Galaxy populations in the Antlia cluster. II. Compact elliptical galaxy candidates
Analia V. Smith Castelli, Favio R. Faifer, Tom Richtler +1
We present a photometric analysis of four galaxies classified as compact elliptical (cE) galaxies in the FS90 Antlia Group catalogue. Only 6 members of this rare type of galaxies a…
The Nature of UCDs: Internal Dynamics from an Expanded Sample and Homogeneous Database
Steffen Mieske, Michael Hilker, Andres Jordan +9
We have obtained high-resolution spectra of 23 ultra-compact dwarf galaxies (UCDs) in the Fornax cluster with -10.4>M_V>-13.5 mag (10^6<M/M_*<10^8), using FLAMES/Giraffe at the VLT…
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…
VLT photometry in the Antlia Cluster: the giant ellipticals NGC 3258 and NGC 3268 and their globular cluster systems
Lilia P. Bassino, Tom Richtler, Boris Dirsch
We present a deep VLT photometry in the regions surrounding the two dominant galaxies of the Antlia cluster, the giant ellipticals NGC 3258 and NGC 3268. We construct the luminosit…
The dark matter halo of NGC 1399 - CDM or MOND?
T. Richtler, Y. Schuberth, M. Hilker +3
Central galaxies in galaxy clusters may be key discriminants in the competition between the cold dark matter (CDM) paradigm and modified Newtonian dynamics (MOND). We investigate t…
Stroemgren metallicity calibration: the m1, b-y relation
A. Calamida, G. Bono, P. B. Stetson +15
We performed a new calibration of the Stroemgren metallicity index m1 based on the b-y color of cluster red giant stars. The current Metallicity-Index-Color relation is not linear…
