GRB 070724B: the first Gamma Ray Burst localized by SuperAGILE and its Swift X-ray Afterglow

E. Del Monte, M. Feroci, L. Pacciani +51

GRB 070724B is the first Gamma Ray Burst localized by SuperAGILE, the hard X-ray monitor aboard the AGILE satellite. The coordinates of the event were published hours aft…

Discovery of underground argon with low level of radioactive 39Ar and possible applications to WIMP dark matter detectors

C. Galbiati, R. Purtschert

We report on the first measurement of 39Ar in argon from underground natural gas reservoirs. The gas stored in the US National Helium Reserve was found to contain a low level of 39…

Complementarity of Gamma-ray and LHC Searches for Neutralino Dark Matter in the Focus Point Region

E. Moulin, A. Jacholkowska, G. Moultaka +7

We study the complementarity between the indirect detection of dark matter with gamma-rays in H.E.S.S. and the supersymmetry searches with ATLAS at the Large Hadron Collider in the…

Unveiling the nature of RX J0002+6246 with XMM-Newton

P. Esposito, A. De Luca, A. Tiengo +3

The X-ray source RX J0002+6246 was discovered close to the supernova remnant CTB1 in a ROSAT observation performed in 1992. The source phenomenology (soft spectrum, apparent lack o…

The first Suzaku observation of SGR 1806-20

P. Esposito, A. Tiengo, S. Zane +5

The soft gamma-ray repeater SGR 1806-20 has been attracting a lot of attention owing to the fact that in December 2004 it emitted the most powerful giant flare ever observed. Here…

Constraints on Large-Scale Magnetic Fields from the Auger Results

Alessandro De Angelis, Massimo Persic, Marco Roncadelli

A recent article from the Pierre Auger Collaboration links the direction of charged cosmic rays to possible extragalactic sites of emission. The correlation of the direction of suc…

Long term hard X-ray variability of the anomalous X-ray pulsar 1RXS J170849.0-400910 discovered with INTEGRAL

D. Gotz, N. Rea, G. L. Israel +6

We report on a multi-band high-energy observing campaign aimed at studying the long term spectral variability of the Anomalous X-ray Pulsar (AXP) 1RXS J170849.0-400910, one of the…

Evidence for a new light spin-zero boson from cosmological gamma-ray propagation?

Alessandro De Angelis, Marco Roncadelli, Oriana Mansutti

Recent findings by Imaging Atmospheric Cherenkov Telescopes indicate a large transparency of the Universe to gamma rays, which can be hardly explained within the current models of…

Axion-Like Particles, Cosmic Magnetic Fields and Gamma-Ray Astrophysics

Alessandro De Angelis, Oriana Mansutti, Marco Roncadelli

Axion-Like Particles (ALPs) are predicted by many extensions of the Standard Model and give rise to characteristic dimming and polarization effects in a light beam travelling in a…

First results from a Dark Matter search with liquid Argon at 87 K in the Gran Sasso Underground Laboratory

P. Benetti, R. Acciarri, F. Adamo +29

A new method of searching for dark matter in the form of weakly interacting massive particles (WIMP) has been developed with the direct detection of the low energy nuclear recoils…

Long term spectral variability in the soft gamma ray repeater SGR 1900+14

P. Esposito, S. Mereghetti, A. Tiengo +3

We present a systematic analysis of all the BeppoSAX data of SGR 1900+14. The observations spanning five years show that the source was brighter than usual on two occasions: ~20 da…
