Submillimeter Imaging of the Luminous Infrared Galaxy Pair VV 114
We report on 450 and 850 km observations of the interacting galaxy pair VV 114 E]W (IC 1623), taken with the SCUBA camera on the James Clerk Maxwell Telescope, and near-infrared observations taken with the UKIRT Fast-Track Imager on the UK Infrared Telescope. The system VV 114 is in an early stage of a gas-rich merger. We detect submillimeter emission extended over 30A (12 kpc) and Ðnd a good c...
متن کاملYet another galaxy identification for an ultraluminous X - ray source ⋆
We report on the identification of the optical and infrared counterparts of the ultraluminous X-ray source (ULX) XMMU J121214.5+131248 (NGC4168-ULX1). The optical spectrum yields a redshift of z = 0.217, which implies that the ULX is not associated with the nearby galaxy NGC 4168, but rather with a background object. Optical spectral line ratios and the spectral energy distribution constructed ...
متن کاملA submillimetre-selected, ultraluminous, active galaxy
We present a detailed study of SMM02399−0136, an ultraluminous, active galaxy selected from a sub-mm survey of the distant Universe. This object is the brightest source in the fields of four rich, lensing clusters, with a total area of ∼20 arcmin, that we have mapped with a sensitivity better than 2mJy beam at 850μm. We identify a compact optical counterpart with an apparent magnitude of B ∼ 23...
متن کاملExtended mid-infrared emission from VV 114: probing the birth of a ULIRG
We present our 5–16 μm spectro-imaging observations of VV114, an infrared luminous early-stage merger of two galaxies VV114E and VV114W, taken with the ISOCAM camera on-board the Infrared Space Observatory. We find that only 40% of the mid-infrared (MIR) flux is associated with a compact nuclear region of VV114E, while the rest of the emission originates from a rather diffuse component extended...
متن کاملThe Evolution of the Ultraluminous Infrared Galaxy Population from Redshift
We use redshift observations of two deep 1.4 GHz fields to probe the evolution of the bright end of the radio galaxy luminosity function to z = 1.5. We show that the number of galaxies with radio power that would correspond locally to an ultraluminous infrared galaxy (ULIG) evolves rapidly over this redshift range. The optical spectra and X-ray luminosities are used to refine this result by sep...
