After growth spurt, supermassive black holes spend half their lives veiled in dust
|
|

|
|
Supermassive black holes found at the centers of distant galaxies undergo huge growth spurts as a result of galactic collisions, according to a new study by astronomers at Yale University and the University of Hawaii. Their findings appear in the March 25 edition of Science Express. (2010-03-26)

University of Arizona astronomers discover most primitive supermassive black holes known
|
|

|
|
Astronomers have come across what appear to be two of the earliest and most primitive supermassive black holes known. The discovery, based largely on observations from NASA's Spitzer Space Telescope, will provide a better understanding of the roots of our universe, and how the very first black holes, galaxies and stars all came to be.

Black Hole Caught Zapping Galaxy into Existence?
|
|
09/09/2010 01:54 AM
|
|
Which come first, the supermassive black holes that frantically devour matter or the enormous galaxies where they reside? A brand new scenario has emerged from a recent set of outstanding observations of a black hole without a home: black holes may be "building" their own host galaxy. (2009-12-01)

|
|
A $70 million instrument designed by the University of Colorado at Boulder to probe the evolution of galaxies, stars and intergalactic matter from its perch on the orbiting Hubble Space Telescope is on schedule for its slated May 11 launch from Kennedy Space Center in Florida aboard NASA's space shuttle Atlantis.

Erratic Black Hole Regulates Itself
|
|
09/09/2010 01:54 AM
|
|
New results from NASA's Chandra X-ray Observatory have made a major advance in explaining how a special class of black holes may shut off the high-speed jets they produce. These results suggest that these black holes have a mechanism for regulating the rate at which they grow. (2009-03-26)

NASA's Fermi Telescope Reveals Best-Ever View of Gamma-Ray Sky
|
|
09/09/2010 01:54 AM
|
|
A new map combining nearly three months of data from NASA's Fermi Gamma-ray Space Telescope is giving astronomers an unprecedented look at the high-energy cosmos. To Fermi's eyes, the universe is ablaze with gamma rays from sources ranging from within the solar system to galaxies billions of light-years away. (2009-03-12)

Colors of Quasars Reveal a Dusty Universe
|
|

|
|
The vast expanses of intergalactic space appear to be filled with a haze of tiny, smoke-like "dust" particles that dim the light from distant objects and subtly change their colors, according to a team of astronomers from the Sloan Digital Sky Survey (SDSS-II). (2009-02-26)

Astronomers discover link between supermassive black holes and galaxy formation
|
|
09/09/2010 01:54 AM
|
|
A pair of astronomers from Texas and Germany have used a telescope at The University of Texas at Austin's McDonald Observatory together with Hubble Space Telescope and many other telescopes around the world to uncover new evidence that the largest, most massive galaxies in the universe and the supermassive black holes at their hearts grew together over time.

Colossal Black Holes Common in the Early Universe
|
|
09/09/2010 01:54 AM
|
|
Astronomers think that many - perhaps all - galaxies in the universe contain massive black holes at their centers. New observations with the Submillimeter Array now suggest that such colossal black holes were common even 12 billion years ago, when the universe was only 1.7 billion years old and galaxies were just beginning to form.
