CFHTLenS: Combined probe cosmological model comparison using 2D weak gravitational lensing by Kilbinger, M, Fu, L, Heymans, C, Simpson, F, Benjamin, J, Erben, T, Harnois-Deraps, J, Hoekstra, H, Hildebrandt, H, Kitching, T, Mellier, Y, Miller, L, Waerbeke, L, Benabed, K, Bonnett, C, Coupon, J, Hudson, M, Kuijken, K, Rowe, B, Schrabback, T, Semboloni, E, Vafaei, S, Velander, M

“…The best constraints from lensing alone are obtained for the small-scale density-fluctuations amplitude sigma_8 scaled with the total matter density Omega_m. For a flat LambdaCDM model we obtain sigma_8(Omega_m/0.27)^0.6 = 0.79+-0.03. …”

CFHTLenS tomographic weak lensing: Quantifying accurate redshift distributions by Benjamin, J, Waerbeke, L, Heymans, C, Kilbinger, M, Erben, T, Hildebrandt, H, Hoekstra, H, Kitching, T, Mellier, Y, Miller, L, Rowe, B, Schrabback, T, Simpson, F, Coupon, J, Fu, L, Harnois-Déraps, J, Hudson, M, Kuijken, K, Semboloni, E, Vafaei, S, Velander, M

“…Combining our results with the above cosmological probes, we find Omega_m=0.2762 \pm 0.0074 and sigma_8=0.802 \pm 0.013.…”

Evidence for the accelerated expansion of the Universe from weak lensing tomography with COSMOS by Schrabback, T, Hartlap, J, Joachimi, B, Kilbinger, M, Simon, P, Benabed, K, Bradač, M, Eifler, T, Erben, T, Fassnacht, C, High, F, Hilbert, S, Hildebrandt, H, Hoekstra, H, Kuijken, K, Marshall, P, Mellier, Y, Morganson, E, Schneider, P, Semboloni, E, Waerbeke, L, Velander, M

“…For a flat LCDM cosmology, we measure sigma_8(Omega_m/0.3)^0.51=0.75+-0.08 from lensing, in perfect agreement with WMAP-5, yielding joint constraints Omega_m=0.266+0.025-0.023, sigma_8=0.802+0.028-0.029 (all 68% conf.). …”

3D Cosmic Shear: Cosmology from CFHTLenS by Kitching, T, Heavens, A, Alsing, J, Erben, T, Heymans, C, Hildebrandt, H, Hoekstra, H, Jaffe, A, Kiessling, A, Mellier, Y, Miller, L, Waerbeke, L, Benjamin, J, Coupon, J, Fu, L, Hudson, M, Kilbinger, M, Kuijken, K, Rowe, B, Schrabback, T, Semboloni, E, Velander, M

“…We use 3D cosmic shear to constrain cosmologies with parameters OmegaM, OmegaB, sigma8, h, ns, w0, wa. For a non-evolving dark energy equation of state, and assuming a flat cosmology, lensing combined with WMAP7 results in h=0.78+/-0.12, OmegaM=0.252+/-0.079, sigma8=0.88+/-0.23 and w=-1.16+/-0.38 using only scales k<=1.5h/Mpc. …”
