Abstract:
This paper presents the results of spectral observations for the
largest complete sample of very luminous IRAS galaxies obtained to
date. The sample consists of those 73 objects for which
log(LIR/Lsun)>=11.5 (H0=50 km/s/Mpc, q0=0.5) and mag<=15.5, and
was extracted from the 2Jy IRAS redshift catalog (Cat. II/174). All
spectra were obtained using 2.16m telescope of Beijing Astronomical
Observatory during the years 1994-1996. A total of 123 galaxy spectra
were obtained with spectral ranges of 4400A to 7100A and 3500A to
8100A at resolutions of 11.2A and 9.3A respectively. In addition to
the 73 spectra for sample galaxies, we also present spectra for ten
non-sample galaxies and a further 40 for the companions of sample
galaxies. The data presented include nuclear spectrum and the
parameters describing the emission lines, absorption lines and
continua as well as DSS images and environmental parameters.
