NYT Syndicate Some of the brightest objects in the universe " quasars
" are vanishing rapidly.
, the brightest objects in the universe, may have been responsible for the stopping of star-formation activity in some of the early massive galaxies in the universe, a new study suggests.
TEHRAN (FNA)- Astronomers linked extremely reddened quasars
to strong galactic outflowing winds that inhibit star formation in the early universe.
This new survey by the MUSE instrument on ESOs Very Large Telescope indicates that halos around quasars
are far more common than expected.
are considered the brightest and most puzzling objects in the universe.
Both theory and observations have pointed to the existence of a population of quasars
shrouded in a thick veil of dust and gas.
are believed to be the brightest and most energetic objects in the universe.
The researcher said that they used the Doppler shift for light to tell whether the gas in these quasars
is moving away from Earth or toward these distant black holes, which have a mass from millions to billions of times that of the Sun.
are quasi-stellar objects, from which light is extremely shifted toward the red [1-5].
are intense concentrations of energy believed to be generated by gas and dust swirling around massive black holes.
The most distant known quasars
show that some supermassive black holes formed when the universe was merely six percent of its current age, or about 700,000,000 years after the big bang.
, the most brilliant of cosmic fireworks, appear to shine forth from humdrum galaxies in the early universe and not the giant ones astronomers expected.
