Luminous infrared galaxies or LIRGs are galaxies with luminosities, the measurement of brightness, above 10 11 L☉. They are also referred to as submillimeter galaxies (SMGs) through their normal method of detection.

亮紅外星系 或LIRGs是亮度量測上,具有紅外 光度 高於10 11 L☉ 的 星系。 通過正常的檢測方法,它們也被稱為次毫米星系 (SMGs)。 在比較光度時,亮紅外星系遠比 星暴星系 、 西佛星系 和 類星體 更為明亮。 紅外星系在 紅外線 中發射的能量比所有其它 波長 能量的總和還要多。 一個亮紅外星系的光度是 太陽 的1,000億倍。 光度在10 12 L☉ 以上的是極亮紅外星系(ULIRGs)。 超過10 13 L☉ 的星系是超亮紅外星系(HyLIRGs)。 那些超過10 14 L☉ 的星系是特亮紅外星 …
GOALS
The sample consists of nearly 180 Luminous Infrared Galaxies (LIRGs) with luminosities above 10 11 L ☉ as well as 22 Ultra-Luminous Infrared Galaxies (ULIRGs) with luminosities above 10 12 L ☉.
NASA’s Webb Will Explore the Cores of Merging Galaxies
2020年9月23日 · By using a range of telescopes on the ground and in space, the GOALS (Great Observatories All-sky LIRG Survey) research team has been analyzing galaxies like NGC 3256 from X-ray through radio wavelengths. NGC 3256 has a buried active nucleus, large-scale shocks from two powerful outflows, and a huge number of compact, bright star clusters.

2006年4月11日 · We investigate the role of the luminous infrared galaxy (LIRG) and ultra-luminous infrared galaxy (ULIRG) phases in the evolution of Ks-selected galaxies and, in particular, Extremely Red Galaxies (ERGs).
FIRST VIEWS OF A NEARBY LIRG: STAR FORMATION AND …
2010年11月15日 · We present a first look at the local luminous infrared galaxy (LIRG) IRAS 04296+2923. This barred spiral galaxy, overlooked because of its location behind the Taurus molecular cloud, is among the half dozen closest (D = 29 Mpc) LIRGs.
We study the morphology and star formation properties of 159 local luminous infrared galaxy (LIRG) using multi-color images from Data Release 2 (DR2) of the Sloan Digital Sky Survey (SDSS). The LIRGs are selected from a cross-correlation analysis between the …
