HST 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 کاملDynamical 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 کاملStructural Parameters for Globular Clusters in NGC 5128. II: HST/ACS Imaging and New Clusters
We report the first results from an imaging program with the ACS camera on HST designed to measure the structural characteristics of a wide range of globular clusters in NGC 5128, the nearest giant elliptical galaxy. From 12 ACS/WFC fields, we have measured a total of 62 previously known globular clusters and have discovered 69 new high-probability cluster candidates not found in any previous
متن کاملHST observations of the metal rich globular clusters NGC 6496 and NGC 6352 ?
Deep exposures of the metal-rich globular clusters NGC6496 and NGC6352 were obtained with the WFPC2 camera on board the Hubble Space Telescope (HST) through the F606W and F814W filters. The resulting colour-magnitude diagrams (CMD) reach down to absolute magnitude M814 ' 10− 10.5, approximately 5 magnitudes below the main sequence (MS) turn-off (TO). The MS of the two clusters are sharp and wel...
متن کاملHst Photometry of the Globular Cluster M4
This paper presents a detailed description of the acquisition and processing of a large body of imaging data for three fields in the globular cluster M4 taken with the Wide Field and Planetary Camera 2 aboard the Hubble Space Telescope. Analysis with the ALLFRAME package yielded the deepest photometry yet obtained for this cluster. The resulting data-set for 4708 stars (positions and calibrated...
