A radio spectral line study of the 2 Jy IRAS-NVSS sample. I.


Abstract (from CDS):

We present results from an ongoing survey for the H I 21 cm line and the OH 18 cm lines in infrared galaxies with the Arecibo 305 m Radio Telescope. The observations of 85 galaxies extracted from the 2 Jy IRAS-NVSS sample in the right ascension (B1950) range 20h-00h are reported in this paper. We detected the H I 21 cm line in 82 of these galaxies, with 18 being new detections, and the OH 18 cm lines in seven galaxies, with four being new detections. In some cases, the H I spectra show the classic double-horned or single-peaked emission profiles. However, the majority exhibit distorted H I spectral features indicating that the galaxies are in interacting and/or merging systems. From these H I and OH observations, various properties of the sample are derived and reported.
