The impact of gravitational lensing in the reconstruction of stellar orbits around Sgr A*
Silvia Pietroni, Valerio Bozza
After the amazing discoveries by the GRAVITY collaboration in the last few years on the star S2 orbiting the black hole Sgr A* in the center of the Milky Way, we present a detailed…
Solstices and Equinoxes in 1703 at the meridian line of St. Maria degli Angeli in Rome, and the stellar aberration of Sirius
Costantino Sigismondi, Silvia Pietroni
The 1703 was the first year of full operation of the meridian line in the Basilica of St. Maria degli Angeli in Rome. The instants of solstices and equinoxes, the \textit{Anni Card…
Astrophysical sources and acceleration mechanisms
Martina Adamo, Silvia Pietroni, Maurizio Spurio
Multi-messenger astronomy provides for the observation of the same astronomical event with different kind of telescopes at the same time: optical observations, X-rays, gamma-ray bu…
Einstein, Planck and Vera Rubin: relevant encounters between the Cosmological and the Quantum Worlds
Paolo Salucci, Giampiero Esposito, Gaetano Lambiase +38
In Cosmology and in Fundamental Physics there is a crucial question like: where the elusive substance that we call Dark Matter is hidden in the Universe and what is it made of?, th…
Caustics in gravitational lensing by mixed binary systems
Valerio Bozza, Silvia Pietroni, Chiara Melchiorre
We investigate binary lenses with potentials in the asymmetric case with two lenses with different indexes and . These kinds of potentials have been widely used in s…
Solar neutrino flare, megaton neutrino detectors and human space journey
Daniele Fargion, Pietro Oliva, P. G. De Sanctis Lucentini +5
The largest solar flare have been recorded in gamma flash and hard spectra up to tens GeV energy. The present building and upgrade of Hyper- Kamiokande (HK) in Japan and Korea, (as…
