Description
Ultraluminous X-ray sources are powerful extra-nuclear sources of X-rays found in nearby galaxies, which in most cases are believed to be powered by super-Eddington accretion onto neutron stars and black holes. While most known ULXs are persistent sources, recently some new sources have been found that appear to come and go. I will present results from a systematic search for these transient ULXs in Swift/XRT data, what they might tell us about super-Eddington accretion, and discuss the prospects for SRG surveys.
