It has been a mystery that with ten orders of magnitude difference in energy, high-energy neutrinos, ultrahigh-energy cosmic rays, and sub-TeV gamma rays all present comparable energy injection rate, hinting an unknown common origin. Here we show that black hole jets embedded in clusters of galaxies may work as sources of all three messengers. By numerically simulating the propagation of...

The Astrophysical Multimessenger Observatory Network (AMON) will perform realtime coincidence searches for multimessenger astrophysical transients from multiple high-energy observatory subthreshold data streams. The resulting coincidences will be distributed in realtime to followup observatories and other interested parties in the form of AMON alerts. In addition to realtime analyses, AMON...

The existence of a high-energy diffuse astrophysical neutrino flux has recently been confirmed by the IceCube Neutrino Observatory, but in the absence of any high-confidence counterparts the nature of the sources of these high-energy neutrinos is still unknown. Several candidate neutrino source populations, such as Gamma-ray Bursts and Blazar Flares predict a prompt gamma-ray emission along...

The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) has been recently selected by NASA for an in-depth probe mission concept study in preparation for the next decadal survey. POEMMA will combine the well-developed Orbiting Wide-field Light collectors (OWL) concept with the recently proposed CHerenkov from Astrophysical Neutrino Telescope (CHANT) concept to form a multi-messenger...

72. The Sun as a new laboratory for cosmic rays, gamma rays, neutrinos, and dark matter

The Sun must shine brightly in GeV—TeV gamma rays and neutrinos.  These particles are produced by the interactions of cosmic rays with solar matter and radiation.  Additional fluxes may be caused by the annihilation of dark matter in the solar core, perhaps with the eventual particles produced outside of the Sun through the decay of metastable mediators.  Importantly, a new generation of...
