3 Oct 2005 | | Subject: | astro-ph | | Abstract: | We present a new version of the list of peculiar velocities of 1561 flat edge-on spirals from the RFGC catalogue. It differs from the previous version by 233 new data and 34 corrected data. A new regression was used for distances estimation based on the Tully-Fisher relationship in the "linear diameter - HI line width" variant. Moreover, we present velocities for 3 models of galaxies collective motion. They are a D-model (dipole, Hubble expansion + bulk motion with constant speed), DQ-model (a quadrupole terms are added) and DQO-model (DQ-model + octopole). | | Source: | arXiv, astro-ph/0510037 | | Services: | Forum | Review | PDF | Favorites | |
