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…
VLBA observations of a sample of low-power compact symmetric objects
M. Orienti, F. D'Ammando, D. Dallacasa +3
Compact symmetric objects (CSOs) are intrinsically compact extragalactic radio sources that are thought to be the progenitors of classical radio galaxies. To date, evolutionary mod…
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…
