VIPERS: Galaxy morphology at z ~ 1

Janusz Krywult, Agnieszka Pollo and The VIPERS Team

We use spectroscopic VIPERS data to analyze morphological properties of galaxies at z ~ 1. To determine galaxy morphologies, we estimate their Sersic index. Then, we correlate it with galaxy rest-frame colors, and other physical properties. We find that the distribution of Sérsic index of our sample is bimodal, and well correlated with the color-bimodality of the galaxy distribution. So-called green valley (i.e. intermediate colour) galaxies often have intermediate values of Sérsic index which may support the hypothesis that at least a part of this population are galaxies in the transition phase.
