GUEST: Gravitational Universe Exploration with Satellite Tracking. A passive satellite laser-ranging mission for the dark gravitational Universe

Diego Blas, Aurélien Hees, F. Javier Atapuerca +78

GUEST is a space mission concept whose central objective is the detection of gravitational waves (GWs) in the microhertz band -- a physics-rich frequency window that no other prese…

Hamiltonian formalism, master functions and Darboux transformations for perturbed (interiors and exteriors of) nonrotating black holes

Michele Lenzi, Guillermo A. Mena Marugán, Andrés Mínguez-Sánchez +1

Motivated by their relevance to the interior of nonrotating black holes, classical and quantum Kantowski-Sachs cosmologies have recently attracted increasing attention. This intere…

Master variables and Darboux symmetry for axial perturbations of the exterior and interior of black hole spacetimes

Michele Lenzi, Guillermo A. Mena Marugán, Andrés Mínguez-Sánchez +1

Recent efforts have shown that Kantowski-Sachs spacetime provides a useful framework for analyzing perturbations inside a Schwarzschild black hole (BH). In these studies, the adopt…

Asymptotics and Universality in Black Holes: from the quasinormal Weyl's law to the binary merger waveform

José Luis Jaramillo, Lamis Al Sheikh, Jérémy Besson +7

Current state-of-the-art approaches to black hole (BH) dynamics, encompassing several effective approximation schemes, offer a remarkable control of the quantitative aspects of str…
