- 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.

- Largest, brightest supernova ever seen may be long-sought pair-instability supernova
05-07-2007 · EurekAlert!
UC Berkeley astronomers Nathan Smith and David Pooley report the most luminous supernova ever detected, the explosion of a super-massive star in a galaxy 250 million light years away. The scientists estimate the star was 150 times larger than our sun, and that it exploded via an entirely new mechanism never before observed. Unlike other massive supernovas, this so-called pair instability supernova left behind no black hole.

- 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.

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.

- 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.

- EuroNews looks at Integral
06-08-2007 · European Space Agency (ESA)
Integral is the first space observatory that can simultaneously observe objects in gamma rays, X-rays, and visible light. Its principal targets are gamma-ray bursts, powerful supernova explosions, and regions in the Universe thought to contain black holes. EuroNews talks to various scientists who are obtaining fascinating results from this laboratory.
