Compact Object
Ultra-luminous X-ray Source (ULX)
An X-ray source brighter than any single stellar-mass binary should be.
Point-like X-ray sources in other galaxies with luminosities exceeding the Eddington limit for stellar-mass compact objects — possibly intermediate-mass black holes or hyper-accreting neutron stars.
