NICER observation list: Target ID 753701

Abstract

SDSS-V, now in its full operation, will obtain repeated optical spectroscopy for thousands of AGN. This will allow for the optical identification of currently transiting changing-look AGN. We request 5 ToOs each totaling 60 ks (2 ks roughly every 4 days for 120 days) to explore how the X-ray corona, optical accretion disc, and broad-emission line region interact with each other. The NICER data will also deliver several spectra over the proposed 120 day period, which will be used to constrain the evolution of the photon index. This data set, combined with guaranteed high-cadence optical monitoring & spectroscopy, will give valuable insights into how accretion flows evolve during AGN ignitions and depletions.
