LUMINOUS INFRARED GALAXIES

Annual Review of Astronomy and Astrophysics, 1996
▪ Abstract  At luminosities above 1011 [Formula: see text], infrared galaxies become the dominant population of extragalactic objects in the local Universe (z ≲ 0.3), being more numerous than optically selected starburst and Seyfert galaxies and quasi-stellar objects at comparable bolometric luminosity.

A tidal disruption event in the nearby ultra-luminous infrared galaxy F01004-2237

Nature Astronomy, 2017
Tidal disruption events (TDEs), in which stars are gravitationally disrupted as they pass close to the supermassive black holes in the centres of galaxies1, are potentially important probes of strong gravity and accretion physics.

CO in infrared luminous galaxies

2008
There has been considerable recent interest in the properties of infrared galaxies due to the discovery by the Infrared Astronomical Satellite (IRAS) of a class of luminous galaxies which emit the bulk of their energy in the far-infrared (Houck et al. 1984; Soifer et al. 1984).

The Environments of Luminous Infrared Galaxies

2011
This work studies the relationship between SFR, stellar mass and environment of local IR galaxies, especially LIRGs. It is found that the L { IR} ∼ 1011 L ⊙ marks an important luminosity point among IR galaxies - the large scale density of environment around LIRGs correlates strongly with their SFR above this value at a fixed stellar mass. On the other

ISO spectroscopy of luminous infrared galaxies

Advances in Space Research, 2000
Abstract Spectroscopy from the Infrared Space Observatory ISO has for the first time provided the sensitivity to observe mid-infrared fine structure lines and PAH features in a wide range of luminous infrared galaxies. We report on observations obtained with SWS, ISOPHOT-S, and the ISOCAM CVF and show that the mid-IR spectral features are excellent ...

SED DECOMPOSITION OF INFRARED-LUMINOUS GALAXIES [PDF]

open access: possiblePublications of The Korean Astronomical Society, 2012
We select infrared-luminous galaxies by cross-matching the SDSS spectroscopic sample of galaxies with the WISE all-sky survey catalog. Based on photometric data points covering from SDSS u-band to WISE , their spectral energy distributions (SEDs) are separated into AGN, elliptical, spiral, and irregular galaxy components.

The Nature of Ultra-Luminous Infrared Galaxies

2000
We review investigations with SWS, ISOPHOT-S, and ISOCAM-CVF of several samples of ultra-luminous infrared galaxies (ULIRGs) drawn from IRAS catalogs. The mid-IR data indicate that the majority of the local ULIRG population is predominantly powered by star formation but that AGN activity plays a signi.cant role in many sources and dominates the most ...
