Ultraheavy Ultrahigh-Energy Cosmic Rays
B. Theodore Zhang, Kohta Murase, Nick Ekanger +2
We investigate the propagation of ultraheavy (UH) nuclei as ultrahigh-energy cosmic rays (UHECRs). We show that their energy loss lengths at EeV are significantly lon…
Multimessenger Constraints on Production Sites of High-Energy Neutrinos from NGC 1068
Abhishek Das, Kohta Murase, B. Theodore Zhang
The detection of high-energy neutrino signals from the nearby Seyfert galaxy NGC 1068 provides us with a unique opportunity to explore nonthermal processes near the center of super…
Multimessenger Prospects for Low-Luminosity Gamma-Ray Bursts: Joint Neutrino and X-Ray Observations
Wenkang Lian, He Gao, Shunke Ai +1
Low--luminosity gamma-ray bursts (LLGRBs) are promising candidates for high-energy neutrinos, yet no coincident neutrino events have been detected so far. Recent advances in X-ray…
Unveiling Multimessenger Emission from Hidden Cores of Microquasars
Yu-Jia Wei, Kohta Murase, B. Theodore Zhang
Microquasars are radio-emitting X-ray binaries accompanied by relativistic jets. They are established sources of 100~TeV gamma rays and are considered promising candidates for cosm…
Microquasar jet-cocoon systems as PeVatrons
B. Theodore Zhang, Shigeo S. Kimura, Kohta Murase
The origin of Galactic cosmic rays (CRs), particularly around the knee region (3 PeV), remains a major unsolved question. Recent observations by LHAAASO suggest that the knee…
Neutrino and Electromagnetic Signals from Tidal Disruption Events: Bridging the Theory with Observations
Chengchao Yuan, Walter Winter, Cecilia Lunardini +3
This proceeding presents recent results from a joint analysis of time-dependent neutrino and electromagnetic emissions from tidal disruption events (TDEs), using both isotropic win…
