Description
The death of massive stars is accompanied by the formation of central and accreting compact objects and the subsequent launch of relativistic jets. However, not all jets successfully drill their way out of the stellar envelope, which would result in gamma-ray emission. Unsuccessful jets, also known as choked jets, might still produce radiation at lower frequencies by dissipating the jet energy into a pressurized cocoon, which expands within the stellar envelope and eventually breaks out as a mildly relativistic outflow. In order to investigate the radiation output of choked jets, we perform radiative relativistic non-resistive MHD simulations of jets launched into collapsars and derive in post-processing analysis the secondary emission by accelerated particles at shocks, including multi-wavelength and neutrino spectra. Our results are shown for different configurations of the system.
