Far-Infrared Line Deficits in Ultraluminous Infrared Galaxies
Far-Infrared Line Deficits in Ultraluminous Infrared GalaxiesSPICA 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.

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).

Follow-up near-infrared spectroscopy of ultraluminous infrared galaxies observed by ISO
Astronomy and Astrophysics, 2005 We present low resolution near-infrared spectroscopy of an unbiased sample of 24 ultraluminous infrared galaxies (ULIRGs), selected from samples previously observed spectroscopically in the mid-infrared with the Infrared Space Observatory (ISO ...

Hot Dust in Ultraluminous Infrared Galaxies
Astrophysics, 2017Ultraluminous 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 ...

Ejection from Ultraluminous Infrared Galaxies
2000Active galaxies, particularly Seyferts, have been shown to eject material in various forms including quasars with high intrinsic redshifts. A class of active galaxy which has so far not been analyzed from this standpoint is the so called Ultra Luminous Infrared Galaxies (ULRIG’s).

Extinction law in ultraluminous infrared galaxies at z∼ 1 [PDF]
Monthly Notices of the Royal Astronomical Society, 2011 We analyse the multiwavelength photometric and spectroscopic data of 12 ultraluminous infrared galaxies (ULIRGs) at z∼1 and compare them with models of stars and dust in order to study the extinction law and star formation in young infrared (IR) galaxies.

Near-Infrared Spectroscopy of Ultraluminous Infrared Galaxies
1994We report K band spectra of fourteen ultraluminous (LIR ≥ 1012L⊙) galaxies from the IRAS Extended Bright Galaxy Sample (EBGS) and ten less luminous EBGS galaxies. For the lower luminosity systems, good correlations are found between the H2 v=1-0S(1) and far-infrared (FIR) fluxes, and Brγ and FIR fluxes.

Ultraluminous Infrared Galaxies: Far-Infrared Highlights
Astrophysics and Space Science, 1999We discuss two significant recent developments in the far-IRwith relevance to the study of Ultraluminous Infrared Galaxies(ULIRGs). The first of these is the discovery of an isotropiccosmological infrared background radiation (CIB). This has beendetected in observations by two different instruments (FIRAS (Puget etal. 1996, Hauser et al.

Molecular Gas in Ultraluminous Infrared Galaxies
1997The discovery of CO emission (Wilson, Jefferts & Penzias 1970) 25 years ago opened a major new astronomical window which has led to important advances in many areas of Galactic and extragalactic astronomy. The strength and ubiquity of the CO lines, CO isotopic lines, and other millimeter transitions have provided extraordinary diagnostics for studying ...
