Gravitational wave burst search in the Virgo C7 data
The Virgo Collaboration, F. Acernese
A search for gravitational wave burst events has been performed with the Virgo C7 commissioning run data that have been acquired in September 2005 over five days. It focused on un-…
Arithmetical Chaos and Quantum Cosmology
Luca Antonio Forte
In this note, we present the formalism to start a quantum analysis for the recent billiard representation introduced by Damour, Henneaux and Nicolai in the study of the cosmologica…
Relativistic orbits with gravitomagnetic corrections
S. Capozziello, M. De Laurentis, F. Garufi +1
Corrections to the relativistic orbits are studied considering higher order approximations induced by gravitomagnetic effects. We discuss in details how such corrections come out t…
Exact -cosmological model coming from the request of the existence of a Noether symmetry
S. Capozziello, P. Martin-Moruno, C. Rubano
We present an -cosmological model with an exact analytic solution, coming from the request of the existence of a Noether symmetry, which is able to describe a dust-dominated…
Solution of Maxwell's equations on a de Sitter background
Donato Bini, Giampiero Esposito, Roberto Valentino Montaquila
The Maxwell equations for the electromagnetic potential, supplemented by the Lorenz gauge condition, are decoupled and solved exactly in de Sitter space-time studied in static sphe…
Position and frequency shifts induced by massive modes of the gravitational wave background in alternative gravity
S. Bellucci, S. Capozziello, M. De Laurentis +1
Alternative theories of gravity predict the presence of massive scalar, vector, and tensor gravitational wave modes in addition to the standard massless spin~2 graviton of general…
A scaling law for the cosmological constant from a stochastic model for cosmic structures
S. Capozziello, S. Funkhouser
A set of scaling laws, based on the stochastic motions of the granular components of astronomical systems, is applied to a cosmological model with a positive cosmological constant.…
Scalar-tensor cosmology with R^{-1} curvature correction by Noether Symmetry
H. Motavali, S. Capozziello, M. Rowshan Almeh Jog
We discuss scalar-tensor cosmology with an extra correction by the Noether Symmetry Approach. The existence of such a symmetry selects the forms of the coupling , of…
Optical caustics of Kerr spacetime: the full structure
V. Bozza
We present an exhaustive numerical investigation of the optical caustics in gravitational lensing by a spinning black hole for an observer at infinity. Besides the primary caustic,…
From Dark Energy and Dark Matter to Dark Metric
S. Capozziello, M. De Laurentis, M. Francaviglia +1
It is nowadays clear that General Relativity cannot be the definitive theory of Gravitation due to several shortcomings that come out both from theoretical and experimental viewpoi…
Averaging procedure in variable-G cosmologies
Vincenzo F. Cardone, Giampiero Esposito
Previous work in the literature had built a formalism for spatially averaged equations for the scale factor, giving rise to an averaged Raychaudhuri equation and averaged Hamiltoni…
Gravitational waves about curved backgrounds: a consistency analysis in de Sitter spacetime
Donato Bini, Salvatore Capozziello, Giampiero Esposito
Gravitational waves are considered as metric perturbations about a curved background metric, rather than the flat Minkowski metric since several situations of physical interest can…
f(R) cosmology by Noether's symmetry
Salvatore Capozziello, Antonio De Felice
A general approach to find out exact cosmological solutions in f(R)-gravity is discussed. Instead of taking into account phenomenological models, we assume, as a physical criterium…
Search for gravitational waves associated with GRB 050915a using the Virgo detector
The Virgo collaboration
In the framework of the expected association between gamma-ray bursts and gravitational waves, we present results of an analysis aimed to search for a burst of gravitational waves…
A Cross-correlation method to search for gravitational wave bursts with AURIGA and Virgo
AURIGA Collaboration, Virgo Collaboration
We present a method to search for transient GWs using a network of detectors with different spectral and directional sensitivities: the interferometer Virgo and the bar detector AU…
Gravitational waves from hyperbolic encounters
S. Capozziello, M. De Laurentis, F. De Paolis +2
The emission of gravitational waves from a system of massive objects interacting on hyperbolic orbits is studied in the quadrupole approximation. Analytic expressions are derived f…
f(R) gravity with torsion: a geometric approach within the J-bundles framework
S. Capozziello, R. Cianci, C. Stornaiolo +1
We discuss the f(R)-theories of gravity with torsion in the framework of jet-bundles. Such an approach is particularly useful since the components of the torsion and curvature tens…
