Comprehensive Multimessenger Modeling of the Extreme Blazar 3HSP J095507.9+355101 and Predictions for IceCube
Petropoulou, Maria; Oikonomou, Foteini; Giommi, Paolo (Peer reviewed; Journal article, 2020)3HSP J095507.9+355101 is an extreme blazar that has been possibly associated with a high-energy neutrino (IceCube-200107A) detected 1 day before the blazar was found to undergo a hard X-ray flare. We perform a comprehensive ... -

High-Energy Neutrino and Gamma-Ray Emission from Tidal Disruption Events
Murase, Kohta; Kimura, Shigeo; Zhang, Bing; Oikonomou, Foteini; Petropoulou, Maria (Peer reviewed; Journal article, 2020)Tidal disruption events (TDE) have been considered as cosmic-ray and neutrino sources for a decade. We suggest two classes of new scenarios for high-energy multi-messenger emission from TDEs that do not have to harbor ... -
A Neutral Beam Model for High-Energy Neutrino Emission from the Blazar TXS 0506+056
Zhang, Bing; Petropoulou, Maria; Murase, Kohta; Oikonomou, Foteini (Peer reviewed; Journal article, 2020)The IceCube collaboration reported an ~3.5σ excess of 13 ± 5 neutrino events in the direction of the blazar TXS 0506+056 during an ~6 month period in 2014–2015, as well as the (~3σ) detection of a high-energy muon neutrino ...
