Globular clusters and dwarf galaxies in Fornax - I. Kinematics in the cluster core from multi-object spectroscopy
G. Bergond, E. Athanassoula, S. Leon +6
We acquired radial velocities of a significant number of globular clusters (GCs) on wide fields between galaxies in the nearby Fornax cluster of galaxies, in order to derive their…
Gravitational tidal effects on galactic open clusters
Gilles Bergond, Stephane Leon, Jean Guibert
We have investigated the 2-D stellar distribution in the outer parts of three nearby open clusters: NGC 2287 (=M41), NGC 2516, and NGC 2548 (=M48). Wide-field star counts have been…
Circumnuclear Spiral Arms and Starburst Rings in Magnetized Barred Spiral Galaxies
Yu-Qing Lou, ZuHui Fan, Chi Yuan +1
The Seyfert galaxy NGC 1097 has an extended neutral hydrogen disk, a companion, a prominent bar and a luminous circumnuclear starburst "ring". Magnetic fields as revealed by nonthe…
Dynamics of embedded bars and the connection with AGN. I. ISAAC/VLT stellar kinematics
E. Emsellem, D. Greusard, F. Combes +4
We present new stellar kinematical profiles of four galaxy hosts of active galactic nuclei, using the CO bandhead around 2.3 micron with the ISAAC/VLT spectrograph. We find that th…
Tidal Tails Around 20 Galactic Globular Cluster: Observational Evidence for Gravitational Disk/Bulge Shocking
S. Leon, G. Meylan, F. Combes
Large-field multi-color images of 20 galactic globular clusters are used to investigate the presence of tidal tails around these stellar systems. Field and cluster stars are sorted…
N-body simulations of globular cluster tides
F. Combes, S. Leon, G. Meylan
We present N-body simulations of globular clusters, in orbits around the Galaxy, in order to study quantitatively and geometrically the tidal effects they encounter. The clusters a…
