NICER observation list: Target ID 255303

Abstract

The launching of jets from accreting systems is an established (albeit poorly understood) phenomenon. Whilst typically studied at sub-Eddington rates of accretion, jet ejections are known to occur in our Galactic super-critical source, SS433 and the ULX, Ho II X-1. We are proposing a series of NICER snaphots, coordinated with pre-approved observations using the JVLA and AMI radio telescopes to reveal how the properties of the accretion flow (i.e. the continuum X-ray emission and atomic features associated with a wind) change with respect to jet ejections. Based on recently discovered variability in the ejections from Ho II X-1, we are proposing an observing cadence of one every 1-2 months. NICER is crucial to our science goals as it combines high throughput with dynamic observing.
