Instabilities in Cylindrical Geometry Using the Minimalist Approach: Formalism and Rotational Instabilities

Nektarios Vlahakis

The minimalist approach for linear stability analysis is applied to fluids and magnetized ideal plasmas in cylindrical geometry. In this approach, the dispersion relation is obtain…

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…
