MAGIC reveals a complex morphology within the unidentified gamma-ray source HESS J1857+026

Aims. HESS J1857+026 is an extended TeV gamma-ray source that was discovered by H. E. S. S. as part of its Galactic plane survey. Given its broadband spectral energy distribution and its spatial coincidence with the young energetic pulsar PSR J1856+0245, t ...

First characterization of the SPADnet sensor: a digital silicon photomultiplier for PET applications

Edoardo Charbon, Claudio Bruschini, Gabor Nemeth

Silicon Photomultipliers have the ability to replace photomultiplier tubes when used as light sensors in scintillation gamma-ray detectors. Their timing properties, compactness, and magnetic field compatibility make them interesting for use in Time-of-Flig ...

Definition of the radiation fields for the JET gamma-ray spectrometer diagnostics

Patrick Blanchard

The JET gamma-ray diagnostics system provides information on the behaviour of fast particles within the tokamak plasma. Information on the spatial distribution of the interacting fast particles is obtained from the gamma-ray cameras, while energy distribut ...

Introducing the CTA concept

Steve Couturier, Werner Lustermann, Christophe Bauer, Mathieu Ribordy, Francisco Sanchez, Xiaoqing Zhou, Reto Frei, Thomas Günther Bretz, Etienne Antoine Julien Moulin, Michael Werner, Bruno Garcia, Munehito Kagaya

The Cherenkov Telescope Array (CTA) is a new observatory for very high-energy (VHE) gamma rays. CTA has ambitions science goals, for which it is necessary to achieve full-sky coverage, to improve the sensitivity by about an order of magnitude, to span abou ...

The simultaneous low state spectral energy distribution of 1ES 2344+514 from radio to very high energies

Thomas Günther Bretz

Context. BL Lacertae objects are variable at all energy bands on time scales down to minutes. To construct and interpret their spectral energy distribution (SED), simultaneous broad-band observations are mandatory. Up to now, the number of objects studied ...

Time-Dependent Searches For Point Sources Of Neutrinos With The 40-String And 22-String Configurations Of Icecube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

This paper presents four searches for flaring sources of neutrinos using the IceCube neutrino telescope. For the first time, a search is performed over the entire parameter space of energy, direction, and time with sensitivity to neutrino flares lasting be ...

An absence of neutrinos associated with cosmic-ray acceleration in gamma-ray bursts

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

Very energetic astrophysical events are required to accelerate cosmic rays to above 10(18) electronvolts. GRBs (c-ray bursts) have been proposed as possible candidate sources(1-3). In the GRB 'fireball' model, cosmic-ray acceleration should be accompanied ...

Searching for soft relativistic jets in core-collapse supernovae with the IceCube optical follow-up program

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

Context. Transient neutrino sources such as gamma-ray bursts (GRBs) and supernovae (SNe) are hypothesized to emit bursts of high-energy neutrinos on a time-scale of less than or similar to 100 s. While GRB neutrinos would be produced in high relativistic j ...
