The annihilation of dark matter into neutrinos over a range of dark matter masses from MeV/c
2 to ZeV/c 2 is reviewed. Thermally produced models of dark matter are expected to self …

The observation of electromagnetic radiation from radio to γ-ray wavelengths has provided a
wealth of information about the Universe. However, at PeV (10 15 eV) energies and above …

Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy
physics. With energies far beyond solar, supernovae, atmospheric, and accelerator …

New light states thermally coupled to the Standard Model plasma alter the expansion history
of the Universe and impact the synthesis of the primordial light elements. In this work, we …

Neutrinos are one of the most promising messengers for signals of new physics Beyond the
Standard Model (BSM). On the theoretical side, their elusive nature, combined with their …

Optical frequency metrology in atoms and ions can probe hypothetical fifth forces between
electrons and neutrons by sensing minute perturbations of the electronic wave function …

It is possible that the strongest interactions between dark matter and the Standard Model
occur via the neutrino sector. Unlike gamma rays and charged particles, neutrinos provide a …

The flux of high energy neutrinos and photons produced in a blazar could get attenuated
when they propagate through the dark matter spike around the central black hole and the …

Despite numerous dedicated experimental searches, the elusive nature of dark matter [1]
remains one of the most important problems in modern physics. High-energy neutrinos …

Recent observations of high-energy neutrinos from active galactic nuclei (AGN), NGC 1068
and TXS 0506+ 056, suggest that cosmic rays (CRs) are accelerated in the vicinity of the …
