The ultraluminous X-ray source population is now broadly expected to be dominated by super-Eddington accretors comma thanks to the broadband spectroscopy provided by XMM and NuSTAR in combination comma the detection of X-ray pulsations from a growing subset of ULXs openParunambiguously confirming them as super-Eddington neutron starsclosePar and the detection of powerful outflows from a handful of systems. NGC5055 ULX1 is an extreme ULX openParLopenParX comma peakclosePar virgul 1e40 erg-sclosePar that has received very little observational attention to date.
