Baryon Acoustic Oscillations in the Ly-α forest of BOSS quasars
Nicolás G. Busca, Timothée Delubac, James Rich +59
We report a detection of the baryon acoustic oscillation (BAO) feature in the three-dimensional correlation function of the transmitted flux fraction in the \Lya forest of high-red…
Luminosity Function from dedicated SDSS-III and MMT data of quasars in 0.7<z<4.0 selected with a new approach
N. Palanque-Delabrouille, Ch. Magneville, Ch. Yeche +25
We present a measurement of the quasar luminosity function in the range 0.68<z<4 down to extinction corrected magnitude g_dered=22.5, using a simple and well understood target sele…
Think Outside the Color Box: Probabilistic Target Selection and the SDSS-XDQSO Quasar Targeting Catalog
Jo Bovy, Joseph F. Hennawi, David W. Hogg +8
We present the SDSS-XDQSO quasar targeting catalog for efficient flux-based quasar target selection down to the faint limit of the Sloan Digital Sky Survey (SDSS) catalog, even at…
A GMBCG Galaxy Cluster Catalog of 55,424 Rich Clusters from SDSS DR7
Jiangang Hao, Timothy A. McKay, Benjamin P. Koester +11
We present a large catalog of optically selected galaxy clusters from the application of a new Gaussian Mixture Brightest Cluster Galaxy (GMBCG) algorithm to SDSS Data Release 7 da…
Lensing Bias in Cosmic Shear
Fabian Schmidt, Eduardo Rozo, Scott Dodelson +2
Only galaxies bright enough and large enough to be unambiguously identified and measured are included in galaxy surveys used to estimate cosmic shear. We demonstrate that because g…
Size Bias in Galaxy Surveys
Fabian Schmidt, Eduardo Rozo, Scott Dodelson +2
Only certain galaxies are included in surveys: those bright and large enough to be detectable as extended sources. Because gravitational lensing can make galaxies appear both brigh…
