- 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.

- Astronomers discover new kind of black-hole explosion
12-20-2006 · EurekAlert!
Scientists have discovered what appears to be a new kind of cosmic explosion -- a "hybrid gamma-ray burst" -- which will be the subject of four articles to be published in the journal Nature on 21 December 2006. The scientists include four astrophysicists at Penn State University as well as others around the globe. The nature of the explosion is a puzzle in "virtually uncharted territory" for space scientists.

- Auger Observatory links highest-energy cosmic rays with violent black holes
11-08-2007 · EurekAlert!
Scientists of the Pierre Auger Collaboration, which includes New York University physics professor Glennys R. Farrar, have concluded that active galactic nuclei are the most likely candidate for the source of the highest-energy cosmic rays that hit Earth. Using the Pierre Auger Observatory in Argentina, a team of scientists from 17 countries found that the sources of the highest-energy particles are nearby galaxies that have active nuclei in their centers.

- Auger Observatory closes in on mystery, links highest-energy cosmic rays with violent black holes
11-08-2007 · EurekAlert!
The Pierre Auger Collaboration announced that active galactic nuclei are the most likely candidate for the source of the highest-energy cosmic rays that hit Earth. Using the Pierre Auger Observatory in Argentina, the team of scientists found that the sources of the highest-energy particles are not distributed uniformly across the sky. Instead, the Auger results link the origins of these mysterious particles to the locations of nearby galaxies that have active nuclei in their centers.

- Mystery cosmic explosions
12-20-2006 · EurekAlert!
Scientists have discovered what appears to be a new kind of cosmic explosion, the subject of four articles in this week's issue of Nature. They call the explosion a hybrid gamma-ray burst.As with other gamma-ray bursts, this hybrid burst is likely signalling the birth of a new black hole. It is unclear, however, what kind of object or objects exploded or merged to create the black hole or, perhaps, something even more bizarre.

- Michigan Tech helps solve mystery of cosmic rays
11-08-2007 · EurekAlert!
Using data-gathering equipment designed and tested at Michigan Technological University, scientists from 17 countries have identified Active Galactic Nuclei containing massive black holes as the most likely source of the highest-energy cosmic rays.

- UO plays key role in LIGO's new view of a cosmic event
01-03-2008 · EurekAlert!
An international team of physicists, including University of Oregon scientists, has concluded that last February's intense burst of gamma rays possibly coming from the Andromeda Galaxy lacked a gravitational wave. That absence, they say, rules out an initial interpretation that the burst came from merging neutron stars or black holes within Andromeda.

- Cosmic ray mystery solved?
11-08-2007 · EurekAlert!
The most energetic particles in the universe -- ultrahigh-energy cosmic rays -- likely come from supermassive black holes in the hearts of nearby active galaxies, says a study by scientists from nearly 90 research institutions worldwide, including the University of Utah.

- Biggest 'small' black hole discovered
10-19-2007 · EurekAlert!
Discovery of the largest example of a 'small' black hole -- one formed from the collapse of a single massive star at the end of its lifetime -- has led scientists to reevaluate of how black holes come into being, according to a report in Nature.
