Description |
I will present 12mm observations of the Bullet cluster from the Australia Telescope Compact Array; in particular, a high angular resolution measurement of the substructure in Sunyaev-Zel'dovich Effect (SZE) and will talk about the discovery of multiple compact SZ features in the Bullet cluster. None of these SZE feature centres corresponds to any bright spot in X-ray, optical or lensing maps. This implies that the gas pressure distribution differs significantly from the distributions in gas emission measure, galaxy and dark matter distributions.
