| 内容記述 | Measurements of 158-micron forbidden emission taken from a sample of 13 gas-rich galaxies are analyzed. The new data are combined with the previous sample of six infrared-bright galaxies. The 158-micron line emission line is bright in all of the galaxies detected, amounting to between 0.1 and 0.2 percent of the total nuclear far-infrared luminosity, and is therefore one of the primary gas coolants in these regions. A close association between 158-micron line emission and CO line emission is noted, with the integrated 158-micron/CO line intensity ratio being substantially less in galaxies than in Galactic star-formation regions. However, for the starburst galaxies the integrated line intensity ratio is the same as that for star-formation regions in the Galaxy. |
