Black holes don’t always power gamma-ray bursts, new research shows

Gamma-ray bursts (GRBs) have been detected by satellites orbiting Earth as luminous flashes of the most energetic gamma-ray radiation lasting milliseconds to hundreds of seconds. These catastrophic blasts occur in distant galaxies, billions of light years from Earth. A sub-type of GRB known as a short-duration GRB starts life when…

Death of a star reveals midsize black hole lurking in a dwarf galaxy

Massive black holes (BHs) at the centers of massive galaxies are ubiquitous. However, their population in dwarf galaxies remains elusive. Identification of these systems has historically relied on detecting light emitted from accreting gaseous disks close to the black holes. Without this light, they are difficult to detect. An international…
