IRAS 17208-0014 is an ultraluminous infrared galaxy located about 617 million light-years from Earth in the southern constellation of Ophiuchus.[1] This is a well-studied galaxy hosting an hydroxyl (OH) megamaser,[2] first discovered by the Nancay radio telescope in 1985.[3] The redshift of the galaxy is (z) 0.0428 and it has a total infrared luminosity of 1012.4 Lʘ.[4]

Description

[edit]

IRAS 17208-0014 is categorized an advanced galaxy merger, a result of two disk galaxies colliding with one another. It is known to display two tidal tails that are protruding out from the galaxy by 20 kiloparsecs with a distorted central body.[5][6] The outer disk of the galaxy is disturbed and it has an extended nucleus when shown in near-infrared imaging bands, captured by the Hubble Space Telescope NICMOS camera.[7] The nucleus of the galaxy is compact and elongated along the position angle of 90° to 110°.[8] It is surrounded by both absorption features and condensations.[9] Observations also showed it has a buried active galactic nucleus (AGN) in the western disk of the galaxy.[4] The galaxy has a supermassive black hole located in the center, with a mass of 2.3 x 108 Mʘ based on a stellar velocity dispersion.[10]

IRAS 17208-0014 is described as a LINER. It has an X-ray luminosity measured as 1 x 1042 erg s-1 when observed by BeppoSAX.[11] There are several star clusters located within the inner region of the galaxy, said to be proto globular systems.[5] The galaxy is powered by intense starbursts with a star formation of 84 ± 13 Mʘ per year; fueled by a molecular gas reservoir.[12][13] Carbon monoxide line emission was also detected mainly originating from a molecular disk, found as spatially resolved and measuring a diameter of 2.7 x 1.8 kiloparsecs.[14][15] There is also evidence of a detached clump and three faint protrusions pushing the disk's emission out to 1.8 kiloparsecs. The mass of the molecular gas outflow is estimated to be 2 x 108 Mʘ.[15]

Three nuclear regions have been identified in IRAS 17208-0014, found aligned in a linear pattern along east to west. When imaged by matched resolution at 15 and 33 GHz frequencies by Very Large Array, they are combined into a larger region.[16] A deep study on the OH megamaser in IRAS 17208-0014 showed it having an area of around 170 x 110 parsecs in diameter and mainly found in two dominant regions.[17] The galaxy also shows HCO+ emission.[18]
