Italian astronomers have performed X-ray observations of the massive galaxy cluster ClG-J104803.7+313843, using ESA's XMM-Newton spacecraft. Results of the observational campaign, presented November 26 on arXiv.org, shed ...
Astronomers have a model of how galaxy cluster collisions go through different stages, taking on various shapes. A blunt body shape turns into a sharp cone, which turns into a tongue-like shape. The first and last have been ...

Using data from NASA's Chandra X-ray Observatory, Indian astronomers have inspected a nearby galaxy cluster known as Abell 1569. Results of the study, published October 29 on arXiv.org, deliver important insights into the ...
When two galaxies collide, the supermassive black holes at their cores release a devastating gravitational "kick," similar to the recoil from a shotgun. New research led by CU Boulder suggests that this kick may be so powerful ...
