Slow-then-rapid quenching as traced by tentative evidence for enhanced metallicities of cluster galaxies at z~0.2 in the slow quenching phase

C. Maier, B. L. Ziegler, C. P. Haines +1

(Abridged) We explore 7 clusters from LoCuSS at z~0.2 with spectra of 1965 cluster members from the ACReS Hectospec survey covering a region which corresponds to about three virial…
