13 Aug 2004 | | Journal: | Bull.Spec.Astrophys.Obs.N.Caucasus 57 (2004) 5-163 | | Subject: | astro-ph | | Abstract: | An all-sky catalog of 18020 disc-like galaxies is presented. The galaxies are selected from the Extended Source Catalog of the Two Micron All-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, K_s bands, its axial ratio, positional angle, index of luminosity concentration, as well as identification of the galaxy with the LEDA and the NED databases. Unlike the available optical catalogs, the new 2MFGC catalog seems to be more suitable to study cosmic streaming on a scale of z <= 0.1. The dipole moment of distribution of the bright (K < 11 mag) 2MFGC objects (l = 227 degr, b = 41 degr or SGL = 90 degr, SGB = -43 degr) lies within statistical errors (+/- 15 degr) in the direction of the IRAS dipole and the optical RFGC dipole. | | Source: | arXiv, astro-ph/0408257 | | Services: | Forum | Review | PDF | Favorites | |
