NICER observation list: Target ID 558701

Abstract

X-ray observations of extreme accretion episodes provide a unique probe of the physics feedback from supermassive black holes. Whether due to some unknown disc instability, a stellar tidal disruption event or an encounter with an orbiting low mass compact object, such events change the accretion flow over timescales of weeks to months. X-rays are an essential part in understanding these extreme accretion episodes since they probe the regions closest to the black hole. NICER, in particular, is ideally suited for X-ray follow-up because it has flexible scheduling, a large effective area, good spectral resolution and lack of pile-up. We request to follow-up one bright extreme nuclear transient event for 150~days every 3~days for 1.5~ks (for a total of 75ks).
