Unusual supernovae may reveal intermediate-mass black holes in globular clusters

01-29-2008 · EurekAlert!

A strange and violent fate awaits a white dwarf star that wanders too close to a moderately massive black hole. According to a new study, the black hole's gravitational pull on the white dwarf would cause tidal forces sufficient to disrupt the stellar remnant and reignite nuclear burning in it, giving rise to a supernova explosion with an unusual appearance.

Black hole boldly goes where no black hole has gone before
01-03-2007 · European Space Agency (ESA)
Astronomers have found a black hole where few thought they could ever exist, inside a globular star cluster. The finding has broad implications for the dynamics of stars clusters and also for the existence of a still-speculative new class of black holes called 'intermediate-mass' black holes.

Scientists reveal how supermassive black holes bind into pairs during galaxy mergers
06-07-2007 · EurekAlert!
Now, using supercomputers to simulate galaxy mergers, scientists at Stanford and elsewhere have seen the formation of a new type of structure-a central disk of gas that can be from a hundred to a few thousand light years wide and from a few hundred million to a billion solar masses. They report the first simulated formation of a supermassive black hole (SMBH) pair in the June 7 edition of Science Express, an online version of Science magazine.

New technique for 'weighing' black holes

Hubble yields direct proof of stellar sorting in a globular cluster
10-24-2006 · EurekAlert!
A seven-year study with the NASA/ESA Hubble Space Telescope has provided astronomers with the best observational evidence yet that globular clusters sort out stars according to their mass. Heavier stars slow down and sink to the cluster's core, while lighter stars pick up speed and move across the cluster to its periphery. This process, called "mass segregation," has long been suspected for globular star clusters, but has never before been directly seen in action.

New technology enables astronomers to detect two supermassive black holes in colliding galaxies
05-17-2007 · EurekAlert!
Astronomers, including UCR’s Gabriela Canalizo, have used powerful adaptive optics technology at the W.M. Keck Observatory in Hawai‘i to reveal the precise locations and environments of a pair of supermassive black holes at the center of an ongoing collision between two galaxies 300 million light-years away. Each of the black holes resides at the center of a rotating disk of stars and is surrounded by a cloud of young star clusters formed in the merger.

No matter their size black holes 'feed' in the same way
12-06-2006 · EurekAlert!
Research by UK astronomers, published today in Nature (7th December 2006) reveals that the processes at work in black holes of all sizes are the same and that supermassive black holes are simply scaled up versions of small Galactic black holes.For many years astronomers have been trying to understand the similarities between stellar-mass sized Galactic black hole systems and the supermassive black holes in active galactic nuclei (AGN).

Chandra catches 'piranha' black holes
07-24-2007 · EurekAlert!
Supermassive black holes have been discovered to grow more rapidly in young galaxy clusters, according to new results from NASA's Chandra X-ray Observatory. These "fast-track" supermassive black holes can have a big influence on the galaxies and clusters that they live in.

Ultrafast Star Escapes Black Hole
10-13-2006 · ScienceDaily
At last astronomers have a method to accurately measure the speed of stars within a galaxy containing a black hole. Dutch researcher Alessia Gualandris developed the algorithm for this in cooperation with the Astronomical Institute "Anton Pannekoek" and the Amsterdam Informatics Institute. The outcomes of this groundbreaking research provide convincing evidence for the relationship between galactic nuclei, heavy black holes and ultrafast stars in the Milky Way.
