Power for dry BL Lacertae objects
A. Paggi, A. Cavaliere, V. Vittorini +1
Is it significant that the intrinsic outputs of several BL Lacs are observed to level off at values of about 10^46 erg s^-1? In searching for an answer, we compare gamma-ray observ…

Technical aspects and dark matter searches
R. Bernabei, P. Belli, F. Cappella +12
A variety of detectors has been proposed for dark matter direct detection, but most of them -- by the fact -- are still at R&D stage. In many cases, it is claimed that the lack of…

We report the first detection of very-high-energy (VHE) gamma-ray emission above 140 GeV from PKS 1424+240, a BL Lac object with an unknown redshift. The photon spectrum above 140…
Discovery of extreme particle acceleration in the microquasar Cygnus X-3
M. Tavani, A. Bulgarelli, G. Piano +67
The study of relativistic particle acceleration is a major topic of high-energy astrophysics. It is well known that massive black holes in active galaxies can release a substantial…
