1. The Sloan Digital Sky Survey: Technical SummaryThe Astronomical Journal · 2000 · 10,418 citations

   The Sloan Digital Sky Survey (SDSS) will provide the data to support detailed investigations of the distribution of luminous and nonluminous matter in the universe: a photometrically and astrometrically calibrated digital imaging survey of π sr above about Galactic latitude…

2. THE SEVENTH DATA RELEASE OF THE SLOAN DIGITAL SKY SURVEYThe Astrophysical Journal Supplement Series · 2009 · 5,370 citations

   This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDSS-II. It includes 11,663 deg 2 of imaging…

3. The host galaxies of active galactic nucleiMonthly Notices of the Royal Astronomical Society · 2003 · 3,997 citations

   We examine the properties of the host galaxies of 22 623 narrow-line active galactic nuclei (AGN) with 0.02 < z < 0.3 selected from a complete sample of 122 808 galaxies from the Sloan Digital Sky Survey. We focus on…

4. The Origin of the Mass‐Metallicity Relation: Insights from 53,000 Star‐forming Galaxies in the Sloan Digital Sky SurveyThe Astrophysical Journal · 2004 · 3,621 citations

   We utilize Sloan Digital Sky Survey imaging and spectroscopy of ~53,000 star-forming galaxies at z ~ 0.1 to study the relation between stellar mass and gas-phase metallicity. We derive gas-phase oxygen abundances and stellar masses using new techniques that make…
