A model-independent tripartite test of cosmic distance relations
Isabela Matos, Miguel Quartin, Luca Amendola +2
Cosmological distances are fundamental observables in cosmology. The luminosity (), angular diameter () and gravitational wave () distances are all trivially…
Gravitational wave stochastic background in reduced Horndeski theories
João C. Lobato, Isabela S. Matos, Maurício O. Calvão +1
We generalize to reduced Horndeski theories of gravity, where gravitational waves (GWs) travel at the speed of light, the expression of a statistically homogeneous and unpolarized…
Testing gravity with gravitational wave friction and gravitational slip
Isabela S. Matos, Emilio Bellini, Maurício O. Calvão +1
Gravitational waves (GWs) emitted by binary sources are interesting signals for testing gravity on cosmological scales since they allow measurements of the luminosity distance. Whe…
Constraining modified gravity with gravitational wave distance measurements
Isabela S. Matos
It has been shown in the literature that detections of gravitational waves (GWs) emitted by binary sources can provide measurements of luminosity distance. The events followed by e…
New dynamical system approach to Palatini theories and its application to exponential gravity
João C. Lobato, Isabela S. Matos, Maurício O. Calvão +1
The approach of dynamical systems is a useful tool to investigate the cosmological history that follows from modified theories of gravity. It provides qualitative information on th…
Influence of gravitational waves upon light in the Minkowski background: from null geodesics to interferometry
João C. Lobato, Isabela S. Matos, Lucas T. Santana +2
We have recently derived a manifestly covariant evolution law, under the geometrical optics approximation of the vacuum Maxwell's equations, for the electric field along null geode…
Gravitational wave propagation in models: New parametrizations and observational constraints
Isabela S. Matos, Maurício O. Calvão, Ioav Waga
Modified gravity (MG) theories predict, in general, that the ratio of gravitational wave (GW) to electromagnetic (EM) luminosity distances, , differs from its general relativity…
Influence of gravitational waves upon light. Part II. Electric field propagation and interference pattern in a gravitational wave detector
João C. Lobato, Isabela S. Matos, Lucas T. Santana +2
In this second article of the series, we apply our recently derived equation for the electric field propagation along light rays [arXiv:2004.03496], valid on the electromagnetic ge…
Influence of gravitational waves upon light. Part I. Null geodesics, radar distance and frequency shift
João C. Lobato, Isabela S. Matos, Lucas T. Santana +2
We explore different facets of the action of linearized gravitational waves in Minkowski spacetime background upon light, under the electromagnetic geometrical optics limit, coveri…
Evolution of the electric field along null rays for arbitrary observers and spacetimes
Lucas T. Santana, João C. Lobato, Isabela S. Matos +2
We derive, in a manifestly covariant and electromagnetic gauge independent way, the evolution law of the electric field , relative to an arbitrary set of inst…
