The Seventh Data Release of the Sloan Digital Sky Survey
K. Abazajian
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 SDS…
Estimating the Redshift Distribution of Photometric Galaxy Samples II. Applications and Tests of a New Method
Carlos E. Cunha, Marcos Lima, Hiroaki Oyaizu +2
In Lima et al. 2008 we presented a new method for estimating the redshift distribution, N(z), of a photometric galaxy sample, using photometric observables and weighted sampling fr…
Discovery of A Very Bright, Strongly-Lensed z=2 Galaxy in the SDSS DR5
Huan Lin, Elizabeth Buckley-Geer, Sahar S. Allam +8
We report on the discovery of a very bright z = 2.00 star-forming galaxy that is strongly lensed by a foreground z=0.422 luminous red galaxy (LRG). This system was found in a syste…
Constraining the Scatter in the Mass-Richness Relation of maxBCG Clusters With Weak Lensing and X-ray Data
Eduardo Rozo, Eli S. Rykoff, August Evrard +10
We measure the logarithmic scatter in mass at fixed richness for clusters in the maxBCG cluster catalog, an optically selected cluster sample drawn from SDSS imaging data. Our meas…
Dark Energy and the Accelerating Universe
Joshua Frieman, Michael Turner, Dragan Huterer
The discovery ten years ago that the expansion of the Universe is accelerating put in place the last major building block of the present cosmological model, in which the Universe i…
Two More Candidate AM Canum Venaticorum (AM CVn) Binaries from the Sloan Digital Sky Survey
S. F. Anderson, A. C. Becker, D. Haggard +18
AM CVn systems are a select group of ultracompact binaries with the shortest orbital periods of any known binary subclass; mass-transfer is likely from a low-mass (partially-)degen…
Average Properties of a Large Sample of z_abs ~ z_em associated Mg II Absorption Line Systems
D. Vanden Berk, P. Khare, D. G. York +16
We have studied a sample of 415 associated (z_ab z_em; relative velocity with respect to QSO <3000km/s) Mg II absorption systems with 1.0<=z_ab<=1.86, in the spectra of SDSS DR3 QS…
Estimating the Redshift Distribution of Faint Galaxy Samples
Marcos Lima, Carlos E. Cunha, Hiroaki Oyaizu +3
We present an empirical method for estimating the underlying redshift distribution N(z) of galaxy photometric samples from photometric observables. The method does not rely on phot…
The Correlation Function of Optically Selected Galaxy Clusters in the Sloan Digital Sky Survey
Juan Estrada, Emiliano Sefusatti, Joshua A. Frieman
We measure the two-point spatial correlation function for clusters selected from the photometric MaxBCG galaxy cluster catalog for the Sloan Digital Sky Survey (SDSS). We evaluate…
A Measurement of the Rate of type-Ia Supernovae at Redshift 0.1 from the First Season of the SDSS-II Supernova Survey
Benjamin Dilday, R. Kessler, J. A. Frieman +50
We present a measurement of the rate of type Ia supernovae (SNe Ia) from the first of three seasons of data from the SDSS-II Supernova Survey. For this measurement, we include 17 S…
