Abstract:

We propose an 80 ks pointed observation of one of the brightest near-by hot and merging galaxy cluster, Triangulum Australis. Recent Suzaku wide-band spectroscopy reveals a very hot (kT >20 keV) thermal component in several merging clusters (RXJ1347, Abell 3667 and so on). On the other hand, relaxed cluster (such as Abell 1060 and Centaurus) show no evidence of such component. These results suggests that the very-hot component is the key aspects of merging cluster. Triangulum Australis is a bright (f ~ 1e-10 cgs), mildly hot (kT ~ 9 keV) and relatively compact (size ~20x20 arcmin2) shaped cluster. ASCA detected a hot region in the center and to the east (Markevitch et al. 1996). Combination of these characteristics makes this cluster the best candidate for our research.
