Dark matter in early-type spiral galaxies: the case of NGC 2179 and of NGC 2775
Corsini, E.M.; Pizzella, A.; Sarzi, M.; Cinzano, P.; Vega Beltran, J.; Funes, J.; Bertola, F.; Persic, M.; Salucci, P. (1999)We present the stellar and ionized-gas velocity curves and velocity-dispersion profiles along the major axis for six early-type spiral galaxies. Two of these galaxies, namely NGC 2179 and NGC 2775, are particularly suited ... -
The High-Mass End of the Black Hole Mass Function: Mass Estimates in Brightest Cluster Galaxies
Dalla Bonta, E.; Ferrarese, L.; Corsini, E.M.; Miralda-Escude, J.; Coccato, L.; Sarzi, M.; Pizzella, A.; Beifiori, A. (2009) -
Multiband photometric decomposition of nuclear stellar disks
Morelli, L.; Cesetti, M.; Corsini, E.M.; Pizzella, A.; Dalla Bonta, E.; Sarzi, M.; Bertola, F. (2010)Context. Small, bright stellar disks with scale lengths of a few tens of parsec are known to reside in the center of galaxies. They are believed to have formed in a dissipational process as the end result of star formation ... -
NGC 4435: a bulge-dominated galaxy with an unforeseen low-mass central black hole
Coccato, L.; Sarzi, M.; Pizzella, A.; Corsini, E.M.; Dalla Bonta, E.; Bertola, F. (2006) -
NGC 4672: A new case of an early-type disk galaxy with an orthogonally decoupled core
Sarzi, M.; Corsini, E.M.; Pizzella, A.; Beltran, V.; Cappellari, M.; Funes, J.; Bertola, F. (2000)We report the case of the early-type disk galaxy NGC 4672 as a new example of a galaxy characterized by the orthogonal geometrical decoupling between bulge and disk. The morphological features of this galaxy are discussed ... -
Nuclear discs as clocks for the assembly history of early-type galaxies: the case of NGC 4458
Sarzi, M.; Ledo, H.~R.; Coccato, L.; Corsini, E.~M.; Dotti, M.; Khochfar, S.; Maraston, C.; Morelli, L.; Pizzella, A. (2016-04-01)Approximately 20 per cent of early-type galaxies host small nuclear stellar discs that are tens to a few hundred parsecs in size. Such discs are expected to be easily disrupted during major galactic encounters, hence their ... -
Stellar Populations of Bulges in 14 Cluster Disc Galaxies
Morelli, L.; Pompei, E.; Pizzella, A.; Mendez-Abreu, J.; Corsini, E.M.; Coccato, L.; Saglia, R.P.; Sarzi, M.; Bertola, F. (2008) -
Structure and dynamics of galaxies with a low surface brightness disc. I. The stellar and ionised-gas kinematics
Pizzella, A.; Corsini, E.M.; Sarzi, M.; Magorrian, J.; Mendez-Abreu, J.; Coccato, L.; Morelli, L.; Bertola, F. (2008) -
Upper limits on the masses of 105 supermassive black holes from Hubble Space Telescope / space telescope imaging spectrograph archival data
Beifiori, A.; Sarzi, M.; Corsini, E.M.; Bonta, E.D.; Pizzella, A.; Coccato, L.; Bertola, F. (2009)Based on the modeling of the central emission-line width measured over subarcsecond apertures with the Hubble Space Telescope, we present stringent upper bounds on the mass of the central supermassive black hole, M •, for ...
