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.

Astronomers from the California Institute of Technology (Caltech) have investigated a persistent radio source known as QRS121102 that is associated with the fast radio burst FRB 121102. Results of the study, published January ...
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 ...
Using ESA's XMM-Newton spacecraft, an international team of astronomers has conducted X-ray observations of the most distant known gravitationally lensed quasar—J0439+1634. Results of the study, published December 20 on ...
Using NASA's Fermi spacecraft, researchers from the Indian Institute of Astrophysics in Bangalore, India, have conducted a gamma-ray flux and spectral variability study of a blazar known as Ton 599, during its recent flaring ...
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, ...
