NICER observation list: Target ID 561403

Abstract

Quasi-Periodic Eruptions (QPEs) are extreme soft X-ray bursts of unknown nature recurring on the timescale of hours. So far only four such sources have been found. One of these, eRO-QPE1, can only be monitored with NICER. We want to know i) if QPEs are still ongoing and if the period has changed since discovery, ii) if there is evidence of a decrease, resonances and/or possible modulations, iii) the physical cause of these bursts. To achieve this, we ask for 4 sets of observations, each with a baseline of 7 days with 14 visits per days, each visit with exposure of 250s (for a total of 98ks).
