NICER observation list: Target ID 459501

Abstract

eROSITA, successfully launched in mid-2019, performs multiple all-sky X-ray surveys. By monitoring roughly half a million AGN/quasars, eROSITA identifies rare, accretion ignition/depletion events as they occur. We request 10 ToOs each with 20 ks to explore how the X-ray coronae in AGN respond to a sudden, major change in accretion rate. The NICER data will deliver the first medium signal-to-noise benchmark spectrum that later spectra can be compared to and to reveal the evolution of the photon index, possible intrinsic absorption, and flux. This will give valuable insights into the physics of AGN ignition/depletion and trigger several multi-wavelength campaigns.
