CHEX-MATE: AMALGAM weak-lensing analysis of 41 Planck Sunyaev--Zel'dovich-selected galaxy clusters

We present a weak-lensing shear analysis of 41 =3.53 Sunyaev--Zel'dovich (SZ)-selected galaxy clusters at 0.11 łe z łe 0.55 from the CHEX-MATE sample, using wide-field Subaru/Suprime-Cam and CFHT/MegaPrime imaging from the project. The azimuthally averaged weak-lensing signal, me...

Euclid: The linear-construction covariance and cosmology

We study the properties of galaxy cluster two-point correlation function covariance matrices estimated using the linear-construction (LC) method, which is computationally up to 20 times faster than the standard sample-covariance method. Our goal is to assess how well the LC metho...
