NICER observation list: Target ID 659301

Abstract

We propose NICER monitoring observations of the nucleus of the spiral galaxy NGC 4845, IGR J12580+0134, the nearest tidal disruption event (TDE) candidate with off-axis relativistic jets that occurred at the beginning of 2011 and in the middle of 2016. Our goal is to track the soft X-ray excess, which could soon have an X-ray or/and radio outburst based on the outburst cycle in 2011-2019 lightcurves. NICER is perfectly suitable for X-ray monitoring because of its large soft X-ray effective area without pile-up and superb time resolution. The NICER observations will allow us to trace the origin of thermal emission in the soft excess, and detect a future TDE for the hardness timing analysis at different epochs and follow-up radio observations of a relativistic jet.
