Exploring the dark sector through galaxy dynamics in clusters

Abstract Galaxy clusters are among the most powerful laboratories to probe fundamental physics, from the formation of cosmic structures to the nature of dark matter, dark energy, and gravity. Realizing their full potential requires accurate and unbiased determinations of their ma...

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...
