Ultraluminous X-ray sources in NGC 891 investigated by researchers

Researchers from the University of Chicago and Fordham University have conducted a long-term monitoring of three ultraluminous X-ray sources (ULXs) in the spiral galaxy NGC 891. Results of the research, presented in a paper published December 22 on arXiv.org, provide more insights into the properties of these sources and could help us better understand the nature of the host galaxy.
