J/MNRAS/414/702     Optical classification of southern ULIRGs      (Lee+, 2011)

Optical spectral classification of southern ultraluminous infrared galaxies. Lee J.C., Hwang H.S., Lee M.G., Kim M., Kim S.C. <Mon. Not. R. Astron. Soc., 414, 702-712 (2011)> =2011MNRAS.414..702L
ADC_Keywords: Galaxies, IR ; Spectroscopy ; Spectral types Keywords: galaxies: active - galaxies: general - galaxies: starburst - infrared: galaxies Abstract: We present a study of the optical spectral properties of 115 ultraluminous infrared galaxies (ULIRGs) in the southern sky. Using the optical spectra obtained at the Cerro Tololo Inter-American Observatory (CTIO) 4m telescope and provided by the Two-degree Field (2dF) Galaxy Redshift Survey and the Six-degree Field (6dF) Galaxy Survey, we measure emission linewidths and fluxes for spectral classification. Description: The optical spectra of the 2dFGRS galaxies were taken with the 2dF multi-object spectrograph on the Anglo-Australian Telescope. File Summary:

Global notes: Note (G1): Linewidths below 100km/s are not shown. Note (G2): The ratios are corrected for Galactic extinction and stellar absorption. The internal extinction correction is applied, if available. Note (G3): Line flux qualities are expressed as one digit (0 to 4) for each line: Hβ, [OIII]λ5007, [OI]λ6300, Hα, [NII]λ6584, [SII]λ6717 and [SII]λ6731. Each digit represents a quality as: 0 = unmeasurable 1 = low 2 = moderate 3 = High
