| contents | Choked jets (CJ) have attracted particular attention as potential sources of high-energy cosmic neutrinos. Testing this hypothesis is challenging because of the missing gamma-ray counterpart, hence the identification of other electromagnetic (EM) signatures is crucial. A CJ source is expected harbouring in core-collapse supernovae (CCSNe) with extended H envelopes, releasing ultraviolet (UV) and optical emission for a few days. The UV band will be visible with an unprecedentedly large field of view by the future satellite ULTRASAT, for which we investigate the detection prospects in relation to the CJ visibility in the optical band with the currently operating telescope ZTF. ULTRASAT will be able to double the volume of sky currently visible by ZTF for the same emitting sources (sample of observed Type II SNe enlarged by 50%). As these sources can produce neutrinos via hadronic/photohadronic interactions in CJ, we investigate how neutrino observations by existing Cherenkov high-energy neutrino telescopes (IceCube and KM3NeT) can be used in association with EM signals coming from shock breakout (SBO) events. For optimized multimessenger detections, the delay between neutrino produced at SBO (during the jet propagation inside the stellar envelope) and ULTRASAT observations should be of around 4(5) days, with a follow-up by instruments like ZTF about one week after. We estimate that at most ~20% of the CCSNe from red supergiant stars detectable with ULTRASAT might host a CJ and release TeV neutrinos. EM and neutrino detections, if accompanied by photometric and spectroscopic follow-up with evidence for a relativistic jet launched by the central engine, would suggest CCSNe harbouring choked jets as main contributors to the cosmic diffuse neutrino flux. |
