Using NASA's Chandra X-ray observatory, astronomers have spotted X-ray-emitting clumps being ejected with high velocities from the gamma-ray binary PSR B1259–63/LS 2883. The findings were presented in a paper published ...
Using a network of radio telescopes, European astronomers have investigated a decade-long transient known as FIRST J141918.9+394036. Results of this study, presented in a paper published February 18 on arXiv.org, provide ...
An international group of astronomers has detected an unusual nuclear transient in the nucleus of a weakly active galaxy. The new transient was identified by the OGLE-IV Transient Detection System and received designation ...
An international team of scientists, including astronomers from the Universities of Leicester, Bath and Warwick, have found evidence for the existence of a 'hot cocoon' of material enveloping a relativistic jet escaping a ...

Using Major Atmospheric Gamma-ray Imaging Cherenkov (MAGIC) telescopes, an international group of astronomers has detected a fast, very high-energy (VHE) flare from the blazar BL Lacertae. The finding is detailed in a paper ...
During the formation of a black hole, a bright burst of very energetic light in the form of gamma rays is produced, these events are called gamma ray bursts. The physics behind this phenomenon includes many of the least understood ...
