Decoding the Cosmic Remnants of Black Hole Feasts

An international team of astronomers has discovered a new way to study the behavior of active black holes when they consume matter. The team found that active black holes in the center of galaxies emit microwave and X-ray light in a similar manner, regardless of their appetite for surrounding galactic matter. This finding challenges the current understanding of how black holes eat and suggests that these black holes may have more similarities than previously thought. The study could provide new insights into how galaxies evolve and offers a new method for estimating black hole masses.
