Detection of Cosmic Magnification with the Sloan Digital Sky Survey: R. Scranton, et al... - 0 views

  •  
    This paper studies the change in number density of quasars with distance from bright galaxies and models the results as a gravitational lensing signal from the bright galaxies. It includes a discussion of the potential systematic errors in the measurements and why previous attempts at making this measurement were limited by the systematic errors. (A)

  •  
    This paper discusses the impact on cosmological-parameter measurement from cosmic-shear surveys owing to a variety of systematic errors. Of particular importance are the intrinsic alignments of galaxy shapes (prior to their being lensed) and the accuracy with which the lensed-galaxies redshifts can be estimated from their colors alone.
