First detection of Co56 gamma-ray lines from type Ia supernova (SN2014J) with INTEGRAL
Abstract
We report the first ever detection of Co56 lines at 847 and 1237 keV and a continuum in the 200-400 keV band from the Type Ia supernova SN2014J in M82 with INTEGRAL observatory. The data provide direct evidence of a thermonuclear explosion in M82, which produced about 0.6 Msun of radioactive Ni56.
