The weight of light: colliding pulses of radiation in General Relativity
Jorge Expósito Patiño, Vitor Cardoso, Hannes R. Rüter
We study the gravitational interaction of very strong pulses of electromagnetic radiation, up to and beyond gravitational collapse. We demonstrate the existence of very compact sta…
Gravitational-wave tails and memory effect for mergers in astrophysical environments
Qassim Alnasheet, Vitor Cardoso, Francisco Duque +1
Gravitational waves from the coalescence of compact objects carry information about their dynamics and the spacetime in regions where they are evolving. In particular, late-time ta…
Black hole spectroscopy in environments: detectability prospects
Thomas F. M. Spieksma, Vitor Cardoso, Gregorio Carullo +2
The ringdown phase following a binary black hole coalescence is a powerful tool for measuring properties of the remnant black hole. Future gravitational wave detectors will increas…
Late-time tails in nonlinear evolutions of merging black holes
Marina De Amicis, Hannes Rüter, Gregorio Carullo +17
We uncover late-time gravitational-wave tails in fully nonlinear 3+1 dimensional numerical relativity simulations of merging black holes, using the highly accurate SpEC code. We ac…
Ringdown Analysis of Rotating Black Holes in Effective Field Theory Extensions of General Relativity
Simon Maenaut, Gregorio Carullo, Pablo A. Cano +4
Quasinormal modes of rapidly rotating black holes were recently computed in a generic effective-field-theory extension of general relativity with higher-derivative corrections. We…
