We compute the fluxes of radio photons from conversion of axion-like particle dark matter in cosmic magnetic fields. We find that for axion-like particle masses around $10^{-6},$eV and effective coupling constants to photons $g_{agamma}gtrsim10^{-13},{rm GeV}^{-1}$ strongly magnetized nearby stellar winds may give detectable line-like radio photon signals, although predicted fluxes are highly uncertain due to the poorly known structure of the magnetic fields. Nevertheless, it may be worth while to conduct a dedicated search in the direction of such sources. When combined with a possible future laboratory detection of axion-like dark matter such observations may in turn provide information on the small scale magnetic field structure in such objects.

The flavor composition of high-energy astrophysical neutrinos can reveal the physics governing their production, propagation, and interaction. The IceCube Collaboration has published the first experimental determination of the ratio of the flux in ea
ch flavor to the total. We present, as a theoretical counterpart, new results for the allowed ranges of flavor ratios at Earth for arbitrary flavor ratios in the sources. Our results will allow IceCube to more quickly identify when their data imply standard physics, a general class of new physics with arbitrary (incoherent) combinations of mass eigenstates, or new physics that goes beyond that, e.g., with terms that dominate the Hamiltonian at high energy.
We propose a new strategy to search for dark matter axions using tunable cryogenic plasmas. Unlike current experiments, which repair the mismatch between axion and photon masses by breaking translational invariance (cavity and dielectric haloscopes),
a plasma haloscope enables resonant conversion by matching the axion mass to a plasma frequency. A key advantage is that the plasma frequency is unrelated to the physical size of the device, allowing large conversion volumes. We identify wire metamaterials as a promising candidate plasma, wherein the plasma frequency can be tuned by varying the interwire spacing. For realistic experimental sizes we estimate competitive sensitivity for axion masses $35-400,mu$eV, at least.
The flavor composition of high-energy astrophysical neutrinos is a rich observable. However, present analyses cannot effectively distinguish particle showers induced by $ u_e$ versus $ u_tau$. We show that this can be accomplished by measuring the in
tensities of the delayed, collective light emission from muon decays and neutron captures, which are, on average, greater for $ u_tau$ than for $ u_e$. This new technique would significantly improve tests of the nature of astrophysical sources and of neutrino properties. We discuss the promising prospects for implementing it in IceCube and other detectors.
We examine whether the newly derived neutrino spin coherence could lead to large-scale coherent neutrino-antineutrino conversion. In a linear analysis we find that such transformation is largely suppressed, but demonstrate that nonlinear feedback can
enhance it. We point out that conditions which favor this feedback may exist in core collapse supernovae and in binary neutron star mergers.
The standard perception is that the detection of high energy (TeV energies and above) neutrinos from an astrophysical object is a conclusive evidence for the presence of hadronic cosmic rays at the source. In the present work we demonstrate that TeV
neutrinos can also be originated from energetic electrons via electromagnetic interactions in different potential cosmic ray sources with flux levels comparable to that of the hadronic originated neutrinos at high energies. Our findings thus imply that at least a part of the neutrinos observed by Icecube observatory may be originated from energetic electrons. The present analysis further suggests that only a combine study of TeV gamma rays and neutrinos over a wide energy range from an astrophysical object can unambiguously identify the nature of their parents, hadrons or leptons.
