Fermi-LAT Observations of the Gamma-ray Burst GRB 130427A

LAT collaboration, GBM collaboration

The observations of the exceptionally bright gamma-ray burst (GRB) 130427A by the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope provide constraints on the nature…

The First Pulse of the Extremely Bright GRB 130427A: A Test Lab for Synchrotron Shocks

R. Preece, J. Michael Burgess, A. von Kienlin +156

Gamma-ray burst (GRB) 130427A is one of the most energetic GRBs ever observed. The initial pulse up to 2.5 s is possibly the brightest well-isolated pulse observed to date. A fine…

PAMELA and AMS-02 positron and electron spectra are reproduced by three-dimensional cosmic-ray modeling

Daniele Gaggero, Dario Grasso, Luca Maccione +2

The PAMELA collaboration recently released the absolute spectrum between 1 and 300 GeV in addition to the positron fraction and the spectrum previously measured in the…

MAGIC observations and multifrequency properties of the Flat Spectrum Radio Quasar 3C 279 in 2011

J. Aleksić, S. Ansoldi, L. A. Antonelli +168

We study the multifrequency emission and spectral properties of the quasar 3C 279. We observed 3C 279 in very high energy (VHE, E>100GeV) gamma rays, with the MAGIC telescopes duri…

The TeV blazar Markarian 421 at the highest spatial resolution

M. G. Blasi, R. Lico, M. Giroletti +14

We report the results obtained for the AGN Markarian 421 by model-fitting the data in the visibility plane, studing the proper motion of jet components, the light curve, and the sp…

First Results from NuSTAR Observations of Mkn 421

M. Baloković, M. Ajello, R. D. Blandford +34

Mkn 421 is a nearby active galactic nucleus dominated at all wavelengths by a very broad non-thermal continuum thought to arise from a relativistic jet seen at a small angle to the…
