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).

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.

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.

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.

Chandra sees remarkable eclipse of black hole
04-12-2007 · EurekAlert!
A remarkable eclipse of a supermassive black hole and the hot gas disk around it has been observed with NASA's Chandra X-ray Observatory. This eclipse has allowed two key predictions about the effects of supermassive black holes to be tested.

RIT study predicts how fast a black hole can be booted from a galaxy
05-30-2007 · EurekAlert!
Scientists at RIT have discovered for the first time just how fast a supermassive black hole can be thrown from a galaxy when it merges with another black hole. The crucial factor in producing large "kicks" turns out to be the spin that the black holes carry prior to the merger.Manuela Campanelli and her team derived a formula that for the first time predicts the size and direction of the kick, or radiation recoil.

RIT study confirms supermassive black holes produce powerful galaxy-shaping winds
10-31-2007 · EurekAlert!
Supermassive black holes can produce powerful winds that shape a galaxy and determine their own growth, confirms a group of scientists from Rochester Institute of Technology. The RIT team has, for the first time, observed the vertical launch of rotating winds from glowing disks of gas, known as accretion disks, surrounding supermassive black holes in the centers of galaxies. The findings are reported in the Nov. 1 issue of Nature.
