摘要：
Radio haloes are rarely found in galaxy clusters with cooling flows, and those that are found are different from the canonical haloes such as that in the Coma cluster. I propose that the big cluster radio haloes are transient, being formed in large cluster mergers and then fading. The small haloes in cooling flows are a result of magnetic field compression and reacceleration of old relativistic electrons by the cooling flow.
