“…Alternately, in high-gradient sources (more than 1.65 keV cm −1 ), muons from pion decay will be significantly accelerated before they decay, leading to an equal flux of ν e and ν µ , and a harder neutrino spectrum [348]. In choked jets associated with supernovae and double neutron star mergers, where the neutrino production region is embedded in the progenitor star and merger ejecta respectively, the flavor ratios can further be affected by matter effects [349][350][351][352][353]. Measuring the flavor composition of high-energy neutrinos is challenging, since signals from ν e and ν τ are easy to confuse; see, however, Ref.…”

“…This will also enable investigation of particle acceleration and related plasma processes in dense environments that cannot be directly observed by electromagnetic observations, and successful detection will also be useful for probing new physics beyond the Standard Model. The candidate sources include the vicinity of supermassive black holes of AGN [334,335,553] and choked jets [340,342,343,353]. For this purpose, neutrino detectors that are sensitive to 10 TeV energies or lower are important.…”

Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy physics. With energies far beyond solar, supernovae, atmospheric, and accelerator neutrinos, high-energy and ultrahigh-energy neutrinos probe fundamental physics from the TeV scale to the EeV scale and beyond. They are sensitive to physics both within and beyond the Standard Model through their production mechanisms and in their propagation over cosmological distances. They carry unique information about their extreme non-thermal sources by giving insight into regions that are opaque to electromagnetic radiation. This white paper describes the opportunities astrophysical neutrino observations offer for astrophysics and high-energy physics, today and in coming years.Fully opening the HE and UHE neutrino windows requires a multi-pronged approach that explores a broad range of proposed experimental techniques. With upcoming neutrino telescopes, the goal is to improve the sensitivity ten-fold in the HE range and hundred-fold in the UHE range. In the HE range, we are moving into the high-statistics era, where subtle features may be resolved and multiple sources may be discovered. In the UHE range, neutrino flux predictions and physics tests are well-motivated, but we will likely need new techniques to enable discoveries. The ongoing efforts to develop new instruments will improve sensitivity, increase statistics, and expand the energy range. A broad range of experimental approaches, with complementary capabilities, must be developed and tested in the coming decades. Because it is not clear which techniques will prevail, we advocate for a broad portfolio of experiments in the HE and UHE neutrino sector. Owing to their potential, HE and UHE neutrinos should be at the forefront of the high-energy physics program, as they push the boundaries for the neutrino, cosmic, energy, theory, and instrumentation frontiers. 4 Experimental landscape 32 4.1 Overview 32 4.2 High-energy range 35 4.3 Ultra-High Energy Range (> 100-PeV) 45

“…Recent studies have indicated that some supernovae are powered by jets and/or magnetar winds, which may also be promising sources of high-energy neutrinos and UHECRs (159,160,161,162,163,164). In particular, choked jets have been suggested as the sources of the all-sky neutrino flux in the 10-100 TeV range (159,165). 5.2.3.…”

The detection of an astrophysical flux of neutrinos in the TeV-PeV energy range by the IceCube observatory has opened new possibilities for the study of extreme cosmic accelerators. The apparent isotropy of the neutrino arrival directions favors an extragalactic origin for this flux, potentially created by a large population of distant sources. Recent evidence for the detection of neutrino emission from extragalactic sources include the active galaxies TXS 0506+056 and NGC 1068. We here review the current status of the search for the sources of the high-energy neutrino flux, concentrating on its extragalactic contribution. We discuss the implications of these observations for multimessenger studies of cosmic sources and present an outlook for how additional observations by current and future instruments will help address fundamental questions in the emerging field of high-energy neutrino astronomy.

“…But the fact that it does so by imprinting the dark matter halo profile in the energy dependence of neutrino flavour ratios is rather intriguing. Alternatively, such an energy dependence might even originate at the source [10,11] Various implications of the measurement of neutrino flavour ratios at IceCube have been studied in the literature, such as constraining certain new physics scenarios [12][13][14][15], neutrino decay [16][17][18][19][20], testing the unitarity of mixing matrix [21], contributions from exotic sources [22,23], various neutrino-DM interactions [9,24,25], etc.…”

High energy astrophysical neutrinos interacting with ultralight dark matter (DM) can undergo flavour oscillations that induce an energy dependence in the flavour ratios. Such a dependence on the neutrino energy will reflect in the track to shower ratio in neutrino telescopes like IceCube or KM3NeT. This opens up a possibility to study DM density profiles of astrophysical objects like AGN, GRB etc., which are the suspected sources of such neutrinos.
