Colliding galaxies can trigger rapid star formation but also cause gas to be expelled. Astronomers used the James Webb Space ...
JWST and radio interferometry caught six massive galaxies colliding 12 billion years ago, while a young supermassive black ...
Far beyond the Milky Way, vast collections of galaxies continue to drift, gather and occasionally collide. One such region ...
Astronomers, using the Atacama Large Millimeter/submillimeter Array (ALMA), have confirmed the existence of a close quasar pair housed in a pair of merging galaxies seen when the universe was less ...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have discovered a close pair of quasars, which is a result of a distant massive galaxy merger. The detection of the quasar ...
Galaxy mergers are fundamental events in the hierarchical assembly of structure, in which two or more gravitationally bound systems coalesce to form a single, more massive galaxy. Such interactions ...
Active Galactic Nuclei (AGN) mark the energetic cores of galaxies where accretion onto supermassive black holes releases prodigious luminosities across the spectrum. These nuclei can exhibit ...
