GEMINI-GMOS spectroscopy in the Antlia cluster
F. Faifer, A. Smith Castelli, L. P. Bassino +2
We present preliminary results of a spectroscopic study performed in the Antlia cluster through GEMINI-GMOS data. We derived new radial velocities that allow us to confirm the clus…
A common colour-magnitude relation from giant elliptical galaxies to globular clusters?
A. V. Smith Castelli, L. P. Bassino, T. Richtler +3
We discuss the existence of a common colour-magnitude relation (CMR) of metal-poor globular clusters and early-type galaxies, i.e. giant ellipticals, normal ellipticals and lenticu…
Incidence of the host galaxy on the measured optical linear polarization of blazars
I. Andruchow, Sergio A. Cellone, Gustavo E. Romero
We study the incidence of the underlying host galaxy light on the measured optical linear polarization of blazars. Our methodology consists of the implementation of simulated obser…
Galaxy populations in the Antlia cluster. I. Photometric properties of early-type galaxies
A. V. Smith Castelli, L. P. Bassino, T. Richtler +3
We present the first colour-magnitude relation (CMR) of early-type galaxies in the central region of the Antlia cluster, obtained from CCD wide-field photometry in the Washington p…
Unveiling the nature of INTEGRAL objects through optical spectroscopy. VI. A multi-observatory identification campaign
N. Masetti, E. Mason, L. Morelli +18
Using 8 telescopes in the northern and southern hemispheres, plus archival data from two on-line sky surveys, we performed a systematic optical spectroscopic study of 39 putative c…
Extreme photo-polarimetric behaviour of the blazar AO 0235+164
Sergio A. Cellone, Gustavo E. Romero, Jorge A. Combi +1
We present optical photo-polarimetric observations with high temporal resolution of the blazar AO 0235+164. Our data, the first to test the photo-polarimetric behaviour of this obj…
