Emerging Hawking-Like Radiation from Gravitational Bremsstrahlung Beyond the Planck Scale

We argue that, as a consequence of the graviton's spin-2, its bremsstrahlung in trans-planckian-energy ($E\gg M_P$) gravitational scattering at small deflection angle can be nicely expressed in terms of helicity-transformation phases and their transfer within the scattering process. The resulti...
