NGC 4435: a bulge dominated galaxy with an unforeseen low mass central   black hole
  We present the ionised gas kinematics of the SB0 galaxy NGC 4435 from spectra obtained with the Space Telescope Imaging Spectrograph. This galaxy has been selected on the basis of its ground-based spectroscopy, for displaying a position velocity diagram consistent with the presence of a circumnuclear Keplerian disc rotating around a supermassive black hole (SMBH). We obtained the Halpha and [NII](6583) kinematics kinematics in the galaxy nucleus along the major axis and two parallel offset positions. We built a dynamical model of the gaseous disc taking into account the whole bidimensional velocity field and the instrumental set-up. For the mass of the central SMBH we found an upper limit of 7.5e6 Msun at 3sigma level. This indicates that the mass of SMBH of NGC 4435 is lower than the one expected from the Mbh-sigma (5e7 Msun) and near-infrared Mbh- Lbulge (4e7 Msun) relationships.
