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…
Pseudospectral implementation of the Einstein-Maxwell system
Jorge Expósito Patiño, Hannes R. Rüter, David Hilditch
Electromagnetism plays an important role in a variety of applications in gravity that we wish to investigate. To that end, in this work, we present an implementation of the Maxwell…
The SXS Collaboration's third catalog of binary black hole simulations
Mark A. Scheel, Michael Boyle, Keefe Mitman +56
We present a major update to the Simulating eXtreme Spacetimes (SXS) Collaboration's catalog of binary black hole simulations. Using highly efficient spectral methods implemented i…
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…
Twist-free axisymmetric critical collapse of a complex scalar field
Krinio Marouda, Daniela Cors, Hannes R. Rüter +2
Critical phenomena in gravitational collapse are characterized by the emergence of surprising structure in solution space, namely the appearance of universal power-laws and periodi…
