Abstract

We present results from a 150 ksec Suzaku long-look of the Seyfert 1 galaxy NGC 3516 in October 2005. The wide bandpass obtained from combining Suzaku's X-ray Imaging Spectrometer (XIS) and Hard X-ray Detector (HXD) enables us to deconvolve broadband emitting and absorbing components in this object, namely the underlying continuum, the ionized absorber, the partial-covering absorber, the broad Fe K line and the Compton reflection hump, as well as a soft power law component which may be scattered emission. We find that the column density of the ionized absorber has increased by a factor of about three since XMM observations in 2001. We confirm the presence of the broad Fe line, finding a 190 eV equivalent width line that indicates emission extending down to a few Schwarzschild radii and suggests a rotating black hole. The XIS's high effective area and low background near 6 keV also allows us to resolve the narrow Fe K core. We find a FWHM velocity width near 4000 km/sec, commensurate with the Broad Line Region. We also significantly detect the core's Compton shoulder and the Fe K beta line. An edge at 7.3 keV is likely associated with ionized reflection....
