Evidence of the accelerated expansion of the Universe from weak lensing tomography with... - 0 views

    This paper describes measurements of cosmic shear from a 2 square degree Hubble Space Telescope survey, combined with photometric redshifts of the lensed galaxies. The addition of the photometric redshifts allowed the authors to measure the evolution of the mass power-spectrum, which provides additional information about the cosmological model beyond what the integrated power-spectrum can provide.

Dark energy constraints from cosmic shear power spectra: impact of intrinsic alignments... - 0 views

    This paper discusses the impact on cosmological-parameter measurement from cosmic-shear surveys owing to the intrinsic alignments of galaxy shapes (prior to their being lensed). (A)

    This paper describes measurements of cosmic shear from a 2 square degree Hubble Space Telescope survey, combined with photometric redshifts of the lensed galaxies. The addition of photometric redshifts allowed the authors to produce a three dimensional reconstruction of the mass structures in the field. (A)

Catastrophic photometric redshift errors: weak-lensing survey requirements: G. Bernstei... - 0 views

    This paper discusses the impact on cosmological-parameter measurement from cosmic-shear surveys owing to catastrophic errors in photometric redshifts measurements. (A)

Systematic effects on dark energy from 3D weak shear: T. D. Kitching, A. N. Taylor, A. ... - 0 views

  •  
    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.
