  1. 105. Toward the Identification of the Cosmic Neutrino Origin

    Multi-Messenger
    To reveal the origin of diffuse PeV neutrinos observed in IceCube, we need to identify a single source. I discuss various possibilities in light of current and future neutrino detectors, and show that many of the proposed scenarios including dark matter models can be critically tested. A natural and intriguing possibility is that >0.1 PeV neutrinos originate from cosmic-ray reservoirs like...

  2. 74. Ultra-high-energy emission from an evolving gamma-ray burst: neutrinos, cosmic rays, and gamma rays

    Gamma-ray bursts (GRBs) are potential sources of ultra-high-energy neutrinos and, arguably, constitute the object class within which neutrino point sources may sooner be identified. For that reason, it is important to have a clear idea of what signals to expect from them. We present a model where the neutrino, gamma ray, and cosmic ray emission from the burst is made up of the superposition of...

    Primordial black holes (PBHs) are expected to explode violently during the last few seconds of their lives, producing jets of high energy particles. These particles could be detected in coincidence by several observatories with large fields of view, such as IceCube and ANTARES (neutrinos), HAWC and Fermi LAT (gamma rays) and Pierre Auger (neutrons). The short temporal structure of the...

  4. 90. AMON Searches for Jointly-Emitting Neutrino + Gamma-Ray Transients
    Azadeh Keivani (The Pennsylvania State University)

    Multi-Messenger
    We present the results of archival coincidence analyses between public neutrino data from the 40-string and 59-string configurations of IceCube (IC40 and IC59) with contemporaneous public gamma-ray data from Fermi LAT and Swift. Our analyses have the potential to discover statistically significant coincidences between high-energy neutrinos and gamma-ray signals, and hence, possible...

  5. 94. AMON: transition to real-time operations

    The Astrophysical Multimessenger Observatory Network (AMON) will link the world's leading high-energy neutrino, cosmic-ray, gamma-ray and gravitational wave observatories by performing real-time coincidence searches for multimessenger sources from observatory subthreshold data streams. The resulting coincidences will be distributed to interested parties in the form of electronic alerts for...

  6. 111. Implications of IceCube's neutrino discoveries for ultrahigh-energy cosmic rays
    Dr Matt Kistler (Stanford University)

    Multi-Messenger
    The discovery by IceCube of the first high-energy neutrinos with plausible extraterrestrial origins is likely informing us about some of the most extreme environments in the Universe. I will discuss from a theoretical perspective what this new flux has already told us about the inner workings of the sources of extragalactic cosmic rays. Additionally, I will touch upon connections with a...
