This year, however, a more terrestrial controversy echoed through both formal presentations and casual conversations at the […]

An artist’s depiction of a dwarf galaxy with a massive black hole highlighted. (Image: © Sophia Dagnello, NRAO/AUI/NSF) Astronomers have detected several supermassive black holes wandering through their dwarf host galaxies, providing new clues about how similar black holes evolved in the early universe. Using the National Science Foundation’s Karl G. […]

Two galaxies in the process of merging. Credit: NASA/ESA/Hubble When two galaxies merge, there are brief periods of stellar baby booms. A group of astronomers led by Lingyu Wang from SRON have now used a sample of over 200,000 galaxies to confirm that galaxy mergers are the driving force behind […]
