Probing the structure of jet-driven core-collapse supernova and long gamma-ray burst progenitors with high-energy neutrinos

Abstract

Times of arrival of high energy neutrinos encode information about their sources. We demonstrate that the energy-dependence of the onset time of neutrino emission in advancing relativistic jets can be used to extract important information about the supernova/gamma-ray burst progenitor structure. We examine this energy and time dependence for different supernova and gamma-ray burst progenitors, including red and blue supergiants, helium cores, Wolf-Rayet stars, and chemically homogeneous stars, with a variety of masses and metallicities. For choked jets, we calculate the cutoff of observable neutrino energies depending on the radius at which the jet is stalled. Further, we exhibit how such energy and time dependence may be used to identify and differentiate between progenitors, with as few as one or two observed events, under favorable conditions.

High-energy neutrino follow-up search of gravitational wave event GW150914 with ANTARES and IceCube

“…This search window, which was used in previous GWneutrino searches, is a conservative, observation-based upper limit on the plausible emission of GWs and highenergy neutrinos in the case of GRBs, which are thought to be driven by a stellar-mass black hole-accretion disk system [35]. While the relative time of arrival of GWs and neutrinos can be informative [36][37][38], here we do not use detailed temporal information beyond the ±500 s time window.…”

TeV–PeV Neutrinos from Low-Power Gamma-Ray Burst Jets inside Stars

“…We show that nondetections by IceCube are consistent with theoretical expectations, and more favorable conditions for neutrinos are satisfied in lower-power GRBs such as UL GRBs. The CR acceleration simply assumed in many studies [15][16][17][18] may not be effective in CCSNe and classical GRBs since radiation smoothens the shock structure. Also, the low-power GRBs could significantly contribute to the extragalactic neutrino background (ENB), which consists of the sum of contributions from sources at various redshifts and may have been seen by IceCube [11].…”

“…In particular, IceCube is powerful enough to see high-energy (HE) neutrinos at 1 TeV [10] and has reported the first detections of cosmic PeV neutrinos [11]. Efficient HE neutrino production inside a star has been proposed assuming shock acceleration of cosmic rays (CRs) [12][13][14], and investigated by a lot of authors, since their detection allows us to study the GRB-CCSN connection [13,15], joint searches with GWs [16], neutrino mixing including the matter effect [17], the nature of GRB progenitors [18] and so on. However, IceCube has not detected neutrinos from GRBs, putting limits on this scenario as well as the classical prompt emission scenario [19,20].…”

GeV neutrinos from collisional heating in GRBs: Detection prospects with IceCube-DeepCore

“…Their flux and spectrum, or their absence, could establish the underlying mechanism. Beyond understanding relativistic outflows, high-energy neutrinos could also be used to probe the progenitor structure [3,4], or can be used along with other cosmic messengers, such as gravitational waves, to map interconnected processes within the progenitor (e.g., [5,6,7,8,9]). …”
