NICER observation list: Target ID 662403

Abstract

Tidal disruption events (TDEs) provide a dynamic view of supermassive black hole (SMBH) accretion. We propose a 3-epoch, 144 kilosecond snapshot survey of all newly discovered X-ray bright TDEs with NICER, in order to i) provide the first quantitative constraints on the ubiquity of ultra-fast outflows (UFOs), associated to near or super-Eddington accretion, and ii) study in detail the evolution of the accretion disk, enabled by state of the art relativistic thin accretion disk modeling. The proposed observations will constrain the temperatures and radii, as well as Eddington ratios and bolometric corrections of newly formed TDE disks. Combined with constraints on the presence of UFOs, this will help to elucidate the hotly contested nature of the poorly understood UV/optical emission.
