多波段觀測以調查星系和星系團的共同演化

We conducted a systematic and homogeneous multi-wavelength investigation of the relationship between the properties of clusters of galaxies and that of member galaxies. The cluster properties are determined using the high spatial resolution X-ray data taken from the Chandra ACIS archive, while the properties of galaxies are characterized based on optical images taken with a large field of view Suprime-Cam on the Subaru 8m telescope at Mauna Kea Observatory in Hawaii. We started the investigation with he relationship between the clusters of galaxies and the brightest cluster galaxies (BCGs), in particular, between the dynamical status of the clusters and the properties of BCGs. Our goal is to help understand the relationship between the BCGs and their host clusters, and between the BCGs and other galaxies, to eventually address a question of the formation and co-evolution of BCGs and clusters of galaxies.
