Resumen
Core-collapse supernovae (SNe) are found in galaxies with ongoing star-formation. If a starburst galaxy hosts an active galactic nucleus (AGN) with a relativistic jet, the SN could take place inside the jet. The collision of the SN ejecta with the jet flow leads to the formation of a shock, where particles could be accelerated up to relativistic energies, and produce gamma-ray emission. In this work, we analyze the dynamical evolution of the SN within the jet, and compute the non-thermal radiation expected from the interaction. The evolution of the SN Lorentz factor and radius regulates the intensity of the non-thermal emission. The SN can achieve a relativistic regime for powerful jets, resulting in emission significantly enhanced by Doppler boosting for blazar sources. The interaction of SNe with jets of moderate luminosity can result in steady, unbeamed gamma-ray emission, that might be detectable for sources in the local universe.
