Correct light deflection in Weyl conformal gravity
Carlo Cattani, Massimo Scalia, Ettore Laserra +2
The conformal gravity fit to observed galactic rotation curves requires γ>0. On the other hand, conventional method for light deflection by galaxies gives a negative contribution t…
Intra--Galactic thin shell wormhole and its stability
Ivana Bochicchio, Ettore Laserra
In this paper, we construct an intra-galactic thin shell wormhole joining two copies of identical galactic space times described by the Mannheim-Kazanas de Sitter solution in confo…
The Weierstrass Criterion and the Lemaitre-Tolman-Bondi Models with Cosmological Constant λ
Ivana Bochicchio, Salvatore Capozziello, Ettore Laserra
We analyze Lemaitre-Tolman-Bondi models in presence of the cosmological constant Λthrough the classical Weierstrass criterion. Precisely, we show that the Weierstrass approach allo…
Cosmological expansion and local systems: a Lemaître-Tolman-Bondi model
Ivana Bochicchio, Valerio Faraoni
We propose a Lemaître-Tolman-Bondi system mimicking a two-body system to address the problem of the cosmological expansion versus local dynamics. This system is strongly bound but…
A Lemaitre-Tolman-Bondi cosmological wormhole
Ivana Bochicchio, Valerio Faraoni
We present a new analytical solution of the Einstein field equations describing a wormhole shell of zero thickness joining two Lemaıtre-Tolman-Bondi universes, with no radial accre…
Computational Approach to Gravitational Waves Forms in Stellar Systems as Complex Structures through Keplerian Parameters
Ivana Bochicchio, Mariafelicia De Laurentis, Ettore Laserra
In this paper we investigate the gravitational waves emission by stellar dynamical structures as complex systems in the quadrupole approximation considering bounded and unbounded o…
