2D magnetohydrodynamic jet simulations: properties of recollimation shocks
Stella Boula, Fabrizio Tavecchio, Gianluigi Bodo +2
Recollimation shocks are a frequent outcome in overpressured relativistic jets and are crucial for interpreting stationary features in Active Galactic Nuclei. The precise influence…
Instabilities at recollimation shocks in MHD jets
Stella Boula, Fabrizio Tavecchio, Gianluigi Bodo +4
AGN jet structure and stability remain uncertain; recollimation shocks are linked to morphology and variability, but the role of downstream instabilities is still unclear. We aim t…
Exploring the impact of electromagnetic dissipation on ultra-relativistic plasma outflows
Argyrios Loules, Nektarios Vlahakis
Ultra-relativistic plasma outflows are intrinsically connected with gamma-ray bursts. Over the years, a large number of analytical and numerical works has been devoted to understan…
Modeling of resistive relativistic astrophysical jets. Semianalytic results following a paraxial formalism
Argyrios Loules, Nektarios Vlahakis
Relativistic jets of magnetized plasma are a common high-energy astrophysical phenomenon, observed across a wide range of spatial and energy scales. In the past, semianalytic merid…
Classical waves and instabilities using the minimalist approach
Nektarios Vlahakis
The minimalist approach in the study of perturbations in fluid dynamics and magnetohydrodynamics involves describing their evolution in the linear regime using a single first-order…
