The MagE Spectrograph
J. L. Marshall, Scott Burles, Ian B. Thompson +11
The Magellan Echellette (MagE) spectrograph is a single-object optical echellette spectrograph for the Magellan Clay telescope. MagE has been designed to have high throughput in th…
CS22964-161: A Double-Lined Carbon- and s-Process-Enhanced Metal-Poor Binary Star
Ian B. Thompson, Inese I. Ivans, Sara Bisterzo +6
A detailed high-resolution spectroscopic analysis is presented for the carbon-rich low metallicity Galactic halo object CS 22964-161. We have discovered that CS 22964-161 is a doub…
Active Optics on the Baade 6.5-m (Magellan I) Telescope
Paul L. Schechter, Greg Burley, Charles L. Hull +5
The Magellan active optics system has been operating continuously on the Baade 6.5-m since the start of science operations in February 2001. The active optical elements include the…
Cluster AgeS Experiment: The Age and Distance of the Globular Cluster omega Centauri Determined from Observations of the Eclipsing Binary OGLEGC17
I. B. Thompson, J. Kaluzny, W. Pych +5
We use masses, radii, and luminosities of the detached eclipsing binary OGLEGC17 derived from photometric and spectroscopic observations to calculate the age and distance of the gl…
CTQ 839: Candidate for the Smallest Projected Separation Binary Quasar
Nicholas D. Morgan, Greg Burley, Edgardo Costa +6
We report the discovery of the new double quasar CTQ 839. This B = 18.3, radio quiet quasar pair is separated by 2.1" in BRIH filters with magnitude differences of delta m_B = 2.5,…
First results from the UBC etch-alignment mosaic CCD
S. C. Chapman, G. S. Burley, G. A. H. Walker
First imaging results are obtained with a new CCD mosaic prototype (3K x 3k, 15 μm pixels). The CCDs are aligned using an etched socket alignment technique. Three different measure…
