X-ray polarimetry promises us an unprecedented look at the structure of magnetic fields and
on the processes at the base of acceleration of particles up to ultrarelativistic energies in …

The lower-energy peak of the spectral energy distribution of blazars has commonly been
ascribed to synchrotron radiation from relativistic particles in the jets. Despite the consensus …

Magnetic reconnection in relativistic plasmas is well established as a fast and efficient
particle accelerator, capable of explaining the most dramatic astrophysical flares. With …

X-ray polarization, which now can be measured by the Imaging X-ray Polarimetry Explorer
(IXPE), is a new probe of jets in the supermassive black hole systems of active galactic …

We investigate with relativistic MHD (magnetohydrodynamic) simulations the dissipation
physics of BL Lac jets, by studying the synchrotron polarization signatures of particles …

It is commonly believed that blazar jets are relativistic magnetized plasma outflows from
supermassive black holes. One key question is how the jets dissipate magnetic energy to …

Magnetic reconnection is often invoked as a source of high-energy particles, and in
relativistic astrophysical systems it is regarded as a prime candidate for powering fast and …

Blazars are relativistic magnetized plasma outflows from supermassive black holes that
point very close to our line of sight. Their emission is nonthermal-dominated and highly …

Relativistic magnetic reconnection is a potential particle acceleration mechanism for high-
frequency BL Lac objects (HBLs). The Imaging X-ray Polarimetry Explorer (IXPE) scheduled …

Study of the polarization behaviour in blazars is a powerful tool to discern the role of the
magnetic field in the variable emission process in their relativistic jets. We present here the …
