All Order Gravitational Wave Tails from Classical Soft Theorem for Subleading Post-Newtonian Expansion

The low-frequency gravitational waveform emitted in a classical scattering process contains an infinite tower of late- and early-time tail terms of the form $u^{-r}(\ln|u|)^{r-1}$, $r \geq 1$. In the Newtonian limit, the coefficients of this entire tower have recently been shown to be universal, i.e. fixed by the asymp...
