Deformations of spacetime metrics
D. Pugliese, C. Stornaiolo, S. Capozziello
This work is devoted to study the deformation of spacetime metrics as generalized conformal transformations. Some applications are also considered, in particular the equations of m…
Testing Dark Energy models vs CDM Cosmology by Supernovae and Gamma Ray Bursts
L. Izzo, S. Capozziello, G. Covone +1
A new method to constrain the cosmological equation of state is proposed by using combined samples of gamma-ray bursts (GRBs) and supernovae (SNeIa). The Chevallier-Polarski-Linder…
Stochastic Background of Relic Scalar Gravitational Waves tuned by Extended Gravity
Mariafelicia De Laurentis, Salvatore Capozziello
A stochastic background of relic gravitational waves is achieved by the so called adiabatically-amplified zero-point fluctuations process derived from early inflation. It provides…
Cosmography by GRBs : Gamma Ray Bursts as possible distance indicators
S. Capozziello, L. Izzo
A new method to constrain the cosmological equation of state is proposed by using combined samples of gamma-ray bursts (GRBs) and supernovae (SNeIa). The Chevallier-Polarski-Linder…
Fractal large-scale structure from a stochastic scaling law model
S. Capozziello, S. Funkhouser
A stochastic model relating the parameters of astrophysical structures to the parameters of their granular components is applied to the formation of hierarchical, large-scale struc…
Classifying and avoiding singularities in the alternative gravity dark energy models
S. Capozziello, M. De Laurentis, S. Nojiri +1
The future finite-time singularities emerging in alternative gravity dark energy models are classified and studied in Jordan and Einstein frames. It is shown that such singularity…
