Cosmological constraints from the Planck cluster catalogue with DES shear profiles and Chandra observations

We present cosmological constraints from the PSZ2 cosmological cluster sample, using weak-lensing shear profiles from Dark Energy Survey (DES) data and X-ray observations from the telescope for the mass calibration. We compute hydrostatic mass estimates for all clusters in the PS...

Matter scale field: cosmological redshift from evolving material standards

Abstract We formulate Matter Scale Field (MSF) as a relativistic framework in which a homogeneous scalar field controls the evolution of the physical metric and material standards through one common scale. Cosmological redshift is interpreted as a comparison between propagated li...
