Mapelli and her collaborators first predicted that stellar collisions might lead to the formation of black holes in the mass gap about a year before the LIGO-Virgo observation was announced. They didn ...

This illustration shows the orbits of stars very close to Sagittarius A*, a supermassive black hole at the heart of the Milky Way. Despite their ancient ages, some stars orbiting the Milky Way’s ...

Densely packed, fast-moving stars at the Milky Way's center can collide with each other. New research uses simulations to explore the outcomes of these collisions. Some collisions are more like ...

A simulation showed black holes with masses between 100 and 10,000 times that of the sun could be born through a chaotic chain of stellar collisions. When you purchase through links on our site, we ...
