An X-Ray View of the Jet-Cycle in the Radio Loud AGN 3C120

Understand

We present a study of the central engine in the broad-line radio galaxy 3C120 using a multi-epoch analysis of a deep XMM-Newton observation and two deep Suzaku pointings (in 2012).

• In order to place our spectral data into the context of the disk-disruption/jet-ejection cycles displayed by this object, we monitor the source in the UV/X-ray bands, and in the radio band.
• We find three statistically acceptable spectral models, a disk-reflection model, a jet-model and a jet+disk model.
• Despite being good descriptions of the data, the disk-reflection model violates the radio constraints on the inclination, and the jet-model has a fine-tuning problem, requiring a jet contribution exceeding that expected.
