NICER observation list: Target ID 356601

Abstract

The origin, structure and dynamics of the nuclear obscurer of Active Galactic Nuclei, the 'torus', is still poorly understood. Drastic column densities variations are signatures of torus clumps transiting the line-of-sight, and give insight into the obscurer granularity. eROSITA's spectral monitoring of bright AGN on the entire sky enables a systematic search for such occultations on novel time-scales. NICER observations are needed to constrain crucial physical parameters, such as the column density and intrinsic luminosity. We propose to monitor the column density in depth with a systematic cadence to understand the substructure of individual torus clumps in two new occultations.
