A Turbulence-Driven Magnetic Reconnection Model for the High-Energy Neutrino Emission from NGC 1068
Luana Passos-Reis, Elisabete M. de Gouveia Dal Pino, Juan C. Rodríguez-Ramírez +1
We model the Seyfert II AGN NGC 1068 within a turbulence-induced magnetic reconnection framework to explain its high-energy emission. Observations reveal a neutrino flux excess hig…
High-Energy Neutrino Emission in NGC1068 driven by Turbulent Magnetic Reconnection
Luana Passos-Reis, Elisabete M. de Gouveia Dal Pino, Juan C. Rodríguez-Ramírez +1
Astrophysical neutrinos from Active Galactic Nuclei (AGN) offer a unique window into high-energy particle acceleration in obscured environments. The nearby Type II Seyfert galaxy N…
Is plasmoid-mediated reconnection really important in accretion flows to drive flares in AGNs?
Giovani H. Vicentin, Elisabete M. de Gouveia Dal Pino, George N. Wong +4
Based on very high-resolution resistive 2D and 3D magnetohydrodynamical (MHD) simulations of current sheets, our findings suggest that the answer to this question is likely no. In…
Testing the Spacetime Geometry of Sgr A* with the Relativistic Orbit of S2 star
Parth Bambhaniya, Preet Dalal, Giovani H. Vicentin +3
In this work, we perform a relativistic test of the spacetime geometry of Sagittarius A* (Sgr A*) using the orbit of the S2 star. We consider a broad class of compact object models…
Cosmic Ray Acceleration by Turbulence-Driven Magnetic Reconnection and the Origin of the Neutrinos in NGC 1068
Luana Passos-Reis, Elisabete M. de Gouveia Dal Pino, Juan Carlos Rodríguez-Ramírez +1
The Seyfert Type II galaxy NGC 1068 has been identified as a potential neutrino source by IceCube, with a 4.2 significance detection of a 79 neutrino excess from 2…
Do plasmoids induce fast magnetic reconnection in well-resolved current sheets in 2D MHD simulations?
G. H. Vicentin, G. Kowal, E. M. de Gouveia Dal Pino +1
We investigate the development of tearing-mode instability using the highest-resolution two-dimensional magnetohydrodynamic simulations of reconnecting current sheets performed on…
Particle acceleration by turbulent-driven magnetic reconnection and the production of gamma-rays and neutrinos in AGNs
E. M. de Gouveia Dal Pino, J. C. Ramirez-Rodriguez, T. Medina-Torrejon +2
3D Magnetohydrodynamic (MHD) resistive simulations have highlighted the significance of ubiquitous turbulence to drive fast reconnection. It has been demonstrated that particle acc…
Investigating Turbulence Effects on Magnetic Reconnection Rates Through Three-Dimensional Resistive Magnetohydrodynamical Simulations
Giovani H. Vicentin, Grzegorz Kowal, Elisabete M. de Gouveia Dal Pino +1
We investigate the impact of turbulence on magnetic reconnection through high-resolution 3D magnetohydrodynamical (MHD) simulations, spanning Lundquist numbers from to $10…
