A Hungry Quasar Caught in the Act
May 31, 2001The VLT Secures Spectacular Image of Distant Gravitational Interaction
A new image of a distant quasar (the luminous core of an "active" galaxy) shows that it is engaged in a gravitational battle with its neighbouring galaxies. It also provides information on how supermassive black holes present in the center of quasars are fed.
Using the FORS2 multi-mode instrument at the ESO 8.2-m VLT KUEYEN telescope on Paranal (Chile), a team of German astronomers obtained a spectacular image of the close and complex environment of the distant quasar "HE 1013-2136", located some 10 billion light-years away.
The remarkable structures revealed in this photo lend support to the hypothesis that quasar activity is connected to gravitational interaction between galaxies, already at this early epoch of the Universe (about 5 billion years after the Big Bang).

Quasar Current Events and Quasar News RSSUniversity 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.
Merging galaxies create a binary quasar
Astronomers have found the first clear evidence of a binary quasar within a pair of actively merging galaxies.
Scientists observe super-massive black holes using Keck Observatory in Hawaii
An international team of scientists has observed four super-massive black holes at the center of galaxies, which may provide new information on how these central black hole systems operate.
Black Hole Caught Zapping Galaxy into Existence?
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.
Hubble repair mission carrying $70 million CU-Boulder instrument on track for May 11 launch
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
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.
NASA's Fermi Telescope Reveals Best-Ever View of Gamma-Ray Sky
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.
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).
Astronomers discover link between supermassive black holes and galaxy formation
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.
Mystery of missing hydrogen
Something vital is missing in the far distant reaches of the Universe: hydrogen - the raw material for stars, planets and possible life.

Baby Quasar Photorejuvenation Light Therapy by AdvanThera Beautiful, more clear skin begins from within. There's actually good science behind light therapy which shows how cell rejuvenation will create a more youthful appearance. The Baby Quasar uses four different wavelengths, between 600 and 1200 nm, both red and infrared, to stimulate maximum cellular activity. Other devices only use either one or two wavelengths. Using SequePulse Technology, our patent pending answer to the problems associated with using multiple wavelengths, the Baby Quasar is the perfect solution for someone trying to achieve more youthful look without having to spend both time and money on a Skincare Therapist. The Baby Quasar is very compact and requires no extra valuable tabletop space. Keep it safely tucked out of the way when not in use. |

Cosmological Enigmas: Pulsars, Quasars, and Other Deep-Space Questions by Mark Kidger (Author) The universe is big. Really big. And it gets bigger every day. In Cosmological Enigmas, Mark Kidger weaves together history, science, and science fiction to consider questions about the bigness of space and the strange objects that lie trembling at the edge of infinity. What are quasars, blazars, and gamma-ray bursters? Could we ever travel to the stars? Can we really expect aliens to contact us? From the profound (what evidence do we have to support the big bang theory?) to the bizarre (can there be more than one universe and, if so, how many dimensions does it possess?) to the everyday-yet-profound (why is the sky dark at night?), Kidger explains not only what we know but how we came to know it. Reflecting on how stars shine and what may lie beyond the edge of the universe,... |

Baby Blue Light Quasar Therapy System for Acne Treatment - Baby Blue LED Photo Rejuvenation Light Therapy Device by Baby Quasar Make acne sing the blues. Gorgeous, smoother, cleaner-looking skin is only a few minutes a day away. The Baby Blue light works by killing the acne-causing bacteria, P. Acne, and works well in treating inflammatory acne vulgaris that has not responded to other acne therapies. The P. Acne bacteria releases small molecules called Porphyrins. When Porphyrins are exposed to the Baby Blue's wavelengths of light, they produce free radicals that kill bacteria. Get rid of your harsh drying acne products. Gentle, natural, safe and painless, Baby Blue can be used on all skin types and all skin tones. While acne is not considered a serious health threat, severe acne can result in permanent scarring and can be a source of significant emotional distress. With regular and continued use, Baby Blue's... |

Quasars and Active Galactic Nuclei: An Introduction by Ajit K. Kembhavi (Author), Jayant V. Narlikar (Author) This book provides an up-to-date and comprehensive account of quasars and active galactic nuclei (AGN). The latest observations and theoretical models are combined in this clear, pedagogic textbook for advanced undergraduates and graduate students. Researchers will also find this wide-ranging and coherent review invaluable. Throughout, detailed derivations of important results are provided to ensure the book is self contained. And theories and models are critically compared with detailed and often puzzling observations from across the spectrum. We are led through all the key topics, including quasar surveys, continuum radiation, time variability, relativistic beaming, accretion disks, jet sidedness, gravitational lensing, unification and detailed, multi-wavelength studies of individual... |
