4C +41.17
Radio galaxy in the constellation Auriga
From Wikipedia, the free encyclopedia
4C +41.17 is a radio galaxy located in the constellation Auriga. With the redshift of 3.79, it is located nearly 11.7 billion light-years from Earth.[1] At the time of its discovery in 1988,[2] it was one of the most distant galaxies ever seen.[3][4]

Characteristics
4C +41.17 is classified as a high redshift radio galaxy in the early universe with a presence of an ultra steep radio spectrum.[5][6][7] The source of the galaxy is powerful with its astrophysical jet driving shock waves that enhances the star formation.[8][9]
4C +41.17 is categorized as hyperluminous infrared galaxy.[10] The radio luminosity of this galaxy has been estimated as 29.18 x 1027.5 watts per hertz.[11] The total infrared luminosity has been found to be calculated as 1013 L☉[12] The central dust lane is shown to contain massive amounts of interstellar dust.[13]
An observation using the IRAM 30m telescope in Spain, has found presence of least two carbon oxide (CO) systems in 4C +41.17. One of the CO component is shown coinciding with the central core while the other is situated at the base of a cone-shaped region, southwest from the galaxy's nucleus. This evidence suggests it underwent a recent galaxy merger.[14] Extended X-ray emission has also been detected in addition.[15] A region of faint radio emission is shown elongating from the nuclear region by 5.3 kiloparsecs.[16] Deep spectropolarimetric observations with the W. M. Keck Telescope has also shown the ultraviolet emission of galaxy is mainly unpolarized.[17]
