Age constraints in the double pulsar system J0737-3039 [PDF]
, 2007 We investigate the age constraints that can be placed on the double pulsar
system using models for the spin-down of the first-born 22.7-ms pulsar A and
the 2.77-s pulsar B with characteristic ages of 210 and 50 Myr respectively.A. G. Lyne, A. Possenti, B. C. Joshi, D. R. Lorimer, I. H. Stairs, M. A. McLaughlin, M. Burgay, M. Kramer, N. D'Amico, P.

, 2010 Terrestrial Gamma-Ray Flashes (TGFs) are very short bursts of high energy
photons and electrons originating in Earth's atmosphere. We present here a
localization study of TGFs carried out at gamma-ray energies above 20 MeV based
on an innovative event ...Antonelli, L. A., Argan, A., Barbiellini, G., Bulgarelli, A., Caraveo, P., Cattaneo, P.

, 2011 Radio halos are extended and diffuse non-thermal radio sources present at the
cluster center, not obviously associated with any individual galaxy. A strong
correlation has been found between the cluster X-ray luminosity and the halo
radio power.Abell, Brown, Brown, Brunetti, Böhringer, Cassano, Cassano, Crawford, Ebeling, F. Govoni, Feretti, Ferrari, G.

Burst GRB 090510
, 2009 Short gamma-ray bursts (GRBs), typically lasting less than 2 s, are a special
class of GRBs of great interest. We report the detection by the AGILE satellite
of the short GRB 090510 which shows two clearly distinct emission phases: a

Renmant IC 443
, 2010 The Supernova Remnant (SNR) IC 443 is an intermediate-age remnant well known
for its radio, optical, X-ray and gamma-ray energy emissions. In this Letter we
study the gamma-ray emission above 100 MeV from IC 443 as obtained by the AGILE
satellite.Antonelli, L. A., Argan, A., Barbiellini, G., Bulgarelli, A., Caraveo, P., Cattaneo, P. W., Chen, A.
