-Changes in SFR due to Radius and Density-

I found that SFR in a cluster increases in the intermediate radii of the cluster, and decreases at the edges and center of the cluster. This could be due to multiple factors. At the center of a cluster, there is a lower concentration of cool gas available to form stars,  and also because of ram-pressure stripping, which occurs when an object (galaxy) enters a more fluid environment (cool gas in a cluster) and said environment strips away gas from the object, producing a lack of star formation. Also, in both the center and the edge of the cluster, an effect called ‘galaxy harassment’ occurs and stunts SFR. This occurrence is due to the gravitational effects of high density galaxies ‘harassing’ each other, preventing cool gas from condensing to form stars.

-Difference in SFRs of Cluster and Field Galaxies-

It was found that galaxies in clusters had a lower star formation rate overall than those who were not in clusters. This is likely due to density: since decreased density in the cluster meant more star formation (excluding the rare case of a starburst galaxy), field galaxies were of the lowest density, and thus had higher SFRs.
