In the context of the AdS/CFT correspondence, we discuss the gravity dual of a heavy-ion-like collision in a variant of N = 4 SYM. We provide a gravity dual picture of the entire process by using a model in which the scattering process creates initially a holographic shower in bulk AdS. The subsequent gravitational fall leads to a moving black hole that is gravity dual to the expanding and cooling heavy-ion fireball. The front of the fireball cools at the rate of 1/¥ó while the core cools as 1/¡î¥ó from a cosmological-like argument. The cooling is faster than Bjorken cooling. The fireball freezes when the dual black hole background is replaced by a confining background through the Hawking-Page transition.
