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…
A generalized study of linear electromagnetic cascades in astrophysical sources
Damiano F. G. Fiorillo, Federico Testagrossa, Chengchao Yuan +2
High-energy gamma rays can trigger electromagnetic cascades via pair production on ambient photons, reprocessing their energy to lower frequencies. A classic example is the cascade…
An Accretion Flare Interpretation for the Ultra-High-Energy Neutrino Event KM3-230213A
Chengchao Yuan, Leonard Pfeiffer, Walter Winter +4
We study the origin of the ultra-high-energy (UHE) neutrino event KM3-230213A detected by KM3NeT, focusing on MRC 0614-083 which has been pinpointed as the closest blazar to the ne…
Can the neutrinos from TXS 0506+056 have a coronal origin?
Damiano F. G. Fiorillo, Federico Testagrossa, Maria Petropoulou +1
The blazar TXS 0506+056 has been the first astrophysical source associated with high-energy astrophysical neutrinos, and it has emerged as the second-most-prominent hotspot in the…
