Newswise — Within the last two decades astronomers have discovered that black holes are ubiquitous in the Universe, that while stellar mass black holes populate galaxies by the millions, each galaxy also hosts a central supermassive black hole that is 10 million to 10 billion times the mass of the Sun. And when matter falls into these black holes they light up, some of them shining so brightly that they can be seen across the Universe. Researchers are trying to understand how the enormous amounts of energy that are emitted from the centers of these active galaxies can shape both their host galaxy as well as the intergalactic medium, an exploration that takes us back to shortly after the big bang when the Universe was only 5% of its current age.
