.:Introduction and Problem:.

What different environmental or internal conditions in a galaxy cluster can affect the SFR, when compared against the SFRs of galaxies not in clusters? How has the average SFR of a cluster galaxy changed over the course of different redshifts? The Star Formations Rates of galaxy clusters have been extensively studied both in close and far redshifts, but those of intermediate redshifts have yet to be observed to the same extent. Three intermediate redshift galaxy clusters of differing masses and states of equilibrium were observed using the Spitzer Space Telescope as well as other data taken from the Hubble Space Telescope. By studying the 24-micron flux, the SFR was derived for each galaxy as well as for the entire cluster. The 24-micron flux will give a more accurate representation of the SFR because the light emitted by young, blue stars is absorbed by the dust and re-radiated at longer wavelengths (the infrared). In optical wavelengths, there is a large amount of light extinction from dust, thus making it difficult to get an accurate reading of SFR.
