Measurements of the Soft Gamma-ray Emission from SN2014J with Suzaku
Y. Terada, K. Maeda, Y. Fukazawa +9
The hard X-ray detector (HXD) onboard {\it Suzaku} measured soft -rays from the Type Ia supernova SN2014J at days after the explosion. Although the confidence level of…
Nuclear de-excitation line spectrum of Cassiopeia A
A. Summa, D. Elsaesser, K. Mannheim
The supernova remnant Cassiopeia A is a prime candidate for accelerating cosmic ray protons and ions. Gamma rays have been observed at GeV and TeV energies, which indicates hadroni…
Nuclear lines revealing the injection of cosmic rays in supernova remnants
O. Tibolla, K. Mannheim, A. Summa +3
At high energies, the hadronic origin of gamma rays from supernova remnants is still debated. Assuming the observed gamma-rays from the Wolf-Rayet supernova remnant Cas A are due t…
Rotation-supported Neutrino-driven Supernova Explosions in Three Dimensions and the Critical Luminosity Condition
A. Summa, H. -Th. Janka, T. Melson +1
We present the first self-consistent, three-dimensional (3D) core-collapse supernova simulations performed with the Prometheus-Vertex code for a rotating progenitor star. Besides u…
Gamma-ray diagnostics of Type Ia supernovae: Predictions of observables from three-dimensional modeling
A. Summa, A. Ulyanov, M. Kromer +11
Besides the fact that the gamma-ray emission due to radioactive decays is responsible for powering the light curves of Type Ia supernovae (SNe Ia), gamma rays themselves are of par…
Gravitational waves from three-dimensional core-collapse supernova models: The impact of moderate progenitor rotation
H. Andresen, E. Müller, H. -Th. Janka +3
We present predictions for the gravitational-wave (GW) emission of three-dimensional supernova (SN) simulations performed for a 15 solar-mass progenitor with the Prometheus-Vertex…
5.9 keV Mn K-shell X-ray luminosity from the decay of 55Fe in Type Ia supernova models
I. R. Seitenzahl, A. Summa, F. Krauss +12
We show that the X-ray line flux of the Mn Kalpha line at 5.9 keV from the decay of 55Fe is a promising diagnostic to distinguish between Type Ia supernova (SN Ia) explosion models…
