TeV Gamma-Rays from the Low-Luminosity Active Galactic Nucleus NGC 4278: Implications for the Diffuse Neutrino Background
Chengchao Yuan, Ruo-Yu Liu
This work investigates the origin of the TeV emission detected by the Large High Altitude Air Shower Observatory (LHAASO) from NGC~4278, a galaxy hosting a low-luminosity active ga…
A White Dwarf Tidal Disruption by an Intermediate-Mass Black Hole as the Progenitor of Ultra-long GRB 250702B
Chengchao Yuan, Ning Jiang, Zi-Gao Dai
The recent detection of GRB 250702B, the longest gamma-ray burst observed to date with prompt emission lasting seconds, challenges the conventional collapsar…
A neutrino flare candidate potentially associated with X-ray emission from tidal disruption event ATLAS17jrp
Rong-Lan Li, Chengchao Yuan, Hao-Ning He +5
Tidal disruption events (TDEs), in which stars are disrupted by supermassive black holes, have been proposed as potential sources of high-energy neutrinos through hadronic interact…
Coupled Time-Dependent Proton Acceleration and Leptonic-Hadronic Radiation in Turbulent Supermassive Black Hole Coronae
Chengchao Yuan, Damiano F. G. Fiorillo, Maria Petropoulou +1
Turbulent coronae of supermassive black holes can accelerate non-thermal particles to high energies and produce observable radiation, but capturing this process is challenging due…
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…
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…
