Multiwavelength observations of 3C 454.3. I. The AGILE 2007 November campaign on the "Crazy Diamond"
S. Vercellone, A. W. Chen, V. Vittorini +68
[Abridged] We report on a multiwavelength observation of the blazar 3C 454.3 (which we dubbed "crazy diamond") carried out on November 2007 by means of the astrophysical satellites…
The 2008 May burst activation of SGR 1627-41
P. Esposito, G. L. Israel, S. Zane +16
In May 2008 the soft gamma-ray repeater SGR 1627-41 resumed its bursting activity after nearly a decade of quiescence. After detection of a bright burst, Swift pointed its X-ray te…
Detectability of gamma-ray emission from classical novae with Swift/BAT
F. Senziani, G. K. Skinner, P. Jean +1
Classical novae are expected to emit gamma rays during their explosions. The most important contribution to the early gamma-ray emission comes from the annihilation with electrons…
Hard X-ray emission of the microquasar GRO J1655-40 during the rise of its 2005 outburst
A. Joinet, E. Kalemci, F. Senziani
We present the analysis of the high energy emission of the Galactic black hole GRO J1655-40 at the beginning of its 2005 outburst. The data from 458 ks of INTEGRAL observations, sp…
Using GRO J1655-40 to test Swift/BAT as a monitor for bright hard X-ray sources
F. Senziani, G. Novara, A. De Luca +3
While waiting for new gamma-ray burst detections, the Burst Alert Telescope (BAT) on board Swift covers each day ~50% of the sky in the hard X-ray band (``Survey data''). The large…
A new symbiotic low mass X-ray binary system: 4U 1954+319
F. Mattana, D. Gotz, M. Falanga +4
4U 1954+319 was discovered 25 years ago, but only recently has a clear picture of its nature begun to emerge. We present for the first time a broad-band spectrum of the source and…
