Fe-K Accretion Disk Diagnostics From Suzaku Observations Of The LINER NGC 1052: A Tool To Probe Disk-jet Coupling
Abstract
Relativistically broad iron lines in active galactic nuclei (AGN) provide a powerful diagnostic probe of the inner accretion flow onto supermassive black holes. It is thought that the formation of relativistic jets is closely related to black hole/accretion disk dynamics; observations in support of this hypothesis have been lacking, however. The LINER NGC 1052 represents the rare case of a radio-loud AGN with a prominent compact jet structure and a broad Fe-K line indicative of an origin in the inner disk. As part of a multi-mission monitoring program begun in 2005, including VLBI radio observations and several pointings with different X-ray missions, an 83-ks Suzaku spectrum has yielded the highest signal-to-noise X-ray spectrum of NGC 1052 to date. We present the results from this observation as well as a comparison of the state of the disk during different epochs based on past data from BeppoSAX, Chandra, and XMM-Newton. The X-ray data allow us to differentiate between competing continuum models and to trace changes in the morphology and strength of the iron line and surrounding continuum with changes in the jet structure.
