Teaching special relativity in elementary physics or upper high school courses
Maria Grazia Blumetti, Biagio Buonaura, Giuseppe Giuliani +1
This paper aims to provide teachers with a tool to teach the essential features of special relativity, considering the students' difficulties highlighted by numerous studies. Our p…
Wide-band X-ray variability of GRS 1915+105 observed with BeppoSAX
P. Casella, M. Feroci, E. Massaro +9
The Galactic Microquasar GRS 1915+105 was observed by the Narrow Field Instruments onboard BeppoSAX in two pointings during year 2000. We present the preliminary results of wide-ba…
Fine phase resolved spectroscopy of the X-ray emission of the Crab pulsar (PSR B0531+21) observed with BeppoSAX
E. Massaro, G. Cusumano, M. Litterio +1
The Crab Nebula and the Pulsar have been pointed several times by the BeppoSAX satellite. We analysed all these observations, summed together, to study the main spectral properties…
Graviton Spectra in String Cosmology
Massimo Galluccio, Marco Litterio, Franco Occhionero
We propose to uncover the signature of a stringy era in the primordial Universe by searching for a prominent peak in the relic graviton spectrum. This feature, which in our specifi…
Anisotropic Inflation from Extra Dimensions
Marco Litterio, Leszek M. Sokołowski, Zdzisław A. Golda +2
Vacuum multidimensional cosmological models with internal spaces being compact -dimensional Lie group manifolds are considered. Products of 3-spheres and manifold (a nov…
Inflation in Multidimensional Quantum Cosmology
Enrico Carugno, Marco Litterio, Franco Occhionero +1
We extend to multidimensional cosmology Vilenkin's prescription of tunnelling from nothing for the quantum origin of the observable Universe. Our model consists of a -dimensio…
