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…

Determining the origin of the X-ray emission in blazars through multiwavelength polarization

Ioannis Liodakis, Haocheng Zhang, Stella Boula +48

The origin of the high-energy emission in astrophysical jets from black holes is a highly debated issue. This is particularly true for jets from supermassive black holes that are a…

How do recollimation-induced instabilities shape the propagation of hydrodynamic relativistic jets?

A. Costa, G. Bodo, F. Tavecchio +4

Recollimation is a phenomenon of particular importance in the dynamic evolution of jets and in the emission of high-energy radiation. Additionally, the full comprehension of this p…
