Black Holes Where You'd Least Expect Them: Solving the Mass Gap Mystery

It was thought that the most massive stars explode completely, leaving no black holes, so none exist in the 50 to 130 solar mass range. New observations found several such anomalies with low spin. The reason lies in the nuclear reaction rate inside stars, which shifts the boundaries of what's possib

The Smoking Gun of Hierarchy: Black Holes Betray Their Ancestors

Using a flexible mixed population model, scientists discovered a striking coincidence: the mass distribution of high-spin black holes exactly matches the distribution of remnant masses from the low-spin subpopulation. This ‘smoking gun’ proves that rapidly spinning black holes arose from hierarchica
