Even though the gamma-ray emission due to radioactive decays is responsible for powering the light curves of SNe Ia, gamma rays themselves are of particular interest as a diagnostic tool because they directly lead to deeper insight into the nucleosynthesis and the kinematics of these explosion events.application/pdfKeywords: Gamma rays: generals; Gamma-ray diagnostics; Line: formation; Nuclear reactions , nucleosynthesis , abundances; Radiative transfer simulations; Space observatories; Supernovae: general; Three-dimensional modeling; Chemical elements; Explosions; Gamma rays Gamma rays: general; Hydrodynamics; Line: formation; Nuclear reactions, nucleosynthesis, abundances; Radiative transfer; Supernovae: general201310.1051/0004-6361/2012209722018-11-29
