NICER observation list: Target ID 760802

Abstract

Galaxies emitting X-ray Quasi-Periodic Eruptions (QPEs) from their center represent the new frontier of X-ray variable accretion onto massive black holes. To date, only 4 bona-fide QPE sources are publicly known. We aim to increase this number by following up 3 new QPE candidates selected based on their X-ray variability in the eROSITA all-sky surveys data. We designed the ideal NICER monitoring to confirm their putative nature as repeating erupters, which amounts to a total of only 69ks in total.
