Using INTEGRAL and Swift spacecraft, European astronomers have observed an unidentified X-ray source known as XTE J1906+090. Results of the observational campaign, presented May 11 on the arXiv preprint server, suggest that ...
Using the Neutron Star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), an international team of astronomers has detected millihertz quasi-periodic oscillations from a low-mass X-ray binary ...
Astronomers have recently observed a low-mass X-ray binary known as IGR J17407−2808 with NuSTAR and XMM-Newton space telescopes. In result, they detected several fast X-ray flares from this source. The finding was reported ...
Astronomers using data from NASA's Chandra X-ray Observatory and other telescopes have identified a new threat to life on planets like Earth: a phase during which intense X-rays from exploded stars can affect planets over ...
