Then Wing, as part of his dissertation work, compared those suspected clusters to visual-light images from the archives of the Sloan Digital Sky Survey
. The most exciting candidates, says Blanton, are those for which the Sloan pictures look dark, hinting that the radio signal could be coming from a cluster so distant that the Sloan Survey telescope can't see it at all.
He recently retired from New Mexico State University as a telescope operator for the Sloan Digital Sky Survey
The Baryon Oscillation Spectroscopic Survey (BOSS), the largest component of the third Sloan Digital Sky Survey
(SDSS-III), pioneered the use of quasars to map density variations in intergalactic gas at high redshifts, tracing the structure of the young universe.
Teams from Lawrence Berkeley National Laboratory in California and Fermi National Accelerator Laboratory in Batavia, Ill., produced surveys with similar results using images taken by the Sloan Digital Sky Survey
from 2000 to 2009.
Sloan Digital Sky Survey
(SDSS) provided the data to identify galaxies which were a result of two smaller galaxies colliding.
The astronomers found about 12,000 blips that matched up with galaxies listed in a Sloan Digital Sky Survey
To create a comprehensive asteroid map, the researchers first analyzed data from the Sloan Digital Sky Survey
, which uses a large telescope in New Mexico to take in spectral images of hundreds of thousands of galaxies.
Spectra of the galaxies taken by the Sloan Digital Sky Survey
indicate that the greenish hue comes from the glow of ionized oxygen gas heated by newborn stars, says Carolin Cardamone of Yale University.
First found as part of the Sloan Digital Sky Survey
in 2016, the dwarf SFG was studied in detail by astronomers from the Ukrainian National Academy of Sciences (UNAS) and the University of Virginia (UVA), who used the Large Binocular Telescope in Arizona.
The work by Hamann, combined with previous research by Hamann and others, describes the discovery of the new population of extremely red quasars detected in the Baryon Oscillation Sky Survey (BOSS) of the Sloan Digital Sky Survey
But a second look at Sloan Digital Sky Survey
(SDSS) observations suggests that the disk actually has four ripples, with two more lying between us and the Monoceros Ring.
The discovery came as Palladino, working under the supervision of Kelly Holley-Bockelmann, assistant professor of astronomy at Vanderbilt, was mapping the Milky Way by calculating the orbits of Sun-like stars in the Sloan Digital Sky Survey
, a massive census of the stars and galaxies in a region covering nearly one quarter of the sky.
