Yale astronomers Grant Tremblay and Meredith Powell are part of the first research team to document a "changing look" quasar through a full cycle from dim to bright to dim again.
Shining a light on the dark Universe.
"The formation and evolution of the earliest light sources and structures in the universe is one of the greatest mysteries in astronomy," said Carnegie Institute's Eduardo Bañados. "Very bright quasars such as the 63 discovered in this study are the...
(Carnegie Institution for Science) Quasars are supermassive black holes that sit at the center of enormous galaxies, accreting matter. They shine so brightly that they are often referred to as beacons and are among the most-distant objects we can currently study. Show More Summary
The fuzzy experimental pop cut is the latest single from the LA psych wiz's third LP, 'Brunei,' out August 26 on Company Records.
ESPN’s Bill Walton is known for his many diverse interests, from the Grateful Dead to Temecula to volcanoes to quasars, so perhaps it’s not all that surprising that he’s now getting into Pokemon Go. Interest in the smartphone app isShow More Summary
"The most exciting possibility is that the missing photons are coming from some exotic new source, not galaxies or quasars at all," said Neal Katz of the University of Massachusetts at Amherst. For example, the mysterious dark matter, which holds...
Mini-jets of material ejected from a central supermassive black hole appear to be the culprits behind faint radio wave emissions in ‘radio-quiet’ quasars. A study of gravitationally-lensed images of four radio-quiet quasars has revealed the structure of these distant galaxies in unprecedented detail. Show More Summary
LIGO's results have opened a new window onto the universe. The advent of radio astronomy, for example, revealed the universe's most luminous objects in the form of quasars and pulsars. For Neil Turok of the Perimeter Institute the most exciting...
There are some great covers that don't match up with what actually happens in the comics, like pregnant Quasar or Captain America punching Hitler.
Nick Spencer breaks down the event's biggest twists, explaining what a new Quasar, Mariah Hill's situation and the Thunderbolts mean for Marvel's future.
A new QUASAR debuted this week. Spoiler alert: She's a lady! Here are ten more female heroes who inherited their codenames from male characters.
Avengers: Standoff! Assault on Pleasant Hill Omega introduces a new hero to the Marvel Universe, albeit one who's taking on a legacy that stretches back almost 40 years. The new Quasar is a female SHIELD agent named Avril Kincaid, and she'ss the creation of writer Nick Spencer and artists Daniel Acuña and Angel Unzueta. Continue reading…
Cutting edge simulations have revealed for the first time exactly how the supermassive black holes at the heart of quasars were formed.
Near the edge of the visible Universe are some of the brightest objects ever observed, known as quasars, which are believed to contain supermassive black holes of more than a billion times the mass of our Sun. Simulations by KentaroShow More Summary
Research led by Johns Hopkins University scientists has found new persuasive evidence that could help solve a longstanding mystery in astrophysics: Why did the pace of star formation in the universe slow down some 11 billion years ago? read more
An artists' illustration of a quasar. (Photo: NASA, and M. Weiss/Chandra X -ray Center) In the middle of almost every galaxy in the universe, there's a supermassive black hole. Around supermassive black holes, there are quasars—expansive discs of hot gas that are the brightest objects in the universe. Show More Summary
Quasar winds are crucial to galaxy formation, scientists say
New research led by astrophysicists has revealed the fastest winds ever seen at ultraviolet wavelengths near a supermassive black hole. "Quasar winds play an important role in galaxy formation," says Jesse Rogerson at York University. "When galaxies form, these winds...
Glauber Ballestero creates Cetus Quasar, a critical examination of three pillars of Western civilisation: capitalism, colonisation and modernity. Opening on 18 March at House of Egorn in Berlin, the young Cuban artist?s new series of work is based on video fragments by Buñuel?s The Milky Way, P.T. Show More Summary
