Using data from NASA’s Swift and NuSTAR spacecraft, as well as from ESA’s XMM-Newton satellite, Indian astronomers have investigated spectral and temporal properties of an ultraluminous X-ray source (ULX) in the spiral galaxy NGC 55. The study, published November 12 on arXiv.org, sheds more light on the nature of this source.
