From Clusters to Proto-clusters: the Infrared Perspective on Environmental Galaxy Evolution [GA]

http://arxiv.org/abs/2209.02781


Environment is one of the primary drivers of galaxy evolution, capable of transforming galaxies from star forming to quiescent via multiple mechanisms. Despite its importance, however, we still do not have a clear view of how environmental quenching proceeds even in the most extreme environments: galaxy clusters and their progenitor proto-clusters. Recent advances in infrared capabilities have enabled transformative progress not only in the identification of these structures but in detailed analyses of quiescence, obscured star formation, and molecular gas in (proto-)cluster galaxies across cosmic time. In this review, we will discuss the current state of the literature regarding the quenching of galaxies in (proto-)clusters from the observational, infrared perspective. Our improved understanding of environmental galaxy evolution comes from unique observables across the distinct regimes of the near-, mid-, and far-infrared, crucial in the push to high redshift where galaxy growth is dominated by highly extincted, infrared-bright galaxies.
