Large Scale Structure and Cosmological Waveguides
S Capozziello, G Iovane
A sort of gravitational waveguide effect in cosmology could explain some anomalous phenomena which cannot be understood by the current gravitational lensing models as the existence…
A New Approach to Quasars and Twins by Cosmological Waveguides
S. Capozziello, G. Iovane
The huge luminosity of quasars and "twin''images of them could be explained using filamentary or planar cosmological structures acting as waveguides. We describe the gravitational…
Quantum Signature of Cosmological Large Scale Structures
Salvatore Capozziello, Salvatore De Martino, Silvio De Siena +1
We demonstrate that to all large scale cosmological structures where gravitation is the only overall relevant interaction assembling the system (e.g. galaxies), there is associated…
The effective cosmological constant in higher order gravity theories
S. Capozziello, R. de Ritis, A. A. Marino
An effective time--dependent cosmological constant can be recovered for higher--order theories of gravity by extending to these ones the no--hair conjecture. The results are applie…
Scalar perturbations in deflationary cosmological models
S. Capozziello, G. Lambiase, G. Scarpetta
We consider scalar perturbations of energy--density for a class of cosmological models where an early phase of accelerated expansion evolves, without any fine--tuning for graceful…
