TL;DR
This paper explores how the Sunyaev-Zel'dovich (SZ) effect can be used to understand the shape and geometry of galaxy cluster haloes, focusing on multi-wavelength observations and a specific case study.
Contribution
It introduces a method to characterize the geometrical properties of galaxy cluster haloes using SZ signals and multi-wavelength data, with initial observational results.
Findings
Preliminary images from NIKA2 and ALMA show the gas distribution.
The SZ signal provides insights into the shape of galaxy cluster haloes.
Multi-wavelength observations enhance understanding of halo geometries.
Abstract
We present the on-going activity to characterize the geometrical properties of the gas and dark matter haloes using multi-wavelength observations of galaxy clusters. The role of the SZ signal in describing the gas distribution is discussed for the pilot case of the CLASH object MACS J1206.2-0847. Preliminary images of the NIKA2 and ALMA exposures are presented.
