Light scattering by radiation fields: the optical medium analogy
Donato Bini, Pierluigi Fortini, Andrea Geralico +2
The optical medium analogy of a radiation field generated by either an exact gravitational plane wave or an exact electromagnetic wave in the framework of general relativity is dev…
IGEC2: A 17-month search for gravitational wave bursts in 2005-2007
P. Astone, L. Baggio, M. Bassan +50
We present here the results of a 515 days long run of the IGEC2 observatory, consisting of the four resonant mass detectors ALLEGRO, AURIGA, EXPLORER and NAUTILUS. The reported res…
Dixon's extended bodies and impulsive gravitational waves
Donato Bini, Pierluigi Fortini, Andrea Geralico +1
The "reaction" of an extended body to the passage of an exact plane gravitational wave is discussed following Dixon's model. The analysis performed shows several general features,…
Quadrupole effects on the motion of extended bodies in Kerr spacetime
Donato Bini, Pierluigi Fortini, Andrea Geralico +1
The motion of a body endowed with dipolar as well as quadrupolar structure is investigated in the Kerr background according to the Dixon's model, extending a previous analysis done…
Quadrupole effects on the motion of extended bodies in Schwarzschild spacetime
Donato Bini, Pierluigi Fortini, Andrea Geralico +1
The motion of an extended body up to the quadrupolar structure is studied in the Schwarzschild background following Dixon's model and within certain restrictions (constant frame co…
First joint Gravitational Waves search by the Auriga-Explorer-Nautilus-Virgo collaboration
Virgo collaboration
We present results of the search for coincident burst excitations over a 24 hours long data set collected by AURIGA, EXPLORER, NAUTILUS and Virgo detectors during September 2005. T…
Correlation between Gamma-Ray bursts and Gravitational Waves
P. Tricarico, A. Ortolan, A. Solaroli +11
The cosmological origin of -ray bursts (GRBs) is now commonly accepted and, according to several models for the central engine, GRB sources should also emit at the same time gra…
Limiting sensitivity of superconductive LC - circuit placed in weak gravitational wave
P. Fortini, G. N. Izmailov
It is demonstrated that the sensitivity of a superconductive LC - circuit placed in a weak gravitational wave is limited by two factors. One is the quantization of the magnetic flu…
Gravitational Radiation from Triple Star Systems
Enrico Montanari, Mirco Calura, Pierluigi Fortini
We have studied the main features of the gravitational radiation generated by an astrophysical system constituted of three compact objects attracting one another (only via gravitat…
Gravitational Wave Interaction with Normal and Superconducting Circuits
Pierluigi Fortini, Enrico Montanari, Antonello Ortolan +1
The interaction, in the long--wavelength approximation, of normal and superconducting electromagnetic circuits with gravitational waves is investigated. We show that such interacti…
Lagrangian planetary equations in Schwarzschild space--time
Mirco Calura, Enrico Montanari, Pierluigi Fortini
We have developed a method to study the effects of a perturbation to the motion of a test point--like object in a Schwarzschild spacetime. Such a method is the extension of the Lag…
Stochastic gravitational background from inflationary phase transitions
Carlo Baccigalupi, Luca Amendola, Pierluigi Fortini +1
We consider true vacuum bubbles generated in a first order phase transition occurring during the slow rolling era of a two field inflation: it is known that gravitational waves are…
Post-Newtonian Lagrangian planetary equations
Mirco Calura, Pierluigi Fortini, Enrico Montanari
We present a method to study the time variation of the orbital parameters of a Post-Keplerian binary system undergoing a generic external perturbation. The method is the relativist…
Coherent interaction of a monochromatic gravitational wave with both elastic bodies and electromagnetic circuits
Enrico Montanari, Pierluigi Fortini
The interaction of a gravitational wave with a system made of an RLC circuit forming one end of a mechanical harmonic oscillator is investigated. We show that, in some configuratio…
