Non-local gravity effects in cosmological dynamics probed by IceCube/KM3NeT signals and dark matter relic abundance
Salvatore Capozziello, Gaetano Lambiase, Giuseppe Meluccio
Non-local gravity terms have a relevant role in determining the cosmological dynamics. Here we consider curvature- and torsion-based cosmological models where non-local terms can b…
The gravitational energy-momentum pseudo-tensor in non-metric gravity
Salvatore Capozziello, Maurizio Capriolo, Gaetano Lambiase
We derive the affine tensor associated with the energy and momentum densities of both gravitational and matter fields, the complex pseudo-tensor, for non-metric gravity, the…
Excess Radiation from Axion-Photon Conversion
Andrea Addazi, Salvatore Capozziello, Qingyu Gan +2
Two notable anomalies in radio observations -- the excess radiation in the Rayleigh-Jeans tail of the cosmic microwave background, revealed by ARCADE2, and the twice-deeper absorpt…
Non-locality in Quadrupolar Gravitational Radiation
Salvatore Capozziello, Maurizio Capriolo, Amodio Carleo +1
General Relativity suffers for two main problems which have not yet been overcome: it predicts spacetime singularities and cannot be formulated as a perturbative renormalizable the…
