Long XMM observation of the Narrow-Line Seyfert 1 galaxy IRAS13224-3809: rapid variability, high spin and a soft lag
A. C. Fabian, E. Kara, D. J. Walton +21
Results are presented from a 500ks long XMM-Newton observation of the Narrow-Line Seyfert 1 galaxy IRAS13224-3809. The source is rapidly variable on timescales down to a few 100s.…

On the determination of the spin of the black hole in Cyg X-1 from X-ray reflection spectra
A. C. Fabian, D. R. Wilkins, J. M. Miller +9
The spin of Cygnus X-1 is measured by fitting reflection models to Suzaku data covering the energy band 0.9-400 keV. The inner radius of the accretion disc is found to lie within 2…
