Ultraluminous Infrared Galaxies [PDF]
, 2006 Ever since their discovery in the 1970's, UltraLuminous InfraRed Galaxies (ULIRGs; classically Lir>10^12Lsun) have fascinated astronomers with their immense luminosities, and frustrated them due to their singularly opaque nature, almost in equal measure.

Mid infrared polarisation of Ultraluminous Infrared Galaxies [PDF]
Astronomy & 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.

ISO Spectroscopy of Ultraluminous Infrared Galaxies
Astrophysics and Space Science, 1999 Spectroscopy from the Infrared Space Observatory ISO has for the first timeprovided the sensitivity to exploit the diagnostic power ofmid-infrared fine structure lines and PAH features for the study ofultraluminous infrared galaxies (LIR >1012 L ⊙). We report on observations obtainedwith SWS, ISOPHOT-S, and the CVF option of ISOCAM.

The submillimetre properties of ultraluminous infrared galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 We present the results of SCUBA observations of a complete sample of local ULIRGs. Twenty of the initial sample of 23 sources are detected at 850 um and nearly half of the objects are also detected at 450 um. This data is combined with existing observations of a further seven ULIRGs to produce the largest sample of submm observations of ULIRGs ...

Ultraluminous Infrared Galaxies: Mergers of Sub‐L* Galaxies? [PDF]
The Astrophysical Journal, 2001 A sample of 27 low-redshift, mostly cool, ultraluminous infrared galaxies (ULIRGs) has been imaged at 1.6 μm with the Hubble Space Telescope (HST) Near-Infrared Camera and Multi-Object Spectrometer (NICMOS). The majority (67%) of the sample's galaxies are multiple-nucleus galaxies with projected separations of up to 17 kpc, and the rest of the sample ...

The near-infrared morphology of ultraluminous infrared galaxies [PDF]
The Astrophysical Journal, 1990 Near-infrared images at 1.25, 1.65, and 2.2 microns have been obtained of nine galaxies from the IRAS Bright Galaxy Sample with infrared luminosities greater than 10 to the 12th solar luminosities. Two of the 2.2-micron images reveal previously undetected double nuclei, increasing the number of close double nuclei known for this samples from two to ...
