J/MNRAS/390/881 Photometric characterization of the CIG sample (Durbala+, 2008) ================================================================================ Photometric characterization of a well-defined sample of isolated galaxies in the context of the AMIGA project. Durbala A., Sulentic J.W., Buta R., Verdes-montenegro L. =2008MNRAS.390..881D (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Galaxies, photometry ; Morphology ; Colors Keywords: galaxies: bulges, galaxies: evolution galaxies: fundamental parameters, galaxies: general galaxies: photometry, galaxies: structure Abstract: We perform a detailed photometric analysis (bulge-disc-bar decomposition and Concentration-Asymmetry-Clumpiness - CAS parametrization) for a well-defined sample of isolated galaxies, extracted from the Catalog of Isolated Galaxies and reevaluated morphologically in the context of the Analysis of the interstellar Medium of Isolated GAlaxies project. We focus on Sb-Sc morphological types, as they are the most representative population among the isolated spiral galaxies. Our analysis yields a large number of important galactic parameters and various correlation plots are used to seek relationships that might shed light on the processes involved in determining those parameters. Assuming that the bulge Sersic index and/or bulge/total luminosity ratios are reasonable diagnostics for pseudo- versus classical bulges, we conclude that the majority of late-type isolated disc galaxies likely host pseudo-bulges rather than classical bulges.
