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.
