| Abstract: |
We present the status of the AKARI Mission Program on the evolution of cluster of galaxies, CLEVL. In order to understand the evolution of galaxies in cluster environment, we have conducted an AKARI imaging survey of galaxy clusters over a wide redshift range. For 8 low redshift clusters (z < 0.3), we performed 2-24 micron imaging in 6 passbands. For intermediate redshift clusters (0.3 < z < 1.3), we have examined the galaxy properties, and the environmental effect by conducting deep NIR-MIR imaging. For high redshift clusters (z > 1.3), we have imaged fields around radio or submm galaxies looking for signs of over-densities. Our program covers a large scale (∼ 5 Mpc) over each target, enabling us to investigate the interaction of cluster members and its surrounding environment. The multi-wavelength capability enables us to use the same MIR star formation indicator over 0 < z < 3 for a consistent estimate of the star formation rate, and to study dust emission from circumstellar disks. |
