Chandra And XMM-Newton Show Direct Measurement Of Distant Black Hole's Spin
2014-03-06 08:15:43

[ Watch the Video: Measuring a Distant Black Hole's Spin ] NASA Astronomers have used NASA's Chandra X-ray Observatory and the European Space Agency's (ESA's) XMM-Newton to show a supermassive black hole six billion light years from Earth is spinning extremely rapidly. This first direct measurement of the spin of such a distant black hole is an important advance for understanding how black holes grow over time. Black holes are defined by just two simple characteristics: mass and...

April Flowers for redOrbit.com - Your Universe Online A new superpowered small black hole, called MQ1, has been discovered by a team of Australian and American astronomers who were studying nearby galaxy M83. MQ1 is the first object of its kind to be studied in this much detail. Previously, astronomers have found a few compact objects as powerful as MQ1, but they have been unable to calculate the size of the black hole contained within until now. Using multiple telescopes, the team's...

Active Supermassive Black Holes Discovered In Two Merging Galaxies

[ Watch the Video: Galaxy Mergers And Supermassive Black Holes ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers publishing a paper in the Astrophysical Journal say they have found two merging galaxies have active supermassive black holes. The team conducted infrared observations of the merging galaxies by using the Subaru Telescope. They found that at least one of the supermassive black holes almost always becomes active and luminous by accreting a large amount of...

[ Watch The Video: Zooming In On The Lagoon Nebula ] Brett Smith for redOrbit.com - Your Universe Online The European Space Observatory (ESO) is currently in the midst of conducting eleven public surveys of the sky using telescopes at its facility in Chile, and scientists have just released images from the project of the Lagoon Nebula. Located approximately 5,000 light years from Earth in the constellation of Sagittarius, the Lagoon Nebula is a giant cloud 100 light-years across that...

redOrbit Staff & Wire Reports - Your Universe Online A distant quasar discovered by astronomers working at Hawaii’s WM Keck Observatory has for the first time revealed part of the filament networks believed to connect galaxies in a cosmic web, according to research published Sunday in the journal Nature. Using the observatory’s 10-meter Keck I Telescope, a team of researchers including first author Sebastiano Cantalupo, a postdoctoral fellow at the University of California,...

[ Watch the Video: Turn About Is Fair Play - Black Hole Caught Orbiting A Star ] John P. Millis, PhD for redOrbit.com - Your Universe Online Black holes, by their very definition, are difficult to find. Their density is so great, that light cannot be given off directly, and photons that stray too close are absorbed into the gravitational well. So researchers have to rely on indirect evidence that a black hole is present by searching for their effects on other nearby objects....

Quasars Illuminate Swirling Clouds Around Galaxies
2014-01-09 08:49:42

University of Illinois at Urbana-Champaign A new study of light from quasars has provided astronomers with illuminating insights into the swirling clouds of gas that form stars and galaxies, proving that the clouds can shift and change much more quickly than previously thought. Led by University of Illinois at Urbana-Champaign astronomy professor Robert J. Brunner and former graduate student Troy Hacker (now with the U.S. Air Force), the astronomers published their findings in the...

Large-Scale Structure of the Cosmos -- Stars are organised into galaxies which in turn appear to form clusters and superclusters, separated by voids. Prior to 1989 it was commonly assumed that the superclusters were the largest structures in existence, and that they were distributed more-or-less uniformly throughout the universe in every direction. However, in 1989, Margaret Geller and John Huchra discovered the "Great Wall", a sheet of galaxies more than 500 million light years long...

Supermassive Black Hole -- A Supermassive black hole is a black hole with a mass in the range of millions or billions solar masses. A supermassive black hole has some interesting properties differing from his low-mass cousins: -- The average density of a supermassive black hole can be very low, and actually can be lower than water's density. This happens because the black hole diameter increases linearly with mass, and consequently density drops much faster. -- Strong tidal...

Redshift -- Redshift is the phenomenon that the frequency of light when observed, under certain circumstances, can be lower than the frequency of light when it was emitted at the source. This usually occurs when the source moves away from the observer, as in the Doppler effect. More specifically, the term redshift is used for the observation that the spectrum of light emitted by distant galaxies is shifted to lower frequencies (towards the red end of the spectrum, hence the name) when...

Microquasar -- Microquasars are smaller cousins of quasars. They are named after quasars, as they have some common characteristics: strong and variable radio emission often seen as radio jets, and an accretion disk surrounding a black hole. In quasars, the black hole is supermassive (millions of solar masses) as in microquasars, the black hole mass is a few solar masses. In microquasars, the accreted mass comes from a normal star and the accretion disk is very luminous in optical regions...

Gravitational Lens -- A gravitational lens is formed when the light from a very distant, bright object (such as a quasar) is "bent" around a massive object (such as a massive galaxy) between the bright object and the viewer. The process is known as gravitational lensing, and was one of the predictions made by Einstein's general relativity. Description In a gravitational lens, the gravity from the massive object bends light as a lens might. As a result, the path of the light from a...
