They are throwing relativistic, highly charged gold ions at each other. Then when the gold atoms barely miss, the cloud of insanely high energy photons streaming off of them merge in the area between them. Intensity of photons is going to be start of the universe high. Frequency caused by doppler shift and monstrous energy levels will also be insanely high. At those speeds, the blackbody radiation from a 1 pound rubber duck from your bathtub would be doppler shifted into the gamma range. In addition, due to the velocity of the duck, they would stack up in front of it in a huge wave of such intensity that it would create cosmic background that would herald the arrival of your duck with the intensity of a megaton nuclear bomb.
