First-year Sloan Digital Sky Survey-II (SDSS-II) Supernova Results: Hubble Diagram and Cosmological Parameters (2009)

Kessler, Richard, Becker, Andrew, Cinabro, David, Vanderplas, Jake, Frieman, Joshua A., Marriner, John, ...

We present measurements of the Hubble diagram for 103 Type Ia supernovae (SNe) with redshifts 0.04 < z < 0.42, discovered during the first season (Fall 2005) of the Sloan Digital Sky Survey-II...

First-Year Spectroscopy for the SDSS-II Supernova Survey (2008)

Zheng, Chen, Romani, Roger W., Sako, Masao, Marriner, John, Bassett, Bruce, Becker, Andrew, ...

This paper presents spectroscopy of supernovae discovered in the first season of the Sloan Digital Sky Survey-II Supernova Survey. This program searches for and measures multi-band light curves of...

Exploring the Variable Sky with the Sloan Digital Sky Survey (2007)

Sesar, Branimir, Ivezic, Zeljko, Lupton, Robert H., Juric, Mario, Gunn, James E., Knapp, Gillian R., ...

We quantify the variability of faint unresolved optical sources using a catalog based on multiple SDSS imaging observations. The catalog covers SDSS Stripe 82, and contains 58 million photometric...

Exploring the variable sky with the Sloan Digital Sky Survey (2007)

Sesar, Branimir, Ivezic, Zeljko, Lupton, Robert H., Juric, Mario, Gunn, James E., Knapp, Gillian R., ...

We quantify the variability of faint unresolved optical sources using a catalog based on multiple SDSS imaging observations. The catalog covers SDSS stripe 82, which lies along the celestial equator...

Sloan Digital Sky Survey Standard Star Catalog for stripe 82: the dawn of industrial 1% optical photometry (2007)

Ivezic, Zeljko, Allyn Smith, J., Miknaitis, Gajus, Lin, Huan, Tucker, Douglas, Lupton, Robert H., ...

We describe a standard star catalog constructed using multiple SDSS photometric observations (at least four per band, with a median of 10) in the ugriz system. The catalog includes 1.01 million...

Distributions of Galaxy Spectral Types in the Sloan Digital Sky Survey (2004)

Yip, Ching-Wa, Connolly, Andrew, Szalay, Alex, Budavari, Tamas, SubbaRao, Mark, Frieman, Joshua, ...

We perform an objective classification of 170,000 galaxy spectra in the Sloan Digital Sky Survey (SDSS) using the Karhunen-Lo\`eve (KL) transform. With about one-sixth of the total set of galaxy...
