Octupolar bremsstrahlung waveform up to the two-loop level and the third-and-a-half post-Newtonian accuracy
Donato Bini, Thibault Damour, Andrea Geralico
Extending our recent work (which focussed on the even-parity quadrupolar part of the waveform), we compute the even-parity octupolar contribution, , to the gravitational wavef…
Radiated Energy Spectrum, Radiated Angular Distribution and Non-linear Memory from the One-loop Gravitational Bremsstrahlung Waveform
Donato Bini, Thibault Damour, Stefano De Angelis +1
The frequency-domain gravitational waveform emitted by the scattering of two non-spinning massive particles has recently been derived at next-to-leading, \textit{i.e.} one-loop, po…
Bekenstein-Hawking temperature from the Schwarzian
Donato Bini, Giampiero Esposito
Hawking's original derivation of particle creation by black holes in Schwarzschild spacetime exploits, among various concepts, the exponential dependence on the retarded time varia…
Quadrupolar bremsstrahlung waveform at the third-and-a-half post-Newtonian accuracy
Donato Bini, Thibault Damour, Andrea Geralico
We study the quadrupolar part of the gravitational waveform (encoded in the helicity-( radiative quadrupole moment $U_2 = \frac{1}{2!} \bar m^{i} \bar m^{j } U_{i j}…
