J/A+A/472/111       Centaurus Compact Object Survey          (Mieske+, 2007)

A search for ultra-compact dwarf galaxies in the Centaurus galaxy cluster. Mieske S., Hilker M., Jordan A., Infante L., Kissler-Patig M. <Astron. Astrophys., 472, 111-119 (2007)> =2007A&A...472..111M

We measured spectroscopic redshifts of about 400 compact object candidates with 19.2<V<22.4mag in the central region of the Centaurus galaxy cluster (d=43Mpc), using 3 pointings with The luminosity range of the candidates covers the bright end of the globular cluster (GC) luminosity function and the luminosity regime of UCDs in Fornax and Virgo. Within the area surveyed, our completeness in terms of slit allocation is ∼30%. Description: The data for this publication were obtained in service mode with the VIsible MultiObject Spectrograph VIMOS mounted on UT3 Melipal at the VLT (programme 076.B-0293). VIMOS allows simultaneous observing of 4 quadrants, each of dimension 7'x8', and separated by about 2'. We observed three multi-object spectroscopy (MOS) pointings in the central Centaurus cluster, covering both NGC 4696 and NGC 4709. File Summary:
