Abstract: We analyze the head-on collision of two boosted Schwarzschild black holes and the mass-energy loss of the system by gravitational wave emission, in the realm of Robinson-Trautman (RT) spacetimes. The characteristic initial data for the problem are constructed, and evolved by RT equation integrated by numerical codes based on the Galerkin method. The emission of gravitational waves is typical bremsstrahlung at early times and the final configuration is that of a boosted black hole with larger (Bondi) rest mass and smaller velocity parameter. The efficiency Δ of the process of energy extraction by gravitational radiation is evaluated and satisfies a nonextensive distribution with entropic index q ≃ 1/2. The final momentum of the remnant black hole has a maximum which depends on the ratio of the masses of the initial black holes. [ABSTRACT FROM AUTHOR]
