Here, we present an X-ray observation ($\\sim$30 ks of cleaned XMM-Newton/EPIC exposure) of this system, allowing us for the first time a detailed comparison between the thermal and non-thermal components of its intragroup medium (IGrM). Remarkably, we find that the radio-to-X-ray luminosity ratio is among the highest ever observed f","authors_text":"A. Simionescu, F. Mernier, H. B\\\"ohringer, J. Bagchi, J. Jacob, N. Werner, S. W.
