Morphology and evolution of VIPERS galaxies

Janusz Krywult, Agnieszka Pollo and The VIPERS Team

Using the spectroscopic and photometric data from the VIMOS Public Extragalactic Redshift Survey (VIPERS), together with the CFHTLS T0006 CCD images, we analyze co-evolution of rest-frame colours and Sérsic indices of the early and late-type galaxies in the redshift range 0.5 < z < 1.0. We find a strong Gaussian bimodality of both the galaxy rest-frame colour and Sérsic index distribution in the redshift - luminosity plane. We propose a new empirical model of galaxy colour and Sérsic index dependence on redshift and luminosity, to study the dynamical and chemical evolution of galaxies.
