the less, statistically significant broadened 6.4 keV Fe Kα emission is detected in Fairall 9, MCG-6-30-15 and NGC 3783 yielding black hole spin estimates of a= 0.67+0.10_- 0.11_, a= 0.49+0.20_- 0.12_and a < -0.04, respectively, when fitted with disc emission models.
