Far-Infrared Line Deficits in Ultraluminous Infrared Galaxies

Far-Infrared Line Deficits in Ultraluminous Infrared Galaxies
SPICA Science Conference from Exoplanets to Distant Galaxies: SPICA's New Window on the Cool Universe (June 18-21, 2013. Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, Japan We study the origin of the [O I] 63, [N II] 122, [O I] 145, and [C II] 158 line deficits in z less than 0.3 Ultraluminous Infrared Galaxies, using data from Herschel.

Mid infrared polarisation of Ultraluminous Infrared Galaxies [PDF]

Astronomy and Astrophysics, 2001
The mid infrared polarisation properties of four Ultraluminous Infrared Galaxies (ULIRGs) have been investigated by broad band filter observations with the ISOCAM instrument on board the Infrared Space Observatory (ISO). The wavelength region from 5 to 18 mic. was selected where the emission from the putative torus peaks.

Southern ultraluminous infrared galaxies: An optical and infrared database [PDF]

Astronomy and Astrophysics, 1997
We have carried out an optical and infrared study of 24 ultraluminous infrared galaxies in the southern hemisphere (SULIRGs). This flux limited, complete sample, has been extracted from the redshift survey of IRAS galaxies compiled by Strauss et al. (1992).

Ultraluminous infrared galaxies and the origin of quasars [PDF]

Astrophysical Journal, 1988
The Infrared Astronomical Satellite (IRAS) has discovered a class of ultraluminous infrared galaxies (L ir > 1012 L ⊙) that are bolometrically as luminous, and slightly more numerous than optically selected quasars in the local universe (z ≲ 0.2).

Hot Dust in Ultraluminous Infrared Galaxies

Astrophysics, 2017
Ultraluminous infrared galaxies with total luminosities an order of magnitude greater than that of our galaxy over wavelengths of λλ = 10-800 μm are characterized by a high mass concentration of dust. Because of this, the optical thickness of the interstellar gas is extremely high, especially in the central regions of the galaxies, ranging from 1 at ...
