The Milky Way Tomography with SDSS: II. Stellar Metallicity
Zeljko Ivezic, Branimir Sesar, Mario Juric +50
Using effective temperature and metallicity derived from SDSS spectra for ~60,000 F and G type main sequence stars (0.2<g-r<0.6), we develop polynomial models for estimating these…
The Sloan Digital Sky Survey-II Supernova Survey: Technical Summary
Joshua A. Frieman, B. Bassett, A. Becker +98
The Sloan Digital Sky Survey-II (SDSS-II) has embarked on a multi-year project to identify and measure light curves for intermediate-redshift (0.05 < z < 0.35) Type Ia supernovae (…
The Hercules-Aquila Cloud
V. Belokurov, N. W. Evans, E. F. Bell +23
We present evidence for a substantial overdensity of stars in the direction of the constellations of Hercules and Aquila. The Cloud is centered at a Galactic longitude of about 40…
Cats and Dogs, Hair and A Hero: A Quintet of New Milky Way Companions
V. Belokurov, D. B. Zucker, N. W. Evans +31
We present five new satellites of the Milky Way discovered in Sloan Digital Sky Survey (SDSS) imaging data, four of which were followed-up with either the Subaru or the Isaac Newto…
