Regression of Environmental Noise in LIGO Data

Autor: Tiwari, Vaibhav, Drago, Marco, Frolov, Valery, Klimenko, Sergey, Mitselmakher, Guenakh, Necula, Valentin, Prodi, Giovanni, Re, Virginia, Salemi, Francesco, Vedovato, Gabriele, Yakushin, Igor

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 regression analysis is to predict environmental noise in the gravitat

Towards a novel wave-extraction method for numerical relativity

Autor: Nerozzi, Andrea, Bruni, Marco, Burko, Lior M., Re, Virginia

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 achieve wave extraction. It is well known that, with a correct choice of

Transverse frames for Petrov type I spacetimes: a general algebraic procedure

Autor: Re, Virginia, Bruni, Marco, Matravers, David R., White, Frances T.

Publikováno v: Gen.Rel.Grav. 35 (2003) 1351-1363

We develop an algebraic procedure to rotate a general Newman-Penrose tetrad in a Petrov type I spacetime into a frame with Weyl scalars $\Psi_{1}$ and $\Psi_{3}$ equal to zero, assuming that initially all the Weyl scalars are non vanishing. The new f
