Abstract We describe a population of compact objects in the centre of the Fornax Cluster which were discovered as part of our 2dF Fornax Spectroscopic Survey. These objects have spectra typical of old stellar systems, but are unresolved on photographic sky survey plates. They have absolute magnitudes −13 < MB < −11, so they are 10 times more luminous than any Galactic globular clusters, but fainter than any known compact dwarf galaxies. These objects are all within 30 arcminutes of the central… 
Peculiar compact stellar systems in the Fornax cluster
We search for hints to the origin and nature of compact stellar systems in the magnitude range of ultracompact dwarf galaxies in deep wide-field imaging data of the Fornax cluster core. We visually
The evolution and star formation of dwarf galaxies in the Fornax Cluster
We present the results of a spectroscopic survey of 675 bright (16.5 < b(J) < 18) galaxies in a 6 degrees field centred on the Fornax cluster with the FLAIR-II spectrograph on the UK Schmidt
Galaxy Threshing and Ultra-Compact Dwarfs in the Fornax Cluster
We have discovered a new type of galaxy in the Fornax Cluster: `ultra-compact' dwarfs (UCDs). The UCDs are unresolved in ground-based imaging and have spectra typical of old stellar systems. Although
Ultracompact Dwarf Galaxies in the Fornax Cluster
By utilizing the large multiplexing advantage of the Two-degree Field spectrograph on the Anglo-Australian Telescope, we have been able to obtain a complete spectroscopic sample of all objects in a
M32 Analogs? A Population of Massive Ultra-compact Dwarf and Compact Elliptical Galaxies in Intermediate-redshift Clusters
We report the discovery of relatively massive, M32-like ultra compact dwarf (UCD) and compact elliptical (CE) galaxy candidates in $0.2<z<0.6$ massive galaxy clusters imaged by the Cluster Lensing
A Census of Ultra-Compact Dwarf Galaxies in Nearby Galaxy Clusters
Ultra-compact dwarf galaxies (UCDs) are predominatly found in the cores of nearby galaxy clusters. Besides the Fornax and Virgo cluster, UCDs have also been confirmed in the twice as distant Hydra I
We present a detailed analysis of high-resolution two-band Hubble Space Telescope Advanced Camera for Surveys imaging of 21 ultra-compact dwarf (UCD) galaxies in the Virgo and Fornax Clusters. The
A search for ultra-compact dwarf galaxies in the Centaurus galaxy cluster
Aim: To extend the investigations of ultra-compact dwarf galaxies (UCDs) beyond the well studied Fornax and Virgo clusters. Methods: We measured spectroscopic redshifts of about 400 compact object
Velocity dispersion measurements are presented for several of the most luminous globular clusters (GCs) in NGC 5128 (Centaurus A) derived from high-resolution spectra obtained with the UVES echelle
Globular clusters as tracers of the halo assembly of nearby central cluster galaxies
Abstract The properties of globular cluster systems (GCSs) in the core of the nearby galaxy clusters Fornax and Hydra I are presented. In the Fornax cluster we have gathered the largest radial


High surface brightness dwarf galaxies in the Fornax cluster
We describe a search for compact dwarf galaxies in the Fornax cluster using the FLAIR spectrograph on the UK Schmidt Telescope. We measured radial velocities of 453 compact galaxies brighter than B-T
HST Imaging of the Globular Clusters in the Fornax Cluster: NGC 1399 and NGC 1404
A B STR A CT The Fornax cluster galaxies NGC 1399 and NGC 1404 are ideal for studying the effects of a cluster environment on globular cluster systems. Here we present new optical imaging of these
The central region of the Fornax cluster II. Spectroscopy and radial velocities of member and background galaxies
Radial velocities of 94 galaxies brighter than aboutVtot = 20 mag in the direction of the central Fornax cluster have been measured 1 . Except for 8 Fornax mem- bers, all galaxies lie in the
Radial Velocities of Globular Clusters in the Giant Elliptical Galaxy NGC 1399
We report radial velocity measurements for 18 globular clusters and one dE galaxy in the field of the giant elliptical galaxy NGC 1399, the dominant galaxy of the Fornax Cluster. We also present
The fornax spectroscopic survey: the number of unresolved compact galaxies
We describe a sample of 13 bright (18.5 < BJ < 20.1), compact galaxies at low redshift (0.05 < z < 0.21) behind the Fornax Cluster. These galaxies are unresolved on UK Schmidt sky survey plates, and
Dwarf elliptical galaxies
AbstractDwarf elliptical (dE) galaxies, with blue absolute magnitudes typically fainter thanMB=−16, are the most numerous type of galaxy in the nearby universe. Tremendous advances have been made
