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…
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…
Neutrino and pair creation in reconnection-powered coronae of accreting black holes
D. Karavola, M. Petropoulou, D. F. G. Fiorillo +2
A ubiquitous feature of accreting black hole systems is their hard X-ray emission which is thought to be produced through Comptonization of soft photons by electrons and positrons…
Diffuse neutrino flux from coronal magnetospheric current sheets of accreting black holes
Despina Karavola, Maria Petropoulou, Damiano F. G. Fiorillo +2
Non-jetted AGN exhibit hard X-ray emission with a power law spectrum above 2 keV, which is thought to be produced through Comptonization of soft photons by electrons and posi…
Accelerating SED Modeling of Astrophysical Objects Using Neural Networks
Federico Testagrossa, Georgios Vasilopoulos, Despina Karavola +4
Interpreting the spectral energy distributions (SEDs) of astrophysical objects with physically motivated models is computationally expensive. These models require solving coupled d…
