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…
Radio continuum observations of the candidate supermassive black hole in the dwarf elliptical VCC128
Pieter Buyle, Sven De Rijcke, Victor P. Debattista +4
The presence of black holes (BHs) at the centers of dwarf elliptical galaxies (dEs) has been argued both theoretically and observationally. Using archival HST/WFPC2 data, we found…
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…
Structure and dynamics of galaxies with a low surface brightness disc. I. The stellar and ionised-gas kinematics
A. Pizzella, E. M. Corsini, M. Sarzi +5
(abridged) Photometry and long-slit spectroscopy are presented for a sample of 6 galaxies with a low surface brightness stellar disc and a bulge. The stellar and ionised-gas kinema…
The pseudobulge of NGC 1292
L. Morelli, E. Pompei, A. Pizzella +6
The photometric and kinematic properties of Sb NGC 1292 suggest it hosts a pseudobulge. The properties of the stellar population of such a pseudobulge are consistent with a slow bu…
The Binary Nucleus in VCC 128: A Candidate Supermassive Black Hole in a Dwarf Elliptical Galaxy
Victor P. Debattista, Ignacio Ferreras, Anna Pasquali +3
{\it Hubble Space Telescope} (\hst) Wide Field Planetary Camera 2 ({\it WFPC2}) images of the Virgo Cluster dwarf elliptical galaxy VCC 128 reveal an apparently double nucleus. The…
