Poincaré asymptotic expansion in black hole theory
Giampiero Esposito, Marco Refuto
In studying the dynamics of fields in black hole theory, the method of separation of variables makes it possible to isolate the radial part of the full solution in many important p…
Superdilations at Schwarzschild null infinity
Marco Refuto
Relying on the definition of asymptotic conformal Killing horizons, the generators of asymptotic conformal symmetries at future null infinity in Schwarzschild space-time are consid…
New perspectives on the irregular singular point of the wave equation for a massive scalar field in Schwarzschild spacetime
Giampiero Esposito, Marco Refuto
For a massive scalar field in a fixed Schwarzschild background, the radial wave equation obeyed by Fourier modes is first studied. After reducing such a radial wave equation to its…
DSR-relativistic spacetime picture and the phenomenology of Planck-scale-modified time dilation
Giovanni Amelino-Camelia, Giulia Gubitosi, Pietro Pellecchia +2
The most active area of research in quantum-gravity phenomenology investigates the possibility of Planck-scale-modified dispersion relations, focusing mainly on two alternative sce…
