Implementation of an F-statistic all-sky search for continuous gravitational waves in Virgo VSR1 data
(2014)
We present an implementation of the F -statistic to carry out the first
search in data from the Virgo laser interferometric gravitational wave detector for
periodic gravitational waves from a priori unknown, isolated ...
NIL_004 Summary of session C6: Q&A-everything you wanted to know about gravitational waves but were afraid to ask
(Springer, 2014-10-01)
The paper summarizes the parallel session C6 Q&A-everything you wanted to know about gravitational waves but were afraid to ask of the joint 10th Amaldi Conference on Gravitational Waves and 20th International Conference ...
Gravitational waves from ultra-short period exoplanets

Primordial gravitational waves in running vacuum cosmologies
(Elsevier B.V., 2017-01-01)
We investigate the cosmological production of gravitational waves in a nonsingular flat cosmology powered by a running vacuum energy density described by rho(Lambda) = rho(Lambda)(H), a phenomenological expression potentially ...
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, ...
Multimessenger astronomy with gravitational waves and high-energy neutrinos
(American Physical Society, 2013-10)
Many of the astrophysical sources and violent phenomena observed in our Universe are potential emitters of gravitational waves and high-energy cosmic radiation, including photons, hadrons, and presumably also neutrinos. ...
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 ...
SEARCH for MONOCHROMATIC SIGNALS USING DATA FROM the ALLEGRO GRAVITATIONAL WAVE DETECTOR
(World Scientific Publ Co Pte Ltd, 2010-08-01)
We present a data analysis method for searching monochromatic signals in temporal series. With this method it is possible to estimate the power spectrum by using averaged modified periodograms which reinforce the presence ...
Search for gravitational waves associated with gamma-ray bursts detected by the InterPlanetary Network
(2014)
We present the results of a search for gravitational waves associated with 223 γ-ray bursts (GRBs) detected by the InterPlanetary Network (IPN) in 2005-2010 during LIGO´s fifth and sixth science runs and Virgo´s first, ...
Discriminating cosmological expansion models with third generation gravitational wave detectors
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM FÍSICA, 2019-02-26)
No alvorecer da Astronomia das Ondas Gravitacionais, novos caminhos têm sido
aberto para testar e restringir modelos cosmológicos. Simulando sirenes padrões detectadas pelo detector terrestre de terceira geração de ondas ...
