Abstract (from CDS):

The possibly unbiased selection process in surveys of the Sunyaev Zel'dovich effect can unveil new populations of galaxy clusters. We performed a weak lensing analysis of the PSZ2LenS sample, i.e. the PSZ2 galaxy clusters detected by the Planck mission in the sky portion covered by the lensing surveys CFHTLenS and RCSLenS. PSZ2LenS consists of 35 clusters and it is a statistically complete and homogeneous subsample of the PSZ2 catalogue. The Planck selected clusters appear to be unbiased tracers of the massive end of the cosmological haloes. The mass-concentration relation of the sample is in excellent agreement with predictions from the L cold dark matter model. The stacked lensing signal is detected at 14s significance over the radial range 0.1 < R < 3.2 Mpc h–1, and is well described by the cuspy dark halo models predicted by numerical simulations. We confirmed that Planck estimated masses are biased low by bSZ = 27 ± 11(stat) ± 8(sys) per cent with respect to weak lensing masses. The bias is higher for the cosmological subsample, bSZ = 40 ± 14(stat) ± 8(sys) per cent.
