Two articles currently being published in the journal “Monthly Notices of the Royal Astronomical Society” describe two researches on the connection between the development of supermassive black holes and the galaxies that host them. Two separate teams used observations from NASA’s Chandra X-ray Observatory and other telescopes, concluding that supermassive black holes grow faster than new stars form in their host galaxies. This contradicts previous models that suggested a growth proportional to star formation in the galaxies.
