Peculiar ionized structures, supernova remnants detected around an ultraluminous X-ray source

Using the Very Large Telescope (VLT), French astronomers have performed spectroscopic observations of an ultraluminous X-ray source known as NGC 1313 X–1. The observational campaign resulted in the detection of a shocked-ionized bubble, an X-ray photoionized nebula and also two supernova remnants around this source. The findings were published January 23 on arXiv.org.
