A new study using VLT observations verifies the long-standing prediction that accretion discs emit intensely blue radiation. The researchers used polarised light from six quasars to uncover the buried light from the discs, vindicating the standard picture of these discs.
A team from Rochester Institute of Technology has confirmed that supermassive black holes launch rotating winds that shape galaxies and regulate their growth. The findings, reported in Nature, provide direct observational confirmation of a long-standing theory about quasar winds.
Researchers at Cornell University have found clear bumps in infrared emissions at 10 and 18 microns in five type 1 AGNs, confirming the existence of silicate dust and supporting the unified theory. This evidence may provide insights into the inner temperature of dusty tori and shed light on the structure of active galactic nuclei.
Researchers watched the inner regions of an accretion disk, just miles from a neutron star's surface, change its structure in real-time. The observation provides new insight into the flow of a neutron star's accretion disk and could help study black holes and distant quasars.
Caltech researchers use magnetic forces to create jet-like structures in a hydrogen plasma experiment, shedding light on the formation of astrophysical jets. The study involves running high electrical currents through a cylindrical metal chamber, producing spiral-shaped plumes similar to those observed in space.
Researchers use theoretical calculation to understand merger process, predicting brief brightness increase and high-speed gas outflow. The study sheds light on quasar activation following super-massive black hole mergers, a phenomenon not yet fully understood.
A study by University of Warwick researchers found that English football games are characterized by fewer high-scoring matches compared to the rest of the world. In contrast, top division matches globally exhibit a much higher frequency of high scores, suggesting a significant difference in the level of excitement between the two.
Future orbiting X-ray telescopes will detect iron emissions in accretion disks around giant black holes, confirming their spin rates. This new telescope system could reveal the variability of X-ray emissions and test Einstein's theories on general relativity.
Astronomers observe regular eruptions of hot gas every 45-90 minutes, chaotic system behaving like a giant particle collider. Researchers discover new class of flares made up of synchrotron radiation and plasma bubbles.
