eASTROGAM

e-ASTROGAM (enhanced ASTROGAM) is a breakthrough observatory space mission proposal to ESA M5 (medium-size) call, with a detector composed by a Silicon tracker, a calorimeter, and an anticoincidence system, dedicated to the study of the non-thermal Universe in the photon energy range from 0.3 MeV to 3 GeV. The mission is based on an advanced space-proven detector technology, with unprecedented sensitivity, angular and energy resolution, combined with polarimetry capability.

The e-ASTROGAM instrumentation is optimized for the simultaneous detection of Compton and pair-producing gamma-ray events over a large spectral band. It is based on a very high technology readiness level for all subsystems and includes many innovative features for the detectors and associated electronics. Thanks to its performance in the MeV-GeV domain, substantially improving its predecessors, e-ASTROGAM will open a new window on the non-thermal Universe, making pioneering observations of the most powerful Galactic and extragalactic sources, elucidating the nature of their relativistic outflows and their effects on the surroundings. With line sensitivity in the MeV energy range one to two orders of magnitude better than previous generation instruments, e-ASTROGAM will determine the origin of key isotopes fundamental for the understanding of supernova explosions and the chemical evolution of our Galaxy.

e-ASTROGAM will be ideal for the study of high-energy sources in general, including pulsars and pulsar wind nebulae, accreting neutron stars and black holes, novae, supernova remnants and magnetars. The mission will provide unique data of significant interest to a broad astronomical community, complementary to other powerful observatories.

Aim of our participation

The Institute of Space Sciences is interested in the development, testing and calibration of the Si-strip detectors of the eASTROGAM tracker, in addition to simulations of the performance of the whole Compton-Pair instrument. Si-strip detectors will be manufactured at the IMB-CNM (CSIC) and are similar to the CdTe detectors being developed and tested in the Radiation Laboratory. ICE is member of the eASTROGAM consortium and the representative of the Spanish contribution in the mission.
