The most luminous serendipitous ULXs in 4XMM-DR9
Abstract
We identified a group of extreme ULX candidates cross-matching 4XMM-DR9with the HyperLeda database. We aim at obtaining better X-ray spectra andpositions for 6 of the brightest sources that will help us to confirmtheir nature, super-critical accreting object, intermediate-mass blackhole or background AGN.
