cds-question@unistra.frgalaxy-clustersinfrared-photometrygalaxiesinfrared-sourcesredshiftedGalaxy clusters provide powerful laboratories for the study of galaxy evolution, particularly the origin of correlations of morphology and star formation rate (SFR) with density. We construct visible to MIR spectral energy distributions of galaxies in eight low-redshift (z<0.3) clusters and use them to measure stellar masses and SFRs as a function of environment. A partial correlation analysis indicates that the SFRs of star-forming galaxies (SFGs) depend strongly on M_*_ (>99% confidence) with no dependence on R/R_200_ or projected local density at fixed mass. A merged sample of galaxies from the five best measured clusters shows <SFR>{prop.to}(R/R_200_)^1.1+/-0.3^ for galaxies with R/R_200_<=0.4. A decline in the fraction of SFGs toward the cluster center contributes most of this effect, but it is accompanied by a reduction in <SFR> for SFGs with R<=0.1R_200_. The increase in the fraction of SFGs toward larger R/R_200_ and the isolation of SFGs with reduced SFRs near the cluster center are consistent with the truncation of star formation by ram-pressure stripping, as is the tendency for more massive SFGs to have higher SFRs. We conclude that stripping is more likely than slower processes to drive the properties of SFGs with R<0.4R_200_ in clusters. We also find that galaxies near the cluster center are more massive than galaxies farther out in the cluster at ~3.5{sigma}, which suggests that dynamical relaxation significantly impacts the distribution of cluster galaxies as the clusters evolve.2012ApJ...761..114Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/761/114CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-2014)J/ApJS/199/22 : UV-FIR photometry of galaxies (Hernandez-Fernandez+, 2012)J/MNRAS/425/1215 : Multiwavelength survey of AGNs (Klesman+, 2012)J/ApJ/729/22 : Paper I: SEDs of galaxy cluster members (Atlee+, 2011)J/ApJ/713/970 : Low-resolution SED templates for galaxies (Assef+, 2010)J/A+A/486/9 : Redshifts in z~0.25 clusters (Verdugo+, 2008)J/A+A/477/55 : ACO 1825 and AC 114 EROs photometry (Hempel+, 2008)J/ApJ/664/761 : BVRI photometry of AGNs in clusters (Martini+, 2007)J/MNRAS/379/867 : BCG C4 cluster catalog (Von Der Linden+, 2007)J/ApJS/122/51 : 10 rich galaxy clusters spectroscopic cat.
