A1060_CENTER
We propose XRISM observations of Abell 1060, the brightest and one of the nearest non-cool core/non-merging cluster, suggested by its nearly circular symmetric ICM. There is no strong AGN-jet-ICM interaction and the ICM is likely be "calm". Measuring its bulk flow and turbulence is very important for XRISM, because all cluster PV targets are either cool-core clusters or merging clusters. This observation will provide a baselines for ICM science. By a 100 ks observation at the center, and a 200 ks observation at ~4' offset to the east, we aim to observe a ~100 km/s level of bulk motion and turbulence to the accuracy of < 30 km/s (90% CL). Origin of the newly found soft-radio diffuse source "Flying Fox", and ISM stripping of the spiral galaxy NGC 3312 are also in the scope.
