e-ASTROGAM mission: a major step forward for gamma-ray polarimetry
Laurent, Philippe; Hanlon, Lorraine; Gouiffès, Christian +5 more
e-ASTROGAM is a gamma-ray space mission proposed for the fifth medium-size mission (M5) of the European Space Agency. It is dedicated to the study of the nonthermal universe in the photon energy range from ∼0.15 MeV to 3 GeV with unprecedented sensitivity and angular and energy resolution, together with a ground-breaking capability for gamma-ray p…

Enoto, Teruaki; Yamaoka, Kazutaka; Fukazawa, Yasushi +39 more
Hitomi (ASTRO-H) was the sixth Japanese x-ray satellite that carried instruments with exquisite energy resolution of <7 eV and broad energy coverage of 0.3 to 600 keV. The Soft Gamma-ray Detector (SGD) was the Hitomi instrument that observed the highest energy band (60 to 600 keV). The SGD design achieves a low background level by combining act…
