Yu., Registration Date 10-02-2011 Organization Main Astronomical Observatory popup.description2 We have done the search of the isolated galaxies based on automatic selection of objects with infrared 2MASS survey and further visual inspection of their surroundings. Using the modified isolation criterion we created a new all sky catalog of isolated galaxies 2MIG. The catalog includes 3227 galaxies which are about 6% of 51572 galaxies of considered 2MASS XSC. The catalog 2MIG includes galaxies with magnitudes K <12.0 mag and diameters a> 30''. The effective depth of the catalog is 6700 km / s. The catalog of the 520 most isolated all sky nearby galaxies with velocities less than 3500 km / s was also created. This population of "cosmic orphans" - Local Orphan Galaxies (= LOG) consists 4.8% among the 10900 galaxies with the specified velocities. The distribution of galaxies on the sky looks quite uniform: they avoid the regions of nearby clusters and groups as well as known voids. Half of the sample are the galaxies of morphological types Sdm, Im, Ir, having no bulge. For the LOG galaxies the optical and radio properties were calculated. Note that the median value of the mass ratio "gas/stars" in LOG galaxies is above 1. Product Description popup.authors Вавилова І.Б. Елиїв Андрій Андрійович Караченцева В.Ю. Кудря Ю. М. Мельник О.В.
