Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/sub-millimeter Array (ALMA), an international team of astronomers has observed a merging galaxy system known as B14-65666, dubbed "Big Three Dragons." ...
Using the Canada France Hawaii Telescope (CFHT), Chinese astronomers have performed multi-band observations of a merging dwarf galaxy known as VCC 322. Results of the observational campaign, presented March 4 on the preprint ...
When they are active, supermassive black holes play a crucial role in the way galaxies evolve. Until now, growth was thought to be triggered by the violent collision of two galaxies followed by their merger; however, new ...

Using the Karl G. Jansky Very Large Array (VLA) and the upgraded Giant Meter Radio Telescope (uGMRT), astronomers have conducted multi-wavelength observations of a galaxy merger remnant known as Mrk 212. Results of this observational ...
Astronomers have detected a new single radio relic in a low-mass merging galaxy cluster known as PLCK G200.9−28.2. The finding, presented Aug. 5 in a paper published on the arXiv pre-print server, could offer some hints ...
Black holes get a bad rap in popular culture for swallowing everything in their environments. In reality, stars, gas and dust can orbit black holes for long periods of time, until a major disruption pushes the material in.
