SDSS J0100+2802 (SDSS J010013.02+280225.8) is a hyperluminous quasar located near the border of the constellations Pisces and Andromeda.It has a redshift of 6.30, [1] which corresponds to a distance of 12.8 billion light-years from Earth and was formed 900 million years after the Big Bang.
APM 08279+5255 was initially identified as a quasar in 1998 during an Automatic Plate Measuring Facility (APM) survey to find carbon stars in the galactic halo.The combination of its high redshift (z=3.87) and brightness (particularly in the infrared) made it the most luminous object yet seen in the universe.
Wallbox was founded in Barcelona, Spain by Enric Asunción and Eduard Castañeda in 2015 initially using the name Wall Box Chargers. In 2017, Wallbox came first in South Summit, a European startup competition. Wallbox then came in third place at the Startup World Cup in May 2018.
Two dishes are 4.5 m (15 ft) in diameter, while the third is 2 m (6 ft 7 in) in diameter. The solar arrays generate 1238 watts of power. It is believed that the Space Shuttle has been used to launch several satellites, possibly on missions STS-28 , STS-38 , and STS-53 .
The quasar's designation, S5, is from the Fifth Survey of Strong Radio Sources, 0014+81 was its coordinates in epoch B1950.0. It also has the other designation 6C B0014+8120, [ 1 ] from the Sixth Cambridge Survey of Radio Sources by the University of Cambridge .
The quasar shut down sometime in the last 70,000 years. [6] This revises current theories of quasar operation, as the quasar is quiescent, shutting down much faster than was thought possible, [7] and is much cooler than predicted. [5] The galaxy is currently 100 to 10,000 times dimmer than it was when its quasar burned into Hanny's Voorwerp. [8]
The object itself was detected in ESO images dating back to 1980, but its identification as a quasar occurred only several decades later. [2]An automated analysis of 2022 data from the European Space Agency's Gaia satellite did not confirm J0529-4351 as too bright to be a quasar, and suggested it was a 16th magnitude star with a 99.98% probability.
The quasar's luminosity is estimated at 4 × 10 13 solar luminosities. [1] This energy output is generated by a supermassive black hole estimated at 7.8 × 10 8 solar masses . [ 1 ] According to lead astronomer Bañados, [ 10 ] "This particular quasar is so bright that it will become a gold mine for follow-up studies and will be a crucial ...
