Ultralight Dark Matter Could Explain Early Black Hole Formation
Blackholes are a fascinating class of object to study. We have learned significant amounts over the years but one of the outstanding mysteries remains; how there were supermassive black holes with millions or even billions of times the mass of the Sun present in the first billion years after the Big Bang. Our current models of stellar mass black hole evolution and mergers cannot explain their existence. A new paper suggests that ultralight dark matter particles, like axions may have done the trick and provides a mass range for expected particles.
