NICER observation list: Target ID 553502

We propose high-cadence NICER observations of two tidal disruption events (TDEs). First, we will test if features observed in stellar mass black holes (BHs) exist in massive BHs, such as the rapid evolution of disk temperature and power-law slope, quasi-periodic oscillations, and reverberation lags. For non-jetted TDEs, this program will confirm the scale (in)variance nature of the underlying physics governing the accretion onto stellar mass BHs and massive BHs. For relativistic TDEs, the observations will shed light on the power mechanism of TDE jets. Second, by combining NICER with contemporaneous UV/optical observations, we will study the interplay between the X-ray emitting disk and the reprocessed emission in the optical, and constrain the origin of the reprocessing layer.
