A Neutral Beam Model for High-Energy Neutrino Emission from the Blazar TXS 0506+056
B. Theodore Zhang, Maria Petropoulou, Kohta Murase +1
The IceCube collaboration reported a excess of neutrino events in the direction of the blazar TXS 0506+56 during a 6 month period in 2014-2015, as well a…
The POEMMA (Probe of Extreme Multi-Messenger Astrophysics) mission
A. V. Olinto, J. H. Adams, R. Aloisio +42
The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to observe cosmic neutrinos (CNs) above 20 PeV and ultra-high energy cosmic rays (UHECRs) above 20 EeV over t…
A two-zone model for blazar emission: implications for TXS 0506+056 and the neutrino event IceCube-170922A
Rui Xue, Ruo-Yu Liu, Maria Petropoulou +4
A high-energy muon neutrino event, IceCube-170922A, was recently discovered in both spatial and temporal coincidence with a gamma-ray flare of the blazar TXS 0506+056. It has been…
POEMMA (Probe of Extreme Multi-Messenger Astrophysics) design
A. V. Olinto, J. H. Adams, R. Aloisio +42
The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is a NASA Astrophysics probe-class mission designed to observe ultra-high energy cosmic rays (UHECRs) and cosmic neutrino…
On the radiation energy density in the jet of high-energy emitting BL Lac objects and its impact on their multi-messenger role
F. Tavecchio, F. Oikonomou, C. Righi
We examine the potential multi-messenger role of BL Lac objects emitting at high energy (so-called HBL) focusing on the limits on the energy density of soft radiation in the jet fr…
All-sky Medium Energy Gamma-ray Observatory: Exploring the Extreme Multimessenger Universe
Julie McEnery, Juan Abel Barrio, Ivan Agudo +182
The All-sky Medium Energy Gamma-ray Observatory (AMEGO) is a probe class mission concept that will provide essential contributions to multimessenger astrophysics in the late 2020s…
High energy neutrino flux from individual blazar flares
Foteini Oikonomou, Kohta Murase, Paolo Padovani +2
Motivated by the recently reported evidence of an association between a high-energy neutrino and a gamma-ray flare from the blazar TXS 0506+056, we calculate the expected high-ener…
Measurement of the Crab Nebula Spectrum Past 100 TeV with HAWC
HAWC Collaboration, A. U. Abeysekara, A. Albert +102
We present TeV gamma-ray observations of the Crab Nebula, the standard reference source in ground-based gamma-ray astronomy, using data from the High Altitude Water Cherenkov (HAWC…
Open Questions in Cosmic-Ray Research at Ultrahigh Energies
Rafael Alves Batista, Jonathan Biteau, Mauricio Bustamante +13
We review open questions and prospects for progress in ultrahigh-energy cosmic ray (UHECR) research, based on a series of discussions that took place during the `The High-Energy Un…
High-Energy Neutrinos from Blazar Flares and Implications of TXS 0506+056
Foteini Oikonomou, Kohta Murase, Maria Petropoulou
Motivated by the observation of a TeV muon neutrino by IceCube, coincident with a 6 month-long -ray flare of the blazar TXS 0506+056, and an archival search which r…
The Astrophysical Multimessenger Observatory Network (AMON): Performance and Science Program
Hugo A. Ayala Solares, Stephane Coutu, D. F. Cowen +9
The Astrophysical Multimessenger Observatory Network (AMON) has been built with the purpose of enabling near real-time coincidence searches using data from leading multimessenger o…
TXS 0506+056, the first cosmic neutrino source, is not a BL Lac
P. Padovani, F. Oikonomou, M. Petropoulou +2
We present evidence that TXS 0506+056, the first plausible non-stellar neutrino source, despite appearances, is not a blazar of the BL Lac type but is instead a masquerading BL Lac…
