AGN feedback and quenching of star formation: a multiwavelength approach

We present a project that will carry out a multi- wavelength analysis of a large sample of galaxies se- lected from the SDSS DR2, to address AGN feedback in massive galaxies. We aim at quantifying (1) how com- mon are bulgeless galaxies harbouring AGN, (2) what is the degree of star formation and intrinsic extinction, (3) how massive are the central black holes and galaxy halos. This work will hopefully establish statistically significa nt and robust correlations. The nature of this study is fully adapted to benefit from the unique capabilities offered by the Virtual Observatory and was selected to be supported by the EURO-VO AIDA Research Initiative Call of 2008.
