- 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.

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.

- Carnegie Mellon University-led team conducts most detailed cosmological simulation to date
06-28-2007 · EurekAlert!
Using a new computer model of galaxy formation, researchers have shown that growing black holes release a blast of energy that fundamentally regulates galaxy evolution and black hole growth itself. The model explains for the first time observed phenomena and promises to deliver deeper insights into our understanding of galaxy formation and the role of black holes throughout cosmic history. The results were generated by an international team of investigators.
