2011AstBu..66....1K Catalog of nearby isolated galaxies in the volume z < 0.01 Karachentsev, I. D.; Makarov, D. I.; Karachentseva, V. E.; Melnyk, O. V. Abstract. We present a catalog of 520 most isolated nearby galaxies with angular velocities V_ LG_ < 3500 km/s, covering the entire sky. This population of "space orphans" makes up 4.8% among 10 900 galaxies with measured radial velocities. We describe the isolation criterion used to select our sample, called the "Local Orphan Galaxies"(LOG), and discuss their basic optical and HI properties. A half of the LOG catalog is occupied by the Sdm, Im and Ir morphological type galaxies without a bulge. The median ratio M_gas_/ M_star_ in the LOG galaxies exceeds 1. The distribution of the catalog galaxies on the sky looks uniform with some signatures of a weak clustering on the scale of about 0.5 Mpc. The LOG galaxies are located in the regions where the mean local density of matter is approximately 50 times lower than the mean global density. We indicate a number of LOG galaxies with distorted structures, which may be the consequence of interaction of isolated galaxies with massive dark objects. Key words: astronomical databases, catalogs-galaxies, general-galaxies, evolution-galaxies, formation
