Zooming in on the central regions of a radio-loud AGN -- 3C120
Abstract
3C120 is a bright radio-loud AGN (RLAGN) in which a clear disk-jet connection has been established. We will present the best snapshot to date of the central engine structure in any RLAGN, taken with Suzaku in Febuary 2012. To place this deep Suzaku stare into the context of the disk-disruption/jet-ejection cycles displayed by this object, we also have a monitoring of the source in the UV/X-ray (Swift) and radio bands (UMRAO, VLBA) for half-year around the deep stare. The Swift monitoring provides important information on disk activity in both corona (XRT) and thermal disk emission (UVOT) during the Suzaku and radio campaigns. This places the Suzaku observation in context with the disk and jet (radio) cycles of activity and therefore provide us with the detailed knowledge of the continuum shape and variability. Utilizing this unprecedented knowledge of the continuum, we constrain the accretion disk parameters in this radio-loud AGN from the broad iron line and search for ultra-fast outflows in the iron K band. Taken as a whole, this campaign will give a detailed view of the physics of a RLAGN.
