Polarimetry of Ultraluminous X-ray sources

Ultraluminous X-ray sources (ULXs) are non-nuclear X-ray emitters exceeding the Eddington luminosity, offering key insights into extreme accretion physics. Their origin is attributed to either sub-Eddington accretion onto intermediate-mass black holes (IMBHs) or supercritical accretion onto stellar-mass compact objects in binary systems.

Deep Very Long Baseline Interferometry Constraints on Compact Radio Cores in Four Ultraluminous X-Ray Sources

The Astrophysical Journal
We present high-sensitivity very long baseline interferometry (VLBI) observations of four ultraluminous X-ray sources (ULXs): Holmberg II X-1, IC 342 X-1, NGC 6946 X-1, and NGC 925 X-1.
