Globular Clusters in Early-Type Galaxies with GMOS
Terry Bridges, Mike Beasley, Favio Faifer +6
We present recent results from our long-term Gemini/GMOS study of globular clusters in early-type galaxies. To date, we have obtained photometry and spectroscopy for clusters in NG…
VLT spectroscopy of globular cluster in NGC 3115
Harald Kuntschner, Bodo L. Ziegler, R. M. Sharples +2
We present results derived from VLT-FORS2 spectra of 17 globular clusters associated with the nearby lenticular galaxy NGC3115. Comparing line-strength indices to new stellar popul…
Intracluster Planetary Nebulae in the Virgo Cluster
K. C. Freeman, M. Arnaboldi, M. Capaccioli +8
We briefly describe the properties of the confirmed spectroscopic sample of intracluster planetary nebulae recently discovered in the Virgo cluster. We find 23 bonafide intracluste…
The Southern SHARC Survey: the z = 0.3 - 0.7 Cluster XLF
D. J. Burke, C. A. Collins, R. M. Sharples +3
We present the z = 0.3 - 0.7 cluster X-ray luminosity function (XLF) determined from the Southern SHARC (Serendipitous High-redshift Archival ROSAT Cluster) survey. Over the lumino…
A search for distant X-ray galaxy clusters
D. J. Burke, C. A. Collins, R. C. Nichol +4
We report on the progress of our search for serendipitous distant X-ray galaxy clusters in the ROSAT PSPC pointed observations archive. The initial aim of our work is to measure th…
