Synergy of SDSS and WISE in Stripe 82
Abstract
We report the current results from our effort to synergize WISE and SDSS in the ~300 square degree Stripe 82 region. Using the SDSS images as the prior, we fit the SDSS-detected objects to the WISE W1/W2 images to obtain consistent optical-to-IR SEDs. The major outcome consists of three catalogs: (1) the "SDSS+WISE" photometric catalog of ~13 million SDSS-detected point sources, (2) the "SDSS+WISE" photometric catalog of ~15 million galaxies with photometric redshifts, and (3) the catalog of "WISE Optical Dropouts", or "WoDrops", which are those detected in the W1/W2 images but do not have counterparts in the SDSS. We discuss the application of the extragalactic catalogs in the context of Global Stellar Mass Density and Cosmic Star Formation History.
