Revealing the baryon cycle in Galaxy Clusters: connecting galaxy dynamics and gas thermodynamics using (sub-)mm-wave and optical IFU surveys

TL;DR

This paper discusses the potential of combining wide-field optical IFU surveys with large sub-mm telescopes to better understand the baryon cycle in galaxy clusters by linking galaxy dynamics with gas thermodynamics.

Contribution

It proposes a new observational approach that integrates high-resolution optical and sub-mm data to study the baryon cycle in galaxy clusters.

Findings

Highlights the need for large-area, high-resolution sub-mm observations.

Emphasizes the importance of combining optical and sub-mm surveys.

Suggests this approach will transform understanding of environmental effects on galaxy evolution.

Abstract

Observations in the visible and near infrared are transforming our view of the processes affecting galaxy evolution, much of which is dominated by interactions with the large scale environment. Yet a complete picture is missing, as no corresponding high resolution view of the warm/hot intracluster, circumgalactic, and intergalactic media exists over large areas and a comparably broad range of redshifts. Combined with wide-field optical IFU surveys such as CATARSIS, a large diameter sub-mm telescope with a degree-scale field of view would enable a joint view of galaxy dynamics and gas thermodynamics, transforming our understanding of environmental processes.
