ENISALA. II. Distinct Star Formation and Active Galactic Nucleus Activity in Merging and Relaxed Galaxy Clusters

Authors: Andra Stroe, and David Sobral

2021 The Astrophysical Journal 912 55.

Provider: AAS Journals

Caption: Figure 18.

Fraction of targets powered by each ionization source, binned by EW. The samples are matched in Hα luminosity. At the lowest EWs <10 Å, the emission is powered by AGNs, at a higher rate in merging clusters compared to relaxed clusters. Beyond 10 Å, the emission is powered by pure SF in 70%–80% of cases.
