The Evolving Structure of Galactic Disks
Hugo Martel, Chris Brook, Sean McGee +2
Observations suggest that the structural parameters of disk galaxies have not changed greatly since redshift 1. We examine whether these observations are consistent with a cosmolog…
Vegetation's Red Edge: A Possible Spectroscopic Biosignature of Extraterrestrial Plants
Sara Seager, Edwin L. Turner, Justin Schafer +1
Earth's deciduous plants have a sharp order-of-magnitude increase in leaf reflectance between approximately 700 and 750 nm wavelength. This strong reflectance of Earth's vegetation…
Classification and Characterization of Objects from GALEX and SDSS surveys
Luciana Bianchi, M. Seibert, W. Zheng +22
We use the GALEX (Galaxy Evolution Explorer) Medium Imaging Survey (MIS) and All-Sky Imaging Survey (AIS) data available in the first internal release, matched to the SDSS catalogs…
Chandra X-ray Observations of Newly Discovered, z ~ 1 Clusters from the Red-Sequence Cluster Survey
Amalia Hicks, Erica Ellingson, Mark Bautz +3
Observational studies of cluster evolution over moderate redshift ranges (to z ~ 1) are a powerful tool for constraining cosmological parameters, yet a comprehensive knowledge of t…
The Composition of the Sagittarius Dwarf Spheroidal Galaxy and Implications for Nucleosynthesis and Chemical Evolution
Andrew McWilliam, Tammy A. Smecker-Hane
We outline the results of a study of the chemical composition of 14 stars in the Sagittarius dwarf spheroidal galaxy (Sgr dSph). For the Sgr dSph stars with [Fe/H]>-1 the abundance…
