Description
Core-collapse supernovae (CCSNe) are promising multi-messenger sources, potentially emitting neutrinos and electromagnetic radiation across a wide range of timescales and energies. For very extended stellar envelopes, relativistic jets launched in the explosion may fail to escape the progenitor star, forming so-called choked jets. While these systems are invisible in gamma rays, they can be sites of particle acceleration and may contribute to the diffuse high-energy neutrino flux observed by IceCube. They can also produce early ultraviolet and optical emission through jet–ejecta and circumstellar interactions, offering complementary probes of the early explosion dynamics.
In this talk, I will present a multi-messenger perspective on CCSNe focused on these hidden jet-driven events, and discuss how neutrinos and early electromagnetic signals can be combined to uncover otherwise obscured explosions. I will outline observational strategies that connect wide-field transient surveys with neutrino detectors. I will also highlight recent progress in the theoretical and numerical modeling of these systems. These efforts aim to assess whether choked jets are efficient sites of particle acceleration and to derive more robust predictions for their electromagnetic signatures in these stellar environments.
