Ultraluminous Infrared Galaxies
The IRAS survey of the local universe (z_0.1) has revealed the existence of a class of ultraluminous infrared galaxies with L(8-1000#m) > 1012L® that are slightly more numerous, and as luminous as optically selected quasars at similar redshift. Optical CCD images of these infrared galaxies show that nearly all are advanced mergers. Millimeter-wave CO (1 _ 0) observations indicate that these int...
متن کاملUltraluminous Infrared Galaxies
Ever since their discovery in the 1970’s, UltraLuminous InfraRed Galaxies (ULIRGs; classically Lir > 10 12L⊙) have fascinated astronomers with their immense luminosities, and frustrated them due to their singularly opaque nature, almost in equal measure. Over the last decade, however, comprehensive observations from the X-ray through to the radio have produced a consensus picture of local ULIRG...

This paper reviews the results from recent optical and nearinfrared spectroscopic studies of ultraluminous infrared galaxies.
متن کاملStis Ultraviolet/optical Spectroscopy of 'warm' Ultraluminous Infrared Galaxies
We present high spatial resolution ultraviolet and optical spectroscopy, obtained using the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope, of nuclear structures within four 'warm' Ultraluminous Infrared Galaxies (ULIRGs). We find an AGN in at least three, and probably all four of our sample, hosted in a compact, optically luminous 'knot'. In three cases these knots we...
متن کاملMid Infrared Polarisation of Ultraluminous Infrared Galaxies ⋆
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 18μm was selected where the emission from the putative torus peaks. We report detection of polarisation for all ULIRGs studied. The fractional p...
