Research investigates variability of the ultraluminous X-ray source NGC 925 ULX-3

Astronomers from the California Institute of Technology (Caltech) and elsewhere have observed an ultraluminous X-ray source known as NGC 925 ULX-3 using NASA’s Swift and NuSTAR spacecraft, as well as ESA’s XMM-Newton satellite. Results of this observational campaign, published June 16 on arXiv.org, deliver important insights into variability behavior of this source.
