Fernanda Ferreira | School of Science | MITNovember 20, 2019 From the very beginning, it was clear that the Phoenix cluster was different from other galaxy clusters. When assistant professor of physics Michael McDonald looked at the first image […]

Astronomers use giant galaxy cluster as X-ray magnifying lens

New lens technique spots tiny dwarf galaxy in the first, super-energetic stages of star formation. Jennifer Chu | MIT News OfficeOctober 14, 2019 Astronomers at MIT and elsewhere have used a massive cluster of galaxies as an X-ray magnifying glass to peer back in time, to nearly 9.4 billion years ago. In the process, they […]

Black holes stunt growth of dwarf galaxies

OCTOBER 12, 2019 by¬†University of California – Riverside Astronomers at the University of California, Riverside, have discovered that powerful winds driven by supermassive black holes in the centers of dwarf galaxies have a significant impact on the evolution of these galaxies by suppressing star formation. Dwarf galaxies are small galaxies that contain between 100 million to a […]
