Understanding Cygnus X-3 Through Multi-Wavelength Studies
Michael McCollough, Karri Koljonen, Diana Hannikainen +5
Cygnus X-3 is a unique microquasar which shows X-ray state changes, strong radio emission, and relativistic jets. It is also an unusual X-ray binary with the mass-donating companio…
Flux variability in the FSRQ 1510-089. A radio-gamma perspective
M. Orienti, G. Giovannini, D. Dallacasa +5
The knowledge of the physical conditions occurring in the relativistic jet of radio-loud active galactic nuclei (AGNs) is important to understand the mechanisms at the basis of the…
Gamma-Ray Localization of Terrestrial Gamma-Ray Flashes
M. Marisaldi, A. Argan, A. Trois +59
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 carr…
Agile Observations of the "Soft" Gamma-Ray Pulsar PSR B1509-58
M. Pilia, A. Pellizzoni, A. Trois +60
We present the results of new Agile observations of PSR B1509-58 performed over a period of 2.5 years following the detection obtained with a subset of the present data. The modula…
The December 2009 gamma-ray flare of 3C 454.3: the multifrequency campaign
L. Pacciani, V. Vittorini, M. Tavani +81
During the month of December, 2009 the blazar 3C 454.3 became the brightest gamma-ray source in the sky, reaching a peak flux F ~2000E-8 ph/cm2/s for E > 100 MeV. Starting in Novem…
Magic constraints on Gamma-ray emission from Cygnus X-3
J. Aleksić, L. A. Antonelli, P. Antoranz +156
Cygnus X-3 is a microquasar consisting of an accreting compact object orbiting around a Wolf-Rayet star. It has been detected at radio frequencies and up to high-energy gamma rays…
