Using the Hard X-ray Modulation Telescope (HXMT), astronomers from Shanghai Astronomical Observatory in China have detected a low frequency, quasi-periodic oscillation in a black hole high mass X-ray binary known as Cygnus ...
Using NASA's Chandra X-ray Observatory and ESA's (European Space Agency's) XMM-Newton, astronomers are exploring whether nearby stars could host habitable exoplanets, based on whether they emit radiation that could destroy ...

Using India's AstroSat spacecraft, astronomers have performed broadband timing and spectral observations of an ultra-luminous X-ray (ULX) pulsar known as Swift J0243.6+6124. Results of this observational campaign, presented ...
Using NASA's Chandra X-ray observatory and Australia Telescope Compact Array (ATCA), astronomers have investigated a pulsar wind nebula, dubbed "the Goose," powered by a young pulsar known as PSR J1016–5857. Results of ...
Ray tracing is simple to explain at one level: "We all do it all day long: That's how you navigate the world visually," Gene Tracy explains. "The fact that I know that you're sitting there and not over there is because the ...

Chinese astronomers have conducted a gamma-ray and optical variability analysis of the blazar 3FGL J0449.4-4350. The new research, presented in a paper published March 25 on arXiv.org, reports the detection of possible quasi-periodic ...
Researchers from the U.S. Naval Observatory and elsewhere have performed simultaneous observations of an active galactic nucleus (AGN) in the galaxy NGC 2992 using the Very Long Baseline Array (VLBA) and NASA's Swift spacecraft. ...
