Dynamical evolution of globular cluster systems in clusters of galaxies : I . The case of NGC 1404 in the Fornax cluster
We investigate, via numerical simulations, the tidal stripping and accretion of globular clusters (GCs). In particular, we focus on creating models that simulate the situation for the GC systems of NGC 1404 and NGC 1399 in the Fornax cluster, which have poor (specific frequency SN ∼ 2) and rich (SN ∼ 10) GC systems respectively. We initially assign NGC 1404 in our simulation a typical SN (∼ 5) ...
متن کاملExtended stellar kinematics of elliptical galaxies in the Fornax cluster
We present extended stellar kinematics for a sample of elliptical galaxies in the Fornax cluster. FCC 335) have no previously published kinematical data. Major-axis velocity dispersion profiles (VDPs) and rotation curves (RCs) are given for 12 of the galaxies. A major feature of this data is the spatial extension: for 8 galaxies the data extends beyond 1 R e , and for 5 it extends beyond 2 R e....
متن کاملThe Globular Cluster System in the Inner Region of the Giant Elliptical Galaxy Ngc 4472
We present a study of globular clusters in the inner region of the giant elliptical galaxy NGC 4472, based on theHST WFPC2 archive data. We have found about 1560 globular cluster candidates at the galactocentric radius r < 4 arcmin, most of which are located within r = 1.1 arcmin. V − (V − I) diagram of these objects shows a dominant vertical structure which consists obviously of two components...
متن کاملThe Richness of the Globular Cluster System of Ngc 3923: Clues to Elliptical Galaxy Formation
We present new data on the globular cluster system of the elliptical galaxy NGC 3923 which show that it has the most globular clusters per unit luminosity of any noncluster elliptical yet observed, with SN = 6:4 1:4. NGC 3923 is also among the brightest ellipticals outside of a galaxy cluster for which the number of globular clusters has been determined. Our observation of a large number of clu...
متن کاملThe early - type dwarf galaxy population of the Fornax cluster
Aims. We analyse the photometric properties of the early-type Fornax cluster dwarf galaxy population (M V > −17 mag), based on a wide field imaging study of the central cluster area in V and I bandpasses. We used the instrument/telescope combination IMACS/Magellan at Las Campanas Observatory, providing much larger light collecting area and better image resolution than previous wide field imagin...
