Astronomers have detected transient rhythmic oscillations in the gamma-ray emission from the blazar Markarian 501. The discovery, reported in a paper published August 18 on the arXiv pre-print server could be helpful in improving ...
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 ...
Scientists from the RIKEN Cluster for Pioneering Research and collaborators have used simulations to show that the photons emitted by long gamma-ray bursts, among the most energetic events to take place in the universe, originate ...

(Phys.org)—A team of astronomers led by Yogesh Maan of the Netherlands Institute for Radio Astronomy (ASTRON) has discovered radio emission from the gamma-ray pulsar known as J1732−3131. The study, presented in a paper ...
(Phys.org) —The team of scientists associated with the Fermi Gamma-ray Space Telescope mission has published a catalog of gamma-ray sources at energies above 10 GeV. In their paper uploaded to the preprint server arXiv, ...
Galaxies, including our Milky Way, host supermassive black holes in their centers, and their masses are millions to billions of times larger than the sun. Some supermassive black holes launch fast-moving plasma outflows which ...
