NICER observation list: Target ID 260201

Abstract

X-ray/UV/optical AGN monitoring shows consistent behavior within the UV/optical but a disconnect between X-ray and UV/optical broadband flux variations that challenges the standard reprocessing model. Mrk 876 lies in the TESS continuous viewng zone providing a high S/N light curve sampled every 30 minutes for ~1 year. During this period we will obtain simultaneous monitoring from the ground (approved) and Swift (pending), but Swift only provides a low S/N X-ray light curve. As NICER is a factor of ~20 more sensitive, it allows monitoring of individual components in the complex X-ray spectrum. By correlating these components (instead of broadband X-ray fluxes) with the UV/optical, NICER can break this degeneracy and allow us to determine which X-ray component drives the disk variability.
