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}…
Projective path to points at infinity in spherically symmetric spacetimes
Donato Bini, Giampiero Esposito
This paper proves that, in a four-dimensional spherically symmetric spacetime manifold, one can consider coordinate transformations expressed by fractional linear maps which give r…
Nariai spacetime: orbits, scalar self force and Poynting-Robertson-like external force
Donato Bini, Giampiero Esposito
After studying properties of the Nariai solution, including its geodesics, in spherical and de Sitter coordinates, two kinds of accelerated motion are investigated in detail: eithe…
