Why Is This Quasar Running Away From Such a Handsome Galaxy?

last monthTechnology / Gadgets : Gizmodo

We don’t understand quasars all that well, but are pretty certain that these incredibly bright lights belong in the centers of galaxies. So it looked a little weird when astronomers spotted quasar 3C 186 thirty six thousand light years away from the center of its galaxy, seemingly trying to escape. Read more...

Astronomers observe early stages of Milky Way-like galaxies in distant universe

For decades, astronomers have found distant galaxies by detecting the characteristic way their gas absorbs light from a bright quasar in the background. But efforts to observe the light emitted by these same galaxies have mostly been unsuccessful. Show More Summary

Astronomers discover 16 new high-redshift quasars

(—Using a new color selection technique, astronomers have detected 16 new luminous, high-redshift quasars. The discovery could be very important for understanding of the early universe, as such high-redshift, quasi-stellar objects...Show More Summary

Why the discovery of a bevy of quasars will boost efforts to understand galaxies' origins

Late last year, an international team including researchers from the Kavli Institute for Astronomy and Astrophysics (KIAA) at Peking University announced the discovery of more than 60 extremely distant quasars, nearly doubling the number known to science - and thus providing dozens of new opportunities to look deep into our universe's history.

"Which Came First Galaxies or the Black Holes at their Core?" --60 Newly Discovered Quasars Powered by Gargantuan Black Holes May Hold the Clue

Quasars, stupendously bright regions in the cores of galaxies, powered by gargantuan black holes, will deepen our understanding of why nearly all galaxies have supermassive black holes at their cores, begging the chicken-or-the-egg question of which came first, the galaxies...        

Why the discovery of a bevy of quasars will boost efforts to understand galaxies' origins

(The Kavli Foundation) Three astrophysicists, including a member of the team that recently announced a huge find of extremely distant quasars, explain how these "lighthouses" of the universe will shed some much-needed light on a formative period of cosmic history.

Flickering Quasars Used To Measure Universe Expansion | Video

Using gravitational lensing, astronomers have imaged distant quasars with the Hubble Space Telescope. They used the imagery to determine that the Universe is expanding quicker that previously thought.

The Universe Is Expanding Faster Than Expected, But New Results Raise More Questions

3 months agoTechnology : Forbes: Tech

New observations of lensed quasars show the Universe is expanding faster than expected. But these results raise questions about the assumptions of our cosmological models.

How fast is the universe expanding? Quasars provide an answer

(Ecole Polytechnique Fédérale de Lausanne) The H0LiCOW collaboration, a cosmology project led by EPFL and Max Planck Institute and regrouping several research organizations in the world has made a new measurement of the Hubble constant, which indicates how fast the universe is expanding.

Mysterious faint object detected in the vicinity of a quadruply lensed quasar

(—Astronomers have spotted a mysterious faint object in the vicinity of a quadruply lensed quasar designated MG 0414+0534. The object, which was discovered using the Atacama Large Millimeter/submillimeter Array (ALMA), appears to be a dusty, dark dwarf galaxy or an ultra-diffuse galaxy (UDG). The findings were presented January 19 in a paper published on

Even over billions and billions of years, the laws of physics were exactly the same.

‘Youngblood’ And ‘Brigade’ Could Be Joining Other Comic Book Movies In The Near Future

4 months agoHumor / odd : Nerd Bastards

A long time ago, when Costco used to sell comic books in sealed packages ranging from X-Men to Thor to Batman and even Quasar. Who the hell is Quasar? Exactly. Also included in some of those packages were some smaller press comics from a company by the name of Image. Their titles included Youngblood, Brigade, […]

High-redshift quasar discovered by Pan-STARRS

(—A new luminous high-redshift quasar has been detected by one of the telescopes of the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS). The newly discovered quasi-stellar object received designation PSO J006.1240+39.2219 and is the seventh highest redshift quasar known to date. The findings are presented in a paper published Dec. 19 on

Finding the unknowns in the universe

What have pulsars, quasars, dark matter and dark energy got in common? Answer: each of them took the discoverer by surprise. While much of science advances carefully and methodically, the majority of truly spectacular discoveries in astronomy are unexpected.

'A Cosmic Miracle' --"Behemoth Black Holes of the Early Galaxies Emerged From a Single Central Supermassive Star"

"The quasars observed in the early universe resemble giant babies in a delivery room full of normal infants," observed Avi Loeb of the Harvard–Smithsonian Center for Astrophysics. "One is left wondering: what is special about the environment that nurtured these...        

Light from Ancient Quasars Confirm the Laws of Physics Constant Throughout the Cosmos

Are the laws of nature constant throughout the universe, or do they change depending on where one is? As far as we can tell, the fundamental laws that govern our understanding of reality, including the four fundamental forces — the....

Do extremely reddened quasars extinguish star formation?

Galaxies formed and grew billions of years ago by accumulating gas from their surroundings, or colliding and merging with other young galaxies. These early stages of galaxy assembly are believed to be accompanied by episodes of rapid star formation, known as starbursts, and rapid growth of a single super-massive black hole in the galactic centers.

Do extremely reddened quasars extinguish star formation?

(University of California - Riverside) New research, led by Frederick Hamann, a professor at the Department of Physics and Astronomy at University of California, Riverside, describes the discovery of a unique new population of extremely red quasars. The findings were recently published in the journal the Monthly Notices of the Royal Astronomical Society.

Ancient Quasars Cast Light on Mysteries of the Cosmic Web

An international collaboration of astronomers, led by a group at the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland, has used the unrivalled observing power of MUSE on the Very Large Telescope (VLT) at ESO's Paranal Observatory to study...
