Globular Cluster Candidates in NGC 891 1
We use deep images taken with the Advanced Camera for Surveys on board the Hubble Space Telescope of the disk galaxy NGC 891, to search for globular cluster candidates. This galaxy has long been considered to be a close analog in size and structure to the Milky Way and is nearly edge-on, facilitating studies of its halo population. These extraplanar ACS images, originally intended to study the ...
متن کاملEvolution of globular cluster systems in three galaxies of the Fornax cluster
We studied and compared the radial profiles of globular clusters and of the stellar bulge component in three galaxies of the Fornax cluster observed with the WFPC2 of the HST. A careful comparative analysis of these distributions confirms that stars are more concentrated toward the galactic centres than globular clusters, in agreement with what was observed in many other galaxies. If the observ...
متن کاملGlobular cluster formation within the Aquarius simulation
The Aquarius project is a very high-resolution simulation capable of resolving the full mass range of potential globular cluster (GC) formation sites. With a particle mass mp = 1.4 × 104 M , Aquarius yields more than 100 million particles within the virial radius of the central halo which has a mass of 1.8 × 1012 M , similar to that of the Milky Way. With this particle mass, dark matter concent...
متن کاملTramp Novae Between Galaxies in the Fornax Cluster : Tracers of Intracluster Light
We report the results of a survey for novae in and between the galaxies of the Fornax cluster. Our survey provides strong evidence that intracluster novae exist and that they provide a useful, independent measure of the intracluster light in Fornax. We discovered six strong nova candidates in six distinct epochs spanning eleven years from 1993 to 2004. The data were taken with the 4m and the 1....
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) ...
