The IXPE and multifrequency polarimetric view of the extreme blazars 1ES 1101-232 and RGB J0710+591
Fabrizio Tavecchio, Dawoon E. Kim, Gabriel Emery +53
Multiwavelength polarimetry is a powerful tool to probe magnetic field and flow geometries in the relativistic jets of blazars. In this respect, particularly interesting are the so…
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…
Do multifrequency polarimetric observations of BL Lac rule out a hadronic origin for its X-ray emission?
F. Tavecchio, F. Bolis, E. Sobacchi +2
Recent multifrequency polarimetric observations of the eponymous blazar BL Lac reveal an extremely large degree of polarization in the optical band (average of , reaching $45…
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…
Probing the low-energy particle content of blazar jets through MeV observations
F. Tavecchio, L. Nava, A. Sciaccaluga +1
Many of the blazars observed by Fermi actually have the peak of their time-averaged gamma-ray emission outside the GeV Fermi energy range, at MeV energies. The detail…
