Convenient filtering techniques for LIGO strain of the GW150914 event
(IOP Publishing, 2019-04-18)
We present a new strategy for the pre-processing filtering techniques of the LIGO strain of the GW150914 [1,2] event that intends to extract as much physical information as possible, minimizing the use of prior assumptions, ...
Improved upper limits on the stochastic gravitational-wave background from 2009-2010 LIGO and Virgo data
(2014)
Gravitational waves from a variety of sources are predicted to superpose to create a stochastic
background. This background is expected to contain unique information from throughout the history of
the Universe that is ...
Aplicación de nuevas técnicas de filtrado a señales de ondas gravitacionales detectadas por la LIGO/Virgo Collaboration
(2020-07)
En este trabajo se presenta la aplicación de una técnica de preprocesado de señales para el evento de ondas gravitacionales GW170104. Este procedimiento se basa en el uso de filtros FIR, diferenciándose de otras técnicas ...
El interferómetro de Michelson : entre el éter y las ondas gravitacionalesMichelson’s interferometer : between ether and gravitational waves
(Universidad Nacional de QuilmesUniversidad Nacional de Tres de Febrero, 2018-10-01)
En este trabajo se presenta una reconstrucción de dos de los usos experimentales más sobresalientes del interferómetro de Michelson en la historia de la ciencia: la medición del éter (1881,1887) y la detección de las ondas ...
Gravitational radiation from the inspiral of compact binaries based on a Yukawa-type addition to the Newtonian potential
(Universidad Nacional de Colombia - Sede Bogotá, 2020-01-21)
In this work, the gravitational radiation emitted from a compact binary system is analyzed in
the context of general relativity and f(R) gravity based on linearized theory. Besides the two
standard polarizations of ...
Improving our ability to distinguish gravitational-wave signals from detector transient noise for the fourth LIGO-Virgo-KAGRA observing run
(Universidad de los AndesFísicaFacultad de CienciasDepartamento de Física, 2023-07-12)
A pesar de haber alcanzado sensibilidades capaces de detectar la amplitud extremadamente pequeña de las ondas gravitacionales (GWs), los datos de los detectores LIGO y Virgo contienen frecuentes ráfagas de ruido transitorio ...
Possible gravitational radiation detection using the geometric phase of a light beam
(1995)
An effect of geometrical phase shift is predicted for a light beam propagating in the field of a gravitational wave. For the beam travelling orthogonally to the direction of propagation of the gravitational wave from an ...

Cosmic inflation in modified models of gravity and an analysis on gravitational waves
(2021)
This work comprises three different lines of research related to the study of cosmological inflation and the propagation of gravitational waves. In the first issue, we developed -for the first time in a systematic way- the ...
