The flattening and the orbital structure of early-type galaxies and collisionless N-body binary disk mergers
J. Thomas, R. Jesseit, R. P. Saglia +8
We use oblate axisymmetric dynamical models including dark halos to determine the orbital structure of intermediate mass to massive Coma early-type galaxies. We find a large variet…
The High-Mass End of the Black Hole Mass Function: Mass Estimates in Brightest Cluster Galaxies
E. Dalla Bonta', L. Ferrarese, E. M. Corsini +5
We present Hubble Space Telescope imaging and spectroscopic observations of three Brightest Cluster Galaxies, Abell 1836-BCG, Abell 2052-BCG, and Abell 3565-BCG, obtained with the…
Upper Limits on the Masses of 105 Supermassive Black Holes from Hubble Space Telescope/Space Telescope Imaging Spectrograph Archival Data
A. Beifiori, M. Sarzi, E. M. Corsini +4
Based on the modeling of the central emission-line width measured over sub-arcsecond apertures with the Hubble Space Telescope, we present stringent upper bounds on the mass of the…
Early-type galaxies in the near-infrared: 1.5-2.4\mum spectroscopy
M. Cesetti, V. D. Ivanov, L. Morelli +6
Near-infrared (hereafter NIR) data may provide complementary information to the traditional optical population synthesis analysis of unresolved stellar populations because the spec…
Stellar Populations of Bulges in 14 Cluster Disc Galaxies
L. Morelli, E. Pompei, A. Pizzella +6
Photometry and long-slit spectroscopy are presented for 14 S0 and spiral galaxies of the Fornax, Eridanus and Pegasus cluster, and NGC 7582 group. The structural parameters of the…
Confirmation of a Kinematic Diagnostic for Face-On B/P Bulges
J. Mendez-Abreu, E. M. Corsini, Victor P. Debattista +4
We present the results of high resolution absorption-line spectroscopy of 3 face-on galaxies, NGC 98, NGC 600, and NGC 1703 with the aim of searching for box/peanut (B/P)-shaped bu…
