SDSS1133
Near the galaxy at a distance of about 800 pc, there is a bright X-ray source SDSS J113323.97 + 550415.8 (SDSS1133) in orbit around Markaryan 177. The source has been stable for several decades, from the 1950s to the 2000s, the radiation generation area has a size of about 40 pc . The object may be a supermassive black hole ejected from the galaxy interacting with the Markaryan 177 galaxy.
According to other theories, an x-ray source can be a bright blue variable , which recently, in the early 2000s, experienced a supernova outburst, with periodic emissions in the previous 50 years. [7] [9] [10]
