A compendium of far-infrared line and continuum emission for 227 galaxies observed by the infrared space observatory.


Abstract (from CDS):

Far-infrared line and continuum fluxes are presented for a sample of 227 galaxies observed with the Long Wavelength Spectrometer on the Infrared Space Observatory. The galaxy sample includes normal star-forming systems, starbursts, and active galactic nuclei covering a wide range of colors and morphologies. The data set spans some 1300 line fluxes, 600 line upper limits, and 800 continuum fluxes. Several fine-structure emission lines are detected that arise in either photodissociation or H II regions: [O III] 52 µm, [N III] 57 µm, [O I] 63 µm, [O III] 88 µm, [N II] 122 µm, [O I] 145 µm, and [C II] 158 µm. Molecular lines such as OH at 53, 79, 84, 119, and 163 µm, and H2 O at 58, 66, 75, 101, and 108 µm are also detected in some galaxies. In addition to those lines emitted by the target galaxies, serendipitous detections of Milky Way [C II] 158 µm and an unidentified line near 74 µm in NGC 1068 are also reported. Finally, continuum fluxes at 52, 57, 63, 88, 122, 145, 158, and 170 µm are derived for a subset of galaxies in which the far-infrared emission is contained within the ∼75" ISO LWS beam. The statistics of this large database of continuum and line fluxes, including trends in line ratios with the far-infrared color and infrared-to-optical ratio, are explored.
