We have compiled a catalogue of the gas content for a sample of 1916 galaxies, considered to be a fair representation of normality. The definition of a normal galaxy adopted in this work implies that we have purposely excluded from the catalogue galaxies having distorted morphology (such as interaction bridges, tails or lopsidedness) and/or any signature of peculiar kinematics (such as polar rings, counterrotating disks or other decoupled components). In contrast, we have included systems hosting active galactic nuclei (AGN) in the catalogue. This catalogue revises previous compendia on the ISM content of galaxies published by Bregman et al. (1992ApJ...387..484B) and Casoli et al. (1998A&A...331..451C), and compiles data available in the literature from several small samples of galaxies. Masses for warm dust, atomic and molecular gas, as well as X-ray luminosities have been converted to a uniform distance scale taken from the Catalogue of Principal Galaxies (PGC). We have used two different normalization factors to explore the variation of the gas content along the Hubble sequence: the blue luminosity (LB) and the square of linear diameter (D_25_^2^). Our catalogue significantly improves the statistics of previous reference catalogues and can be used in future studies to define a template ISM content for normal galaxies along the Hubble sequence.
The catalog of isolated galaxies is defined on the basis of the Palomar Sky Survey. It contains 1051 isolated galaxies with apparent magnitudes brighter than 15.7 and north of declination -3{deg}. Compared to the original version published in 1973 (Comm. Special Astrophys. Obs. of USSR, No. 8), new data about the morphological types, the isolation class, and the radial velocities have been added. The catalog includes running numbers for the galaxies, equatorial coordinates, isolation classes, apparent magnitudes, morphological types, major axes, axial ratios, and radial velocities.
Markarian galaxies have a moderate to strong ultraviolet continuum as detected by an objective-prism survey at Byurakan Observatory from 1965 to 1978. The survey was done with a 40-inch Schmidt telescope with a dispersion of 2500 angstroms/millimeter at H-alpha. The catalog contains no galaxies brighter than mag 13.0 or fainter than mag 17.5. The catalog fields are Markarian Identification number; S(eyfert) or Q(uasar) flag; cross identifications to other catalogs; B1950 positions; major and minor axis (arcsec); magnitude and spectral types, including a code for the strength of the UV continuum. This catalogue is superseded by the First Byurakan Survey (see the "See Also" section below) The original documentation was by Robert S. Hill and Lee E. Brotzman in the "adc.doc" file (From the CD-ROM "Selected Astronomical Catalogs" Vol. 1 (1992), directory "nonstell/galaxies/mkn")
This "catalog of principal galaxies" constitutes the basis of the "Third Reference Catalogue of Bright Galaxies" (RC3). It lists equatorial coordinates for the equinoxes 1950 and 2000 and cross identifications for 73197 galaxies. Of the 73197 galaxies, 40932 have coordinates with standard deviations of less than ten arcsec. Listed are 131,601 names from the 38 most common sources. These data are given when available: morphological descriptions, apparent major and minor axes, apparent magnitudes, radial velocities, and position angles.

Description:
This "Catalogue of Southern Peculiar Galaxies and Associations" is a complete and detailed catalogue of all the most interesting galaxies and most striking apparent associations of galaxies in the Southern sky. The printed catalogue is made of two volumes: Volume I which lists the Peculiar Galaxies, and Volume II which contains photographs of galaxies which are representative of the various Categories used in the Classification scheme presented in Volume I.
We present an extension of our previous research on the early-type galaxy population of the Antlia cluster (d~35Mpc), achieving a total coverage of ~2.6deg^2^ and performing surface photometry for ~300 galaxies, 130 of which are new uncatalogued ones. Such new galaxies mainly fall in the low surface brightness (LSB) regime, but there are also some lenticulars (S0) which support the existence of unique functions that connect bright and dwarf galaxies in the scaling relations. We analyse the projected spatial distribution of galaxies up to a distance of ~800kpc from NGC 3268, the adopted centre, as well as the radial velocity distribution and the correlation between galaxy colour and effective radius with the projected spatial distribution. We also obtain the luminosity function of the early-type galaxies and the distribution of stellar masses using the T1-band magnitudes and adopted mass-luminosity ratios. Additionally, we correlate the central galaxy distribution with an X-ray emission map from the literature. Based on the analysis of the radial velocities and galaxy colour distributions, we find that galaxies redder than the colour-magnitude relation (CMR) have a velocity distribution strongly concentrated towards the values of the dominant galaxies and are homogeneously distributed throughout the cluster. Those bluer than the CMR, in turn, have a much more extended radial velocity distribution and are concentrated towards the centre of the cluster. We also identify 12 candidates to ultra diffuse galaxies (UDG), that seem to be split into two families, and speculate about their origins in the context of the cluster structure.
This catalog contains for 10411 objects, the Abell, Zwicky, and Kalinkov numbers of groups of galaxies. In addition, it contains: Abell or Zwicky coordinates, the Abell or Zwicky numbers of the supercluster which contains each group, the diameter (Zwicky), the magnitude (Abell), the compactness (Zwicky), the distance of the group (both Abell and Zwicky), the richness (Abell) and the population (Zwicky).
We present astrometric results for compact extragalactic objects observed with the Very Long Baseline Array at radio frequencies of 24 and 43GHz. Data were obtained from ten 24-hr observing sessions made over a five-year period. These observations were motivated by the need to extend the International Celestial Reference Frame (ICRF) to higher radio frequencies to enable improved deep space navigation after 2016 and to improve state-of-the-art astrometry. Source coordinates for 268 sources were estimated at 24GHz and for 131 sources at 43GHz.
We have measured the submilliarcsecond structure of 274 extragalactic sources at 24 and 43 GHz in order to assess their astrometric suitability for use in a high-frequency celestial reference frame (CRF). Ten sessions of observations with the Very Long Baseline Array have been conducted over the course of ~5 years, with a total of 1339 images produced for the 274 sources. There are several quantities that can be used to characterize the impact of intrinsic source structure on astrometric observations including the source flux density, the flux density variability, the source structure index, the source compactness, and the compactness variability.
