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…
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…
The polarization of the synchrotron radiation from a recollimated jet: application to high-energy BL Lacs
Alberto Sciaccaluga, Agnese Costa, Fabrizio Tavecchio +3
Multifrequency polarimetry, recently extended to the X-ray band thanks to the Imaging X-ray Polarimetry Explorer (IXPE) satellite, is an essential tool for understanding blazar jet…
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…
IXPE Observation of the Low-Synchrotron Peaked Blazar S4 0954+65 During An Optical-X-ray Flare
Pouya M. Kouch, Ioannis Liodakis, Francesco Fenu +134
The X-ray polarization observations made possible with the Imaging X-ray Polarimetry Explorer (IXPE) offer new ways of probing high-energy emission processes in astrophysical jets…
