The 2MASS-selected Flat Galaxy Catalog
An all-sky catalog of 18020 disc-like galaxies is presented. Thegalaxies are selected from the Extended Source Catalog of the Two MicronAll-Sky Survey (XSC 2MASS) basing on their 2MASS axial ratio a/b ≥ 3.The Catalog contains data on magnitudes of a galaxy in the J, H,KS bands, its axial ratio, positional angle, index ofluminosity concentration, as well as identification of the galaxy withthe LEDA and the NED databases. Unlike the available optical catalogs,the new 2MFGC catalog seems to be more suitable to study cosmicstreaming on a scale of z <~ 0.1. The dipole moment of distributionof the bright (K < 11m) 2MFGC objects (l = 227°, b =41° or SGL = 90°, SGB = -43°) lies within statistical errors(±15°) in the direction of the IRAS dipole and the opticalRFGC dipole.
| CAIRNS: The Cluster and Infall Region Nearby Survey. I. Redshifts and Mass Profiles
The CAIRNS (Cluster and Infall Region Nearby Survey) project is aspectroscopic survey of the infall regions surrounding eight nearby,rich, X-ray-luminous clusters of galaxies. We have collected 15,654redshifts (3471 new or remeasured) within ~5-10 h-1 Mpc ofthe centers of the clusters, making it the largest study of the infallregions of clusters. We determine cluster membership and the massprofiles of the clusters based on the phase-space distribution of thegalaxies. All of the clusters display decreasing velocity dispersionprofiles. The mass profiles are fitted well by functional forms based onnumerical simulations but exclude an isothermal sphere. Specifically,NFW and Hernquist models provide good descriptions of cluster massprofiles to their turnaround radii. Our sample shows that the predictedinfall pattern is ubiquitous in rich, X-ray-luminous clusters over alarge mass range. The caustic mass estimates are in excellent agreementwith independent X-ray estimates at small radii and with virialestimates at intermediate radii. The mean ratio of the caustic mass tothe X-ray mass is 1.03+/-0.11, and the mean ratio of the caustic mass tothe virial mass (when corrected for the surface pressure term) is0.93+/-0.07. We further demonstrate that the caustic technique providesreasonable mass estimates even in merging clusters.
| Arcsecond Positions of UGC Galaxies
We present accurate B1950 and J2000 positions for all confirmed galaxiesin the Uppsala General Catalog (UGC). The positions were measuredvisually from Digitized Sky Survey images with rms uncertaintiesσ<=[(1.2")2+(θ/100)2]1/2,where θ is the major-axis diameter. We compared each galaxymeasured with the original UGC description to ensure high reliability.The full position list is available in the electronic version only.
| Properties of nearby clusters of galaxies. III. A 76, A 157, A 407, A 505, A 671, A 779, A 1700, A 2028, A 2040, A 2052 A 2063, A 2065, A 2593, A 2657, A 2670
We present F band photometry, from digitized 48-inch Palomar plates, of2818 galaxies brighter than m_3+3 in 15 Abell clusters. For each galaxy,absolute coordinates, magnitude, size, ellipticity and orientation aregiven. For each cluster we provide finding charts and contour maps ofthe galaxy surface density. The absolute coordinates of the galaxies ofother 8 clusters presented in the first paper of this series are alsoincluded.
| An image database. II. Catalogue between δ=-30deg and δ=70deg.
A preliminary list of 68.040 galaxies was built from extraction of35.841 digitized images of the Palomar Sky Survey (Paper I). For eachgalaxy, the basic parameters are obtained: coordinates, diameter, axisratio, total magnitude, position angle. On this preliminary list, weapply severe selection rules to get a catalog of 28.000 galaxies, wellidentified and well documented. For each parameter, a comparison is madewith standard measurements. The accuracy of the raw photometricparameters is quite good despite of the simplicity of the method.Without any local correction, the standard error on the total magnitudeis about 0.5 magnitude up to a total magnitude of B_T_=17. Significantsecondary effects are detected concerning the magnitudes: distance toplate center effect and air-mass effect.
| Properties of nearby clusters of galaxies. I - A 195, A 465, A 1185, A 1213, A 1413, A 1775, A 2319 and A 2597
A study of the properties of nearby clusters of galaxies has beenundertaken. This paper describes the data, derived from automated scansof photographic plates. Different methods for the evaluation of clustercenter, ellipticity, and orientation are compared, and errors areestimated by Monte Carlo simulations. Results are presented of theanalysis of 1256 galaxies brighter than m3 + 3 in eight Abell clusters.It is found that different methods give consistent estimates ofellipticity and orientation, provided the radial dependence of thesequantities is taken into account. It is also found that centraldensities are consistent with isothermal fits if the center is selectedas the baricenter of the cluster. For each galaxy, rectangularcoordinates, magnitude, size, ellipticity, and orientation are given.Each cluster is provided with identification maps and contour maps ofgalaxy surface density.
| Forbidden O III emission in two magnitude-limited field-galaxy surveys
The paper presents emission-line strengths for 394 galaxies from thefield-galaxy redshift surveys of Kirshner, Oemler, and Schechter (1978)and Kirshner et al. (1983) as part of a study of the nature of field andvoid galaxies. These data are 95 percent complete in their coverage ofthe forbidden O III 5007, 4959 A emission lines. It is found that 8.8 +or - 1.5 percent of a J magnitude-limited data set have forbidden O III5007 A emission equivalent widths greater than 10 A. There is noevidence that the spatial distribution of emission-line galaxies in eachfield differs from that of galaxies without emission. However, there isa significant increase in the fraction of galaxies with strong forbiddenO III emission in the southern fields of the Kirshner, Oemler, andSchechter (1978) survey as compared with the other survey fields. Theresults are consistent with the conclusion that the fraction of galaxieswith emission is larger in the Bootes void than in the general field,but tighter constraints on the void normal galaxy population are neededto improve the statistics.
| The optical luminosity function of a 60-micron flux-limited sample of IRAS galaxies
A determination is made of the optical luminosity function (OPLF) of aninfrared flux-limited sample of IRAS galaxies. The sample includes 92objects; among these are an infrared-loud quasar and two previouslyknown Seyferts. The OPLF of the IRAS galaxies in the sample shows thatin the magnitude range between -22 and 18, IRAS galaxies represent about15 percent of field galaxies. At low luminosities, Mj greater than -19mag, there may be a deficiency of IRAS galaxies relative to the fieldgalaxies. The far-IR luminosity function of the sample is also derived;it agrees well with other determinations.
| A deep survey of galaxies
A sample of galaxies in six fields, each of area 2 sq deg, located inthe North and South galactic polar caps is presented. Photoelectricallycalibrated photographic magnitudes and J-F colors have been determinedfor 512 galaxies brighter than completeness limits which range from F =16.5 to F = 17.2 among the fields. Velocities, with typical accuraciesof 150 km/s, have been obtained for 280 of the brighter galaxies. Usingthese data and previously published work, we determine the generalgalaxy luminosity function parameters and the mean visual luminositydensity of the universe.
| A study of field galaxies. I - Redshifts and photometry of a complete sample of galaxies
As a first step towards a redetermination of the luminosity function andspace distribution of field galaxies, data are presented on amagnitude-limited sample of galaxies in eight fields in the north andsouth galactic polar caps. Redshifts, accurate to about 100 km/s havebeen obtained for 164 of 184 galaxies brighter than J=15.0 (Bapproximately equal to 15.5). Magnitudes and colors have also beenmeasured for a large sample of 807 galaxies, complete to J approximatelyequal to 15.7.
