Extreme learning machine collocation for the numerical solution of elliptic PDEs with sharp gradients
Francesco Calabrò, Gianluca Fabiani, Constantinos Siettos
We introduce a new numerical method based on machine learning to approximate the solution of elliptic partial differential equations with collocation using a set of sigmoidal funct…
Non-Local Curvature and Gauss-Bonnet Cosmologies by Noether Symmetries
Francesco Bajardi, Salvatore Capozziello, Daniele Vernieri
Non-local gravity cosmologies are considered under the standard of Noether Symmetry Approach. In particular, we focus on non-local theories whose gravitational actions depend on cu…
Primordial Deuterium after LUNA: concordances and error budget
Ofelia Pisanti, Gianpiero Mangano, Gennaro Miele +1
The accurate evaluation of the nuclear reaction rates and corresponding uncertainties is an essential requisite for a precise determination of light nuclide primordial abundances.…
The X-ray fundamental plane of the Platinum Sample, the Kilonovae and the SNe Ib/c associated with GRBs
Maria Giovanna Dainotti, Aleksander Lenart, Giuseppe Sarracino +3
A large fraction of Gamma-Ray Bursts (GRBs) lightcurves (LCs) shows X-ray plateaus. We analyze all GRBs with known redshifts presenting plateaus observed by \emph{The Neil Gehrels…
The generally covariant meaning of space distances
Salvatore Capozziello, Alice Chiappini, Lorenzo Fatibene +1
We propose a covariant and geometric framework to introduce space distances as they are used by astronomers. In particular, we extend the definition of space distances from the one…
Bouncing Cosmology in f(Q) Symmetric Teleparallel Gravity
Francesco Bajardi, Daniele Vernieri, Salvatore Capozziello
We consider f(Q) extended symmetric teleparallel cosmologies, where Q is the non-metricity scalar, and constrain its functional form through the order reduction method. By using th…
Starburst galaxies strike back: a multi-messenger analysis with Fermi-LAT and IceCube data
Antonio Ambrosone, Marco Chianese, Damiano F. G. Fiorillo +3
Starburst galaxies, which are known as "reservoirs" of high-energy cosmic-rays, can represent an important high-energy neutrino "factory" contributing to the diffuse neutrino flux…
Quasars as standard candles III. Validation of a new sample for cosmological studies
E. Lusso, G. Risaliti, E. Nardini +15
We present a new catalogue of ~2,400 optically selected quasars with spectroscopic redshifts and X-ray observations from either Chandra or XMM-Newton. The sample can be used to inv…
Brane inflation and the robustness of the Starobinsky inflationary model
S. Santos da Costa, M. Benetti, R. M. P. Neves +3
The first inflationary model conceived was the one proposed by Starobinsky which includes an additional term quadratic in the Ricci-scalar R in the Einstein-Hilbert action. The mod…
