Primordial black holes are one of the strongest candidates for the Universe’s dark matter. In this scenario, their abundance would be large enough for...
The formation of ultrarare supermassive black holes, with masses over one billion solar masses, in the first billion years of the Universe is an open question...
If ‘stupendously large’ black holes, those with masses more than 100 billion times that of the Sun, exist in the Universe, they would provide a powerful...
In a new paper in the journal Physical Review Letters, an international team of theoretical physicists described a scenario for the formation of primordial...
Amir Siraj and Professor Avi Loeb from the Department of Astronomy at Harvard University have developed a new method to search for primordial black holes...
Using a technique called quasar microlensing, a team of astronomers at the University of Oklahoma has detected populations of free-floating planet-mass...
In a paper to be published in the journal Physical Review Letters (arXiv.org preprint), Professor George Fuller of the University of California, San Diego,...
