The MeV domain is one of the most underexplored windows on the Universe, mainly due to the challenging nature of the measurements. This is an energy range of transition in the Universe. Thermal sources dominate at lower energies, while non-thermal phenomena prevail at higher energies. In addition, observations at both gamma-ray and hard X-ray energies provide compelling evidence of...

PANGU (the PAir-productioN Gamma-ray Unit) is a small astrophysics mission with wide field of view optimized for spectro-imaging, timing and polarisation studies. It will map the gamma-ray sky from 10 MeV to a few GeV with unprecedented spatial resolution. This window on the Universe is unique to detect photons emitted directly by relativistic particles, via the decay of neutral pions, or the...

The observation of MeV celestial gamma rays provide us much information about various high energy phenomena. However, the sufficient observation has not yet been achieved due to the large radiation backgrounds and unclearness of Compton gamma-ray image.
To advance the MeV gamma-ray astronomy, we have developed an Electron-Tracking Compton Camera (ETCC) which consists of a gaseous Time...

Polarimetry is a powerful tool to study the emission processes involved in high energy astrophysical events such as Gamma-Ray Bursts (GRBs). Despite the wealth of information which can be extracted from polarimetry measurements few have been performed successfully thus far. POLAR is a novel space-borne Compton polarimeter foreseen to be launched in 2016 on the Chinese spacelab TG-2. The...

The GAMMA-400 is designed
to measure fluxes of gamma rays and the electron–positron cosmic-ray component possibly associated with annihilation or decay of dark matter particles; and to search for and study in detail Galactic Center, discrete and extended gamma-ray sources, to measure the energy spectra of Galactic and extragalactic diffuse gamma rays, and to study gamma-ray bursts and gamma...

The CALorimetric Electron Telescope (CALET) is a space-borne cosmic ray calorimeter system planned for installation on the JEM-EF platform on the International Space Station (ISS) in 2015. The CALET collaboration is a Japan-led team collaborating with researchers in Italy and the U.S. In addition to precise measurement of the cosmic ray electron and nuclei spectra, the CALET calorimeter...
