|The Arizona-New Mexico Spectroscopic Survey of Galaxies. III. On Galaxy Populations|
We examine the population statistics for two samples of galaxies in thedirection of the Perseus supercluster. One sample, with N=258 galaxieshaving MB<=-19.52+5log(h) and vh<=8000 kms-1, is complete for those galaxies within the boundaries ofour survey region that have apparent magnitudes mp<=15.0in the Zwicky catalog. A more restrictive sample with N=177 galaxieshaving MB<=-20.00+5log(h) (with the same redshift range)is complete in both luminosity and volume. We derive the statistics forthe relative incidence of galaxies in the following spectroscopicclasses: (1) absorption line only, (2) collisionally-excited emissionlines only, (3) nuclear H II region, (4) starburst, (5) LINER, and (6)Seyfert 1.8-2.
|The Arizona-New Mexico Spectroscopic Survey of Galaxies. I. Data for the Western End of the Perseus Supercluster|
We present new optical spectroscopic data for 347 galaxies in the regionof the Perseus supercluster. The new data were obtained using theSteward Observatory 2.3 m telescope and cover the whole optical window.Included are redshifts (for 345 objects), absorption-line equivalentwidths, a continuum index measuring the 4000 Å break, andemission-line flux ratios. After 11 objects are rejected for being toofaint and redshifts for 26 objects are added from the literature, wearrive at a complete sample of 361 galaxies. The distribution ofredshifts for the whole sample is examined, and we show the relationshipof the continuum index to morphology.
|Peculiar velocities of clusters in the Perseus-Pisces supercluster|
Photometry is presented for spiral galaxies in five clusters of galaxiesin the direction of the Perseus-Pisces supercluster. The 21 cmobservations of these galaxies by Giovanelli et al. (1982, 1986) areemployed to measure distances of these clusters by means of theTully-Fisher relation. Most of these are in fact more distant than thesupercluster and have peculiar velocities averaging 400 km/s. This isbroadly in agreement with the earlier result of Willick (1990, 1991) whoanalyzed a large field sample. A local model in which galaxies areinfalling to two mass concentrations, one in Perseus-Pisces and one inHydra-Centaurus, fits the data at least as well as bulk flow. Thepresent data leave both these possibilities open.
|A 21 CM survey of the Pisces-Perseus supercluster. IV - Addenda to the declination zone 21.5 deg to 33.5 deg|
Using the 305-m Arecibo telescope, 21-cm line data on 472 disk galaxiesin the Pisces-Perseus supercluster have been obtained. Data on galaxiessmaller than 1 arcmin are presented for the declination strips coveredin previous studies (Giovanelli and Haynes, 1985 and Giovanelli et al.,1986). Tables of the 21-cm line data for this region are presented.
|KISO survey for ultraviolet-excess galaxies. V.|
Presented here are the fifth list and identification charts of theultraviolet-excess galaxies which have been detected on the multi-colorplates taken with the Kiso Schmidt telescope for 10 survey fields. Inthe sky area of some 300 square degrees 628 objects are catalogued downto the photographic magnitude of about 17.5.
