Black hole winds are no longer as they used to be
During the first billion years of the universe, winds blown by supermassive black holes at the centers of galaxies were much more frequent and more powerful than those observed in today’s galaxies, some 13 billion years later. Such winds were so mighty that they slowed down the growth of the supermassive black holes from which they originate. These are the results of a study led by three researchers from the Italian National Institute for Astrophysics (INAF) in Trieste, published today in the journal Nature.
