Towards a novel wave-extraction method for numerical relativity
Andrea Nerozzi, Marco Bruni, Lior M. Burko +1
We present the recent results of a research project aimed at constructing a robust wave extraction technique for numerical relativity. Our procedure makes use of Weyl scalars to ac…
Transverse frames for Petrov type I spacetimes: a general algebraic procedure
Virginia Re, Marco Bruni, David R. Matravers +1
We develop an algebraic procedure to rotate a general Newman-Penrose tetrad in a Petrov type I spacetime into a frame with Weyl scalars and equal to zero, assumin…
Multimessenger Science Reach and Analysis Method for Common Sources of Gravitational Waves and High-energy Neutrinos
Bruny Baret, Imre Bartos, Boutayeb Bouhou +23
We present the baseline multimessenger analysis method for the joint observations of gravitational waves (GW) and high-energy neutrinos (HEN), together with a detailed analysis of…
Higher order corrections to lensing parameters for extended gravitational lenses
Salvatore Capozziello, Virginia Re
We discuss the contribution to the characteristic lensing quantities, i.e. the deflection angle and Einstein radius, due to the higher order terms (e.g. the gravitomagnetic terms)…
Regression of Environmental Noise in LIGO Data
Vaibhav Tiwari, Marco Drago, Valery Frolov +8
We address the problem of noise regression in the output of gravitational-wave (GW) interferometers, using data from the physical environmental monitors (PEM). The objective of the…
Towards a wave-extraction method for numerical relativity: IV. Testing the quasi-Kinnersley method in the Bondi-Sachs framework
Andrea Nerozzi, Marco Bruni, Virginia Re +1
We present a numerical study of the evolution of a non-linearly disturbed black hole described by the Bondi--Sachs metric, for which the outgoing gravitational waves can readily be…
