Guide field effects on particle acceleration in three-dimensional relativistic magnetic reconnection
Despina Karavola, Lorenzo Sironi, Maria Petropoulou
Relativistic magnetic reconnection is a key mechanism for particle acceleration in astrophysical plasmas. Recent 3D particle-in-cell simulations have shown that, for weak guide fie…
Delayed Radio Flares in Neutrino-associated Blazars: The Case of TXS 0506+056
S. I. Stathopoulos, C. Yuan, G. Vasilopoulos +4
Radio flares have been postulated to be associated with the production of astrophysical neutrinos. For example, TXS 0506+056 exhibits a 2-3 yr delay between the 2017 IceCube-170922…
The role of Bethe-Heitler pair production in reconnection-driven flares in M87*
Maria Petropoulou, Despina Karavola, Lorenzo Sironi
Rapid TeV flares have been observed from the core of the active galaxy M87. These have been attributed to inverse Compton scattering of disk photons by electrons and positrons acce…
Diffuse neutrino flux from relativistic reconnection in AGN coronae
D. Karavola, M. Petropoulou, D. F. G. Fiorillo +3
IceCube observations point to Active Galactic Nuclei (AGN) as promising contributors to the observed astrophysical neutrino flux. Close to the central black hole, protons can be ac…
