Abstract
In gamma-ray astrophysics there are several open issues, such as non thermal mechanisms in supernova remnants, the study of the high energy cut-offs in active galactic nuclei spectra, the detection of nuclear and annihilation lines and the polarization level of several gamma-ray emission sources. In order to allow the study these astrophysical open issues the Gamma-Ray Imager consortium is setting up a new gamma-ray space telescope mission proposal for the ESA Cosmic Vision program - missions to be launched between 2015 and 2025. Due to its novel gamma-ray focusing concept based on Lauelens technology, this will be the first space mission that will allow gamma-ray focusing in a broad energy band-pass (60 to 1000 keV). In the framework of the GRI consortium the Centro de Instrumentação of the University of Coimbra, a GRI consortium member, is developing a CdTe stack gamma-ray detector that will operate as Laue lens focal plane instrument.
