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 ...
The merging of galaxies is one critical path of galaxy evolution, yet the incidence rate of galaxy pairs and their impact on galaxies' physical properties are far from being definite.

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 ...
A team of astronomers propose a scenario in which galaxies with active cores may undergo a period of rapid star birth before shutting down completely. The research, conducted by astronomers from the University of Southampton, ...

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 ...
Using data from various spacecraft, astronomers have investigated an ultra-luminous X-ray pulsar known as NGC 7793 P13. The new study, published November 1 on the arXiv pre-print server, yields essential information regarding ...
Using data gathered by the Large Area Telescope onboard NASA's Fermi Gamma-ray Space Telescope and a stacking technique combining signals too weak to be observed on their own, researchers detected gamma rays from UFOs in ...
