Astronomers Play Hide-and-Seek with Supermassive Black Holes
Supermassive black holes are millions of times bigger than the sun and “feast” on their surroundings. But despite their size, the galactic giants can often evade detection. In a forthcoming paper in the Astrophysical Journal, researchers describe five different supermassive black holes. Astronomer George Lansbury, lead author on the study, discusses why the super-sized black holes are so difficult to find and what they can tell us about the evolution of the universe.
George Lansbury is a postgraduate student at the Centre for Extragalactic Astronomy at Durham University in Durham, England.
