The Extremely Luminous Infrared Galaxy WISE J224607.57-052635.0, with a luminosity of 300 trillion suns was discovered by NASA's Wide-field Infrared Survey Explorer (WISE), and as of May 2015 is the most luminous galaxy found. The galaxy belongs to a new class of objects discovered by WISE, extremely luminous infrared galaxies, or ELIRGs.
FSC15307+3253 (or IRAS F15307+3252) [2] is an ultraluminous infrared galaxy (ULIRG), with a luminosity between 8 and 1000 μm of approximately 2 × 10 13 L ⊙, possibly the highest currently known. The "FSC" refers to Faint Source Catalogue , one of the source catalogs produced by the IRAS infrared survey mission.
IRAS 01003-2238 is the brightest galaxy of a small group. [4] It has two companions located 14.5 arcsec east and 18.5 arcsec southeast respectively. [5] It has an infrared luminosity of 10 12.2 L ʘ, [6] and a far-infrared luminosity of 1.9 x 10 12 L ʘ. [7]
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.
WISE J224607.57−052635.0 (or W2246−0526 for short) [3] is an extremely luminous infrared galaxy which, in 2015, was announced as the most luminous known galaxy in the observable universe. [3] [4] [5] The brightness of this galaxy is 350 trillion times [3] that of the Sun (349×10 12 L ☉ [1]).
The whole galaxy shines bright in infrared and it is characterised as a luminous infrared galaxy, with a total infrared luminosity (L IR) of 5 × 10 11 L⊙. [8] The James Webb Space Telescope (JWST) observed [9] the nucleus of the eastern galaxy in mid-infrared, revealing a northeastern and a southwestern core. The mid-infrared colors of these ...
