NICER observation list: Target ID 657401

Abstract

Large-scale time-domain surveys have lead to the identification of new types of extreme variability in active galaxies, called 'changing look' active galactic nuclei (CL-AGN). The drastic changes seen in CL-AGNs in such short timescales (a few months to years) involves large fluctuations (and even complete disappearance) of the coronal X-ray emission and then its revival/re-heating. The CL-AGN are therefore ideal test beds to understand the properties of the AGN central engine and the coronal X-ray emission, in particular. This observational program aims to capture 2ks snapshots of the $0.3-10\kev$ X-ray spectra of a CL-AGN, bi-weekly for 6 months (total 96ks), to understand how the spectral and physical properties of AGN corona, and soft X-rays evolve during these violent phases.
