NICER observation list: Target ID 364201

Abstract

Black Hole X-ray binaries regularly show transitions from a power law dominated hard state to a blackbody dominated soft state, and back again. However, these transition do not occur at the same luminosity, with the hard to soft transition occurring at luminosities that are a factor of few higher than the soft to hard state transition. Recent higher order analysis of black hole X-ray binaries over the course of outbursts have shown some evidence that the non-linear properties during these two phases of the outburst are different. We propose ToO observations consisting of 10 NICER observations of 2.5ks each, covering two different stages of the outburst, which will provide valuable insight into the origin of this hysteresis.
