Measurements of the water vapor and of other molecules, such as carbon monoxide, suggest there is enough gas to feed the black hole until it grows to about six times its size.
However Physicist Ted Jacobson of the University of the Maryland in College Park, who suggested in 1999 that analogue radiation could be seen in the laboratory, says that the possibility of gleaning new insights about black holes from the sonic experiment remains «far fetched», for now.
To excite the voorwerp's glow, the black hole and its surrounding accretion disk, the active galactic nucleus, or AGN, should have had the brightness of about 2.5 trillion suns; its radio emission, however, suggested the AGN emitted the equivalent of a relatively paltry 25,000 suns.
This suggests there is something about jellyfish galaxies that makes them the ideal feeding ground for supermassive black holes, she says.
This supersized black hole is about 10 times heavier and brighter than others discovered from the same time period, says Wu, suggesting it grew extremely rapidly.
Long - term observations of IRAS F11119 +3257 suggest that winds near its central black hole blow outward at about 25 % the speed of light, the researchers report today in Nature.
An unusual object about 90 million light - years from Earth might be a supermassive black hole kicked out of its home galaxy during a collision with another galaxy, a new study suggests.
The characteristics of the surrounding stars suggest that although the magnetar's progenitor probably reached 40 solar masses at one point, it shed its mass so quickly that when the star exploded it fell under the 20 - solar - mass limit, thereby creating a magnetar instead of a black hole — and conforming to current theory about stellar evolution.
Recent speculation about the latest gravitational wave experiments suggested they may have seen a neutron star merger, but it's another black hole smashup
Previous work suggested that for black holes of this size — about 30 times the mass of the sun — there would be no bright flash, no hazy glow, no light to speak of.
To scientists, that suggested that the collision involved much less celestial stuff than a black - hole merger — that it was instead two neutron stars, each about one and a half times the mass of our sun.
The estimates are that tens of thousands to millions of these black holes could exist within our Galaxy, about three to thousands of times as many as previous studies have suggested.
