摘要：
We have observed a sample of 19 Very Luminous Infrared Galaxies (VLIRGs, L-IR[8-1000 mu m] 10(11) < L circle dot < 10(12)) with the Nordic Optical Telescope (NOT) + Andalusia Faint Object Spectrograph and Camera (ALFOSC) on La Palma, in B and I-bands. We discuss here the results of measuring preliminary morphological Concentration, Asymmetry, and Clumpiness (CAS) parameters for these galaxies. The results show VLIRGs as having similar Concentration to ULIRGs, but the Asymmetry and Clumpiness values show a considerably wider dispersion, which is unexpected. We are reanalyzing these preliminary results to assess their reliability.
