These stars also probably formed in dense clusters, so it is likely that the black holes created on their deaths would have merged, giving rise to black holes of several thousand solar masses.

Furthermore, exceptionally fast growth can actually cause «choking,» where the radiation emitted during these super-Eddington episodes could disrupt and even stop the flow of mass onto the black hole, halting its growth.

When the Laser Interferometer Gravitational - Wave Observatory (LIGO) made the first detection of gravitational waves in 2015, for instance, scientists were able to trace them back to two colliding black holes weighing 36 and 29 solar masses, the lightweight cousins of the supermassive black holes that power quasars.

The study appears to vindicate predictions from theorists such as Mark Morris, an astrophysicist at the University of California, Los Angeles, who in 1993 penned a key paper predicting tens of thousands of stellar - mass black holes would form a disk around the galactic center.

Most black holes are thought to form when very massive stars — those with more than about 10 times the mass of sun — exhaust their nuclear fuel and begin to cool and therefore contract.

Microlensing by a 30 - solar - mass black hole should generate a rapid echo of a burst, making the black hole easier to detect.

The mass of the bulge is closely related to the mass of the black hole; the more massive the black hole the more energy is released into the surrounding galaxy in the form of powerful jets and X-ray emission.

Ordinary black holes form when individual stars collapse, and were thought to top out at about 15 times the mass of the sun.

But general relativity maintains that those black holes merged because their mass indented the fabric of space and time (SN: 10/17/15, p. 16).

«They are always created when a mass accelerates, like when an ice skater pirouettes or a pair of black holes rotate around each other.

«Even if only 1 percent of the mass in a filament takes part in the collapse, that's already 100,000 times the mass of the sun, a very good start to making one of these supermassive black holes,» Theuns says.

STEPHEN HAWKING famously predicted that black holes would «evaporate» away over time, emitting a form of radiation and slowly losing mass until they vanish.

Small black holes the size of stars and the supermassive variety are familiar, but until now there have only been tentative signs of intermediate - mass black holes.

Cardoso and colleagues calculated how long photons of given masses would take to sap a black hole's spin.

It doesn't necessarily make sense, said Stanek, professor of astronomy at Ohio State, that a massive star could undergo a supernova — a process which entails blowing off much of its outer layers — and still have enough mass left over to form a massive black hole on the scale of those that LIGO detected.

Cardoso counters that this apparent mass only affects things at a subatomic level — the photon's real mass is what matters at the scale of the black hole.
