We would like to formally announce that Yale has joined the SDSS-III collaboration. Yale will pay $900K for full institutional membership, which extends through mid-2014.  We are grateful to the Yale Provost's office for providing funding.

Building on the legacy of the Sloan Digital Sky Survey (SDSS) and SDSS-II, the SDSS-III Collaboration is carrying out a program of four surveys to map the structure and dynamics of the Milky Way, to find and characterize extrasolar planetary systems, and to understand dark energy and the nature of the universe.

The four SDSS-III projects are :

BOSS : The Baryon Oscillation Spectroscopic Survey, aiming to measure the expansion rate of the Universe through the baryon oscillation feature in the galaxy distribution

SEGUE-2 : mapping the outer Milky Way with spectra of over 200,000 stars, doubling the sample of the SEGUE component of SDSS-II

APOGEE : The APO Galactic Evolution Experiment (APOGEE) will use high-resolution, high signal-to-noise infrared spectroscopy to survey 100,000 red giant stars across the full range of the Galactic bulge, bar, disk, and halo.

MARVELS : The Multi-object APO Radial Velocity Exoplanet Large-area Survey (MARVELS) will monitor the radial velocities of 11,000 bright stars, with the precision and cadence needed to detect gas giant planets that have orbital periods ranging from several hours to two years.

Detailed descriptions of all of these projects and the SDSS-III collaboration can be found at :

The Yale membership means that any Yale affiliate (faculty, postdoc, graduate student with more than 50% of their salary paid by Yale) has access to all of the SDSS-III projects and data, and may use these for scientific projects (within some broad collaboration rules). Furthermore, the SDSS-III project has and will continue to solicit ancillary projects that can piggyback on the existing spectroscopic survey. Because SDSS-III produces large volumes of calibrated spectroscopic data, it is particularly well suited to research projects for summer students, undergraduates and beginning graduate students.

We believe that SDSS-III is an exciting scientific opportunity for Yale, and look forward to seeing numerous Yale analyses in the future! Nikhil Padmanabhan, Asst. Prof of Physics Meg Urry, Chair of Physics Jeff Kenney, Chair of Astronomy
