Black hole mergers beyond general relativity: a self-force approach
Ayush Roy, Lorenzo Küchler, Adam Pound +1
Gravitational waves from binary black hole mergers provide a glimpse of gravitational dynamics in its most extreme observable regime, potentially enabling precision tests of genera…
The linearised conformal Einstein field equations around a Petrov-type~D spacetime: the conformal Teukolsky equation
Edgar Gasperin, Rodrigo Panosso Macedo, Justin Feng
While the Teukolsky equation plays a central role in traditional treatments of perturbations of algebraically special spacetimes, its relation to Friedrich's conformal Einstein fie…
Topical Collection-Hyperboloidal Foliations in the Era of Gravitational-Wave Astronomy: From Mathematical Relativity to Astrophysics
David Hilditch, Rodrigo Panosso Macedo, Alex Vañó-Viñuales +1
Editorial introducing the GRG Topical Collection "Hyperboloidal foliations in the era of gravitational-wave astronomy," on hyperboloidal slices. The collection includes contributio…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +70
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…
Quasinormal modes in Kerr spacetime as a 2D Eigenvalue problem
Jamil Assaad, Rodrigo Panosso Macedo
We revisit the computation of quasinormal modes (QNMs) of the Kerr black hole using a numerical approach exploiting a representation of the Teukolsky equation as a elliptic pa…
The Confluent Heun functions in Black Hole Perturbation Theory: a spacetime interpretation
Marica Minucci, Rodrigo Panosso Macedo
This work provides a spacetime interpretation of the confluent Heun functions within black hole perturbation theory (BHPT) and explores their relationship to the hyperboloidal fram…
