NICER observation list: Target ID 857201

3C120 is a unique broad-line radio galaxy. Alongside the vast jets launched by the supermassive black hole in its nucleus, 3C120 possesses a compact X-ray emitting corona that irradiates the inner disk. This provides a unique view of the inner regions around the black hole in which the jet is launched and the corona is formed. We propose weekly X-ray spectral monitoring of 3C120 over the course of a year using NICER to accompany an ongoing VLBI monitoring campaign. Long-timescale X-ray spectral monitoring of 3C120 will add to a legacy dataset that will allow variations in the jet (traced by radio emission) to be correlated with variations in the inner disk and corona (traced by the X-rays), providing important new insight into the mechanism by which jets are launched by black holes.
