Special Issue in Galaxies: Polarimetry as a Probe of Magnetic Fields in AGN Jets
The specific conditions required for its production and transmission make the polarized emission from astrophysical plasmas an invaluable probe of the physical processes occurring in their environments. In astrophysical jets, magnetized plasma is accelerated to relativistic energies, driving the emergence of intrinsically polarized incoherent synchrotron processes. The often-overwhelming challenges—both observational and theoretical—involved in the study of polarized emission have notably delayed the exploitation of this unique potential tool.
The subject of the international conference, "Polarised Emission from Astrophysical Jets", held in Ierapetra (Greece), 12–16 June, 2017, has been the comprehensive review of the theoretical and observational aspects related to linearly and circularly polarized emission observed from extragalactic (AGN, GRBs), as well as galactic (e.g., XRBs), astrophysical jets, and their potential to reveal the physical conditions and emission processes governing these sources.
The meeting focuses on current polarimetric monitoring programs, as well as high angular resolution interferometric observations, and prospects for new facilities (i.e., ALMA, SKA, EHT, XIPE, e-ASTROGAM). Special attention was paid on reviewing current models for linear and circular polarization (including Faraday effects), and its relation to the jet magnetic field topology, composition, propagation, and formation. Contributions were invited on topics such as:
- Theories for linear and circular polarization emission models
- Propagation of polarized emission and Faraday rotation effects
- Magnetic field structure and its role in the jet dynamics
- Jet formation and composition
- Polarization variability
- Polarimetric monitoring programs
- High angular resolution polarimetric observations
- Prospects for high energy (X-ray, gamma-ray) polarimetry
The conference was hosted at the Foundation of Cultural and Social Care of the Metropole of Ierapetra and Sitia in the southernmost town of Europe, Ierapetra, located on the southern coast of Eastern Crete in the prefecture of Lasithi.
