The V_c-sigma_0 relation in Low Surface Brightness galaxies: including the light concentration
Abstract
It has been found that there is a strong correlation between the circular velocity V_c and the central stellar velocity dispersion \sigma_0 of galaxies. In this respect, low surface brightness galaxies (LSB) follow a different relation when compared to Elliptical and high surface brightness (HSB) galaxies. The intrinsic scatter of the V_c-\sigma_0 is partially due to the different concentration of the light distribution. In this work we measure the C_28 concentration parameter for a sample of 17 LSB finding that the C_28 parameter does not account for the different behavior in the for this class of objects.
