NICER observation list: Target ID 763102

Quasi-Periodic Eruptions (QPEs) are high-amplitude, repeating X-ray flashes from external galaxies that are possible probes of the interactions between orbiting bodies with massive black holes. Swift has recently discovered a new source that shows quasi-periodic X-ray eruptions, with a recurrence time of ~ 22 days, and likely accompanied by radio emission, revealing a new, and yet unexplored, time-scale for extragalactic nuclear transients. We request two sets of high-cadence NICER monitoring observations (2 visits of 250s for 70 days per set), and a simultaneous 5-day cadence monitoring with VLA during one of the NICER sets. Our goals are to 1) track the evolution of the eruption properties, i.e., amplitude, recurrence-time, and temperature, and ii) confirm the radio-X-ray correlation.
