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.

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 ☉.

亮红外星系（LIRG）是定义特征在 电磁频谱 的 远红外线 上发射出的能量比太阳亮上1011的一种 星系。 更明亮的天体，在远红外线的辐射高于太阳亮度10倍的就称为极亮红外星系（ULIRG）。 再明亮的发光系统，在远红外线的辐射高于太阳亮度10倍的就称为就称为特亮红外星系（HLIRG）。 大部分的亮红外星系和极亮红外星系辐射出的光90%都是 红外线。 多数的亮红外星系和全部的极亮红外星系都显示有新的或持续的交互作用和瓦解的迹象，许多也都是 星爆星 …

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.

2024年10月27日 · We characterize luminosity components of Ultra/Luminous Infrared Galaxies (U/LIRGs) in multi-wavelength from the X-ray to far-infrared. A set of 63 AGN U/LIRGs was selected where these galaxies are...

The Great Observatories All-sky LIRG Survey (GOALS) was selected as a Spitzer cycle 3 Legacy Science program. It combines imaging and spectroscopic data from NASA's Spitzer, Hubble, Chandra and GALEX space-borne observatories in a comprehensive study of the most luminous infrared-selected galaxies in the local Universe.

2017年3月29日 · The Great Observatories All-Sky LIRG Survey (GOALS, Armus et al. 2009) combines both imaging and spectroscopic data for the complete sample of 201 Luminous Infrared Galaxies (LIRGs: log ) selected from the IRAS Revised Bright …

The Great Observatories All-sky LIRG Survey (GOALS) combines data from NASA’s Spitzer, Hubble, Chandra and GALEX observatories in a comprehensive imaging and spectroscopic survey of over 200 low redshift (z < 0.088), Luminous Infrared Galaxies (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 …

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.
