An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a research about the growth mechanisms of supermassive black holes. A team of six Italian researchers led by Edward Pezzulli, a PhD student of the National Institute for Astrophysics (INAF) in Rome proposed a model that predicts that these objects can reach masses even billions of times the Sun’s not with a steady growth but with periodic “meals” that are very quick during whith they swallow huge amounts of materials.
