Physics and Astronomy
Recent Suzaku X-ray observations have revealed hot gas properties of a number of clusters of galaxies out to their virial radii, allowing us to explore regions that was not possible in the past. We will present results of our Suzaku mosaic observations of the nearest non-cool core cluster, the Antlia Cluster, out to its degree-scale virial radius in the East direction. Together with Chandra and XMM-Newton observations, systematic uncertainty caused by background point sources is greatly reduced. Physical properties such as surface brightness and temperature profiles will be presented and compared to theoretical models and other clusters. Implications of our results will be discussed.
