Galaxy halo masses and satellite fractions from galaxy-galaxy lensing in the SDSS: stellar mass, luminosity, morphology, and environment dependencies
Rachel Mandelbaum, Uros Seljak, Guinevere Kauffmann +2
The relationship between galaxies and dark matter can be characterized by the halo mass of the central galaxy and the fraction of galaxies that are satellites. Here we present obse…
Detection of large scale intrinsic ellipticity-density correlation from the Sloan Digital Sky Survey and implications for weak lensing surveys
Rachel Mandelbaum, Christopher M. Hirata, Mustapha Ishak +2
The power spectrum of weak lensing shear caused by large-scale structure is an emerging tool for precision cosmology, in particular for measuring the effects of dark energy on the…
The Fourth Data Release of the Sloan Digital Sky Survey
J. K. Adelman-McCarthy et al.
This paper describes the fourth data release of the Sloan Digital Sky Survey (SDSS), including all survey-quality data taken through June 2004. The data release includes five-band…
Ellipticity of dark matter halos with galaxy-galaxy weak lensing
Rachel Mandelbaum, Christopher M. Hirata, Tamara Broderick +2
We present the results of attempts to detect the ellipticity of dark matter halos using galaxy-galaxy weak lensing with SDSS data. We use 2,020,256 galaxies brighter than r=19 with…
Systematic errors in weak lensing: application to SDSS galaxy-galaxy weak lensing
Rachel Mandelbaum, Christopher M. Hirata, Uros Seljak +6
Weak lensing is emerging as a powerful observational tool to constrain cosmological models, but is at present limited by an incomplete understanding of many sources of systematic e…
