Constraining high-energy neutrino emission from choked jets in stripped-envelope supernovae

Abstract

There are indications that γ-ray dark objects such as supernovae (SNe) with choked jets, and the cores of active galactic nuclei may contribute to the diffuse flux of astrophysical neutrinos measured by the IceCube observatory. In particular, stripped-envelope SNe have received much attention since they are capable of producing relativistic jets and could explain the diversity in observations of collapsar explosions (e.g., gamma-ray bursts (GRBs), low-luminosity GRBs, and Type Ibc SNe). We use an unbinned maximum likelihood method to search for spatial and temporal coincidences between Type Ibc core-collapse

Host Galaxies of Type Ic and Broad-lined Type Ic Supernovae from the Palomar Transient Factory: Implications for Jet Production

“…3) An engine is present, but the jet did not punch through the stellar envelope as it was too low in energy, was choked or did not last long enough (Milisavljevic et al 2015;Modjaz et al 2016). Understanding which CC-SNe harbor choked jets would also impact identifying the astrophysical sources for the diffuse flux of high-energy Icecube neutrino (Senno et al 2018).…”

Data-driven Detection of Multimessenger Transients

“…While the exact nature of the emission remains elusive, its apparent isotropy suggests that it originates from relatively weak extragalactic sources. Possible sources of ultra high-energy cosmic rays (UHECRs) and neutrinos include long-and short-duration gamma-ray bursts (GRBs), as well as core-collapse supernovae (CC-SNe) with choked jets or shock breakouts (Kashiyama et al 2013;Senno et al 2018). The energy density of the astrophysical neutrinos is comparable to that of the isotropic γ-ray background and to that of UHE-CRs (Meszaros et al 2019).…”

“…This motivates performing a stacking analysis, combining observations from many events. We simulate a neutrino stacking analysis, intended to identify an accumulated neutrino over-density in spatiotemporal coincidence with CC-SNe (Senno et al 2018). This should be distinguished from the more direct crosscorrelation approach, which involves optical follow-up of specific neutrino events (Morgan 2019).…”

High-Energy Multimessenger Transient Astrophysics

“…The nondetection of coincident events between neutrinos and GRBs has led to important constraints on cosmic-ray acceleration in GRBs (44,45). Stacking searches for neutrino-supernova associations have also been performed (46,47). Multiplet searches are also powerful for the transient neutrino sources (48,49).…”
