A pair of astrophysicists at the Rochester Institute of Technology has found via simulations that some black holes might be traveling through space at nearly one-tenth the speed of light. In their study, reported in Physical ...
Using NASA's Chandra spacecraft, astronomers have performed detailed X-ray observations of a complex galaxy cluster known as Abell 119. Results of the observational campaign, published August 9 on the pre-print server arXiv, ...
The first direct detection of gravitational waves in 2015 has opened a new window on the universe, enabling in particular the observation of the merger of pairs of massive black holes. This young field of research has matured ...
