Summary: We provide a new scaling relation between YSZ, the integrated Sunyaev-Zeldovich signal and M500YX, the cluster mass derived from X-ray observations, using a sample of clusters from the Planck Early Sunyaev-Zeldovich (ESZ) catalogue observed in X-rays by Chandra, and compare it to the results of the Planck collaboration obtained from XMM-Newton observations of a subsample of the ESZ. We derived to the full Planck cosmological cluster sample. We also provide constraints with a redshift evolution of the scaling relation fitted from the data instead of fixing it to the self-similar value.
Products:
  • Chandra calibrated scaling relation (Fig 5 red): chain
  • XMM scaling with new bias (Fig 5 blue): chain

Summary: We present cosmological constraints from the Planck PSZ2 cosmological cluster sample, using weak-lensing shear profiles from Dark Energy Survey (DES) data and X-ray observations from the Chandra telescope for the mass calibration.

  • Constraints obtained for the BCG 800 bpz (Fig 2 green) : chains (tar.gz)
  • Constraints obtained with the bias evolution with mass (Fig4 blue) : chains (tar.gz)
