Completing the Census of (Bright) Variable Stars in Galactic Globular Clusters
M. Catelan, H. A. Smith, B. J. Pritzl +15
We present a long-term project aimed at completing the census of (bright) variable stars in Galactic globular clusters. While our main aim is to obtain a reliable assessment of the…

R. Salinas, M. Catelan, H. A. Smith +2
We report the discovery of a sizeable, previously unknown variable star population in the Sagittarius dwarf spheroidal globular clusters NGC 5634, Arp 2 and Terzan 8. Location, pre…

M. Grossi, M. J. Disney, B. J. Pritzl +5
We present HST/WFPC2 observations (F555W, F814W) and ATCA high resolution HI maps of three gas-rich dwarf galaxies in the Centaurus A group discovered in two blind 21-cm surveys (H…
On the Oosterhoff Classification of the Unusual, Metal-Rich Globular Clusters NGC 6388 and NGC 6441
M. Catelan, A. V. Sweigart, B. J. Pritzl +1
We discuss the Oosterhoff classification of the unusual, metal-rich globular clusters NGC 6388 and NGC 6441, on the basis of new evolutionary models computed for a range of metalli…
