[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…
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…
