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 کاملHST Imaging of the Globular Clusters in the Fornax Cluster: Color and Luminosity Distributions
We examine the luminosity and B − I color distribution of globular clusters for three early-type galaxies in the Fornax cluster using imaging data from the Wide Field/Planetary Camera 2 on the Hubble Space Telescope. The luminosity functions we derive are in most cases better than 50% complete down to B = 26.6. We find that the color distributions of globular clusters in the central region of N...
متن کاملUltra Compact Objects in the Fornax Cluster of Galaxies: Globular clusters or dwarf galaxies?
The relation between the Ultra Compact Objects (hereafter UCOs) recently discovered in the Fornax cluster (Drinkwater et al. 2000a, Hilker et al. 1999) and the brightest globular clusters associated with the central galaxy NGC 1399 has been investigated. The question was adressed whether the UCOs constitute a distinct population of objects not linked to globular clusters or whether there is a s...
متن کاملGlobular clusters in NGC 5128 ?
We used the Wide Field Planetary Camera 2 aboard the Hubble Space Telescope to search for globular clusters in the inner regions of the nearby giant elliptical galaxy NGC 5128. This galaxy is believed to be the product of a merger between a large elliptical galaxy and a small late-type spiral between 160 and 500 Myr ago. We identified 21 globular cluster candidates and measured their core radii...
متن کاملThe Most Exciting Massive Binary Cluster in Ngc 5128: Clues to the Formation of Globular Clusters
VLT images in BV I are used to identify the ionizing source centered on Sersic 13, the largest HII region of the giant nearby galaxy NGC 5128 with logLHα = 39.6 erg/s. This ionizing source turns out to be a close pair of bright and blue star cluster candidates. Spectroscopy obtained with the Magellan I telescope confirms that these are massive young clusters physically associated with the giant...
