Variable stars in the globular cluster M28 (NGC 6626)
G. Prieto, M. Catelan, R. Contreras Ramos +3
We present a new search for variable stars in the Galactic globular cluster M28 (NGC 6626). The search is based on a series of BVI images obtained with the SMARTS Consortium's 1.3m…

Cerro Las Campanas located at Las Campanas Observatory (LCO) in Chile has been selected as the site for the Giant Magellan Telescope. We report results obtained since the commencem…
Seeing, Wind and Outer Scale Effects on Image Quality at the Magellan Telescopes
David J. E. Floyd, Jo Thomas-Osip, Gabriel Prieto
We present an analysis of the science image quality obtained on the twin 6.5 metre Magellan telescopes over a 1.5 year period, using images of ~10^5 stars. We find that the telesco…
The Globular Cluster NGC 5286. II. Variable Stars
M. Zorotovic, M. Catelan, H. A. Smith +18
We present the results of a search for variable stars in the globular cluster NGC 5286, which has recently been suggested to be associated with the Canis Major dwarf spheroidal gal…
A Search for EHB Pulsators in the Globular Cluster NGC 6752
M. Catelan, G. E. Prieto, M. Zoccali +8
We describe the status of a project whose main goal is to detect variability along the extreme horizontal branch of the globular cluster NGC 6752. Based on Magellan 6.5m data, prel…
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…
