Quasar SDSS J0 100+2802 with central black hole mass of 12 billion solar mass Discovered by The Scientists

The international team of scientists led by astronomers at the University of Beijing in China and the University of Arizona discovered the brightest quasar SDSS J0 100 + 2802 with the most massive black hole 12 billion solar masses.

The findings were published in the journal Nature on February 26, 2015 and Professor Xue-Bing Wu at Peking University is the lead author of the study.

Finding of Study Results:

• quasar SDSS J0100 + The 2802 called the luminosity of 420 trillion suns is at a distance of 12.8 million light years from Earth.
• The quasar is seven times brighter than the most distant known quasar is 13 billion years away
• The quasar goes back to the end of a major cosmic event known as the epoch of reionization. Reionization epoch is the cosmic dawn when light from the first generations of galaxies and quasars are thought to have ended the cosmic dark ages and transformed the universe as we see it today.

How was it discovered?

The quasar was discovered first by 2.4 meters Telescope Lijiang in Yunnan, China, which is the only one ever discovered by a 2-meter telescope at a distance quasar.

After the initial discovery, two telescopes of Large Binocular Telescope 8.4 meters and 6.5 meters multiple mirror telescope in southern Arizona did the heavy lifting in determining the distance and mass of the black hole.

Additional observations with the 6.5-meter Magellan Telescope at Las Campanas Observatory, Chile, and the 8.2-meter Gemini North Telescope on Mauna Kea, Hawaii, confirmed the results.

Importance of discovery

The quasar with super massive black hole provides a unique laboratory for the study of the whole mass and galaxy formation around more massive black holes in the early universe.
It will allow scientists to make unprecedented measurements of the contents of temperature, ionization state and the metal of the intergalactic medium in the era of reionization.
The discovery of this quasar marks an important step in understanding how quasars have evolved just 900 million years after the Big Bang is believed to have occurred 13.7 billion years ago.
About quasars
Discovered in 1963, quasars are the most powerful objects beyond the Milky Way.
They make huge amounts of energy through space as the supermassive black hole at its center suck in matter from its surroundings.
Until now, astronomers have discovered more than 200,000 quasars, with ages ranging from 0.7 million years after the Big Bang to the present.
