    • Early 56Ni decay gamma rays from SN2014J suggest an unusual explosion 

      Diehl, R.; Siegert, T.; Hillebrandt, W.; Grebenev, S.~A.; Greiner, J.; Krause, M.; Kromer, M.; Maeda, K.; Röpke, F.; Taubenberger, S. (2014-09-05)
      Type Ia supernovae result from binary systems that include a carbon-oxygen white dwarf, and these thermonuclear explosions typically produce 0.5 solar mass of radioactive 56Ni. The 56Ni is commonly believed to be buried ...

    • SN2014J gamma rays from the $^56$Ni decay chain 

      Diehl, R.; Siegert, T.; Hillebrandt, W.; Krause, M.; Greiner, J.; Maeda, K.; Röpke, F.~K.; Sim, S.~A.; Wang, Wei; Zhang, X. (2015-02-01)
      Context. The detection and measurement of gamma-ray lines from the decay chain of 56Ni provides unique information about the explosion in supernovae. SN2014J at 3.3 Mpc is a sufficiently-nearby supernova of type Ia so that ...
