Abstract

Aims. We report the discovery of a radio minihalo in RXC J1504.1-0248, a massive galaxy cluster that has an extremely luminous cool core. To date, only 9 radio minihalos are known, thus the discovery of a new one in one of the most luminous cool-core clusters provides important information on this peculiar class of sources and sheds light on their origin.
