Dr Sabina Sabatini (INAF IAPS)
Gamma-ray observations by the AGILE satellite during the period mid-2007-2010 of the black hole binary system Cygnus X-1 will be presented. The source was observed both in the most common hard state and during a remarkably prolonged `soft state' phase (June 2010 -- May 2011). Previous 1--10 MeV observations of Cyg X-1 in this state hinted at a possible existence of a non-thermal particle...
Dr Giovanni Piano (INAF-IAPS Roma)
The AGILE satellite detected several episodes of transient gamma-ray emission from Cygnus X-3. Cross-correlating the AGILE light curve with both X-ray and radio monitoring data, we found that the main events of gamma-ray activity were detected while the system was in soft spectral X-ray states, that coincide with local and often sharp minima of the hard X-ray flux, a few days before intense...
Marco Giulio Giammarchi (MI)
The Borexino experiment has recently completed the Phase I and has already started the Phase II, with even lower radioactive background. The talk will summarize the result of the Phase I on solar and geophysical neutrinos. Besides, it will cover the contents of the letter of intent of Phase II, recently published on ArXiV. The Phase II aims at the completion of the study of the low energy...
Bjoern Lehnert (TU Dresden)
The GERmanium Detector Array (GERDA) is an experiment designed to investigate the neutrinoless double beta decay (0nubb) in 76Ge. An array of high purity germanium detectors enriched to 86% of 76Ge is operated inside 65m^3 of liquid argon (LAr) inside the Laboratori Nazionali del Gran Sasso. The experiment aims to explore the 0nubb half-life up to 1.4e26 yr with a collected exposure of 100 kg...
71. Cross section measurements of fusion reactions at astrophysically relevant energies: the LUNA experiment
Dr Alba Formicola (LNGS)
Accurate knowledge of thermonuclear reaction rates is important in understanding the generation of energy, the luminosity of neutrinos, and the synthesis of elements in stars. The LUNA Collaboration has shown that, by going underground and by using the typical techniques of low background physics, it is possible to measure nuclear cross sections down to the energy of the nucleosynthesis...
