| dc.description | We investigate the relation between the central velocity dispersion, sigma_0, and the circular velocity, V_c, in galaxies. In addition to previously available data, we consider an observationally homogeneus sample of 52 high surface brightness and 11 low surface brightness spiral galaxies. We performed a straight line regression analysis in a linear scale, finding a good fit, also for low sigma_0 galaxies, always rejected in the previous studies. Low surface brightness galaxies seem to behave differently, showing either higher values of V_c or lower values of sigma_0 with respect to their high surface brightness counterparts. | |
