  With the main goal of finding bulgeless galaxies harbouring super massive
black holes and showing, at most, just residual star formation activity, we
have selected a sample of massive bulgeless red sequence galaxies from the
SDSS-DR7, based on the NYU-VAGC catalogue. Multivavelength data were retrieved
using EURO-VO tools, and the objects are characterised in terms of degree of
star formation and the presence of an AGN. We have found seven objects that are
quenched massive galaxies, that have no prominent bulge and that show signs of
extra activity in their nuclei, five of them being central in their halo. These
objects are rather robust candidates for rare systems that, though devoid of a
significant bulge, harbor a supermassive black hole with an activity level
likely capable of having halted the star formation through feedback.
