| Abstract: | The article discusses the detection of gamma rays from radioactive nickel isotope 56 (56Ni) produced by the thermonuclear explosion of the type-Ia supernova SN2014J in the starburst galaxy M82. Topics include uncertainty about the physics that drives the explosion of type-Ia supernovae, an analysis of data from the Spectrometer (SPI) on the International Gamma Ray Astrophysics Laboratory (INTEGRAL) space mission, and the role of carbon-oxygen white dwarfs in supernova events. |
