"Gravitational radiation from ultra-relativistic collisions: ZFL and beyond"
Abstract: I will present recent (and very recent) work on gravitational bremsstrahlung from ultra-relativistic collisions. After recovering the well known zero-frequency limit (ZFL) I will derive its sub- and sub-sub-leading corrections for a generic ultra relativistic process. Finally, after specializing to the case of two-body collisions, I will try to match the results with those previously obtained, at higher frequency and small deflection angle, by completely different techniques.
