Compact radio galaxies: the case of FR0s

R. D. Baldi, A. Capetti, G. Giovannini +20

Fanaroff-Riley type 0 (FR0) radio galaxies, a newly-identified and abundant population of low-power radio-loud active galactic nuclei, present a significant challenge to our unders…

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…
