Kinematic properties of early-type galaxy haloes using planetary nebulae
L. Coccato, O. Gerhard, M. Arnaboldi +11
We present new planetary nebulae (PNe) positions, radial velocities, and magnitudes for 6 early-type galaxies obtained with the Planetary Nebulae Spectrograph, their two-dimensiona…
Probing the kinematics of early-type galaxy halos using planetary nebulae
L. Coccato, O. Gerhard, M. Arnaboldi +11
We present first results of a study of the halo kinematics for a sample of early type galaxies using planetary nebulae (PNe) as kinematical tracers. PNe allow to extend up to sever…
The PN.S Elliptical Galaxy Survey: the dark matter in NGC 4494
N. R. Napolitano, A. J. Romanowsky, L. Coccato +12
We present new Planetary Nebula Spectrograph observations of the ordinary elliptical galaxy NGC 4494, resulting in positions and velocities of 255 PNe out to 7 effective radii (25…
VIMOS-VLT Integral Field Kinematics of the Giant Low Surface Brightness Galaxy ESO 323-G064
L. Coccato, R. A. Swaters, V. C. Rubin +2
Aims:We have studied the bulge and the disk kinematics of the giant low surface brightness galaxy ESO 323-G064 in order to investigate its dynamical properties and the radial mass…
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…
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…
