Role of magnetic reconnection in blazar variability using numerical simulation
Chandan Kumar Das, Bhargav Vaidya, Amit Shukla +2
Fast -ray variability in blazars remains a central puzzle in high-energy astrophysics, challenging standard shock acceleration models. Blazars, a subclass of active galactic nu…

Multidimensional half-moment multigroup radiative transfer. Improving moment-based thermal models of circumstellar disks
David Melon Fuksman, Mario Flock, Hubert Klahr +2
Common moment-based radiative transfer methods, such as flux-limited diffusion (FLD) and the M1 closure, suffer from artificial interactions between crossing beams. In protoplaneta…

Spectral and magnetic properties of the jet base in NGC 315
L. Ricci, B. Boccardi, J. Roeder +7
The dynamic of relativistic jets in the inner parsec regions is deeply affected by the nature of the magnetic fields. The level of magnetization of the plasma, as well as the geome…
