Rationale

Energetic and collimated beams of plasma launched from the center of galaxies have fascinated the community for a century. In spite of the advancement in observational and theoretical modeling techniques, many aspects regarding the detailed physics of extragalactic jets remain not fully understood. This symposium aims to push forward our understanding of extragalactic jets bringing together experts from theory and observations.

One major aim of the proposed symposium is to demonstrate recent advances in the multi-scale numerical modeling of jets and to discuss strategies for how to better constrain simulations with multi-wavelength and high-resolution observational data. Another focus shall be the universality of jet properties and understand what we can learn from other jet sources such as non-relativistic jets or gamma-ray bursts.

The proposed symposium will address astrophysics across all scales of the jets from :
- the launching scale that governs the jet foot point, jet energetics, and matter content
- the propagation scale involving magnetic dissipation, particle acceleration, and non-thermal radiation, jet stability, variability, and jet-medium interaction
- the termination scale that is essentially connected to ISM, IGM and ICM feedback, and radio jet power and morphology

Present and future sensitive radio facilities, such as VLA, LOFAR, uGMRT, MeerKAT, EHT, ALMA, and SKA, together with those extending the coverage over a full multi-wavelength range.
In particular, the high-energy regime (such as ATHENA, HESS, or CTA), will be crucial for unraveling the physics of extragalactic jets at all spatial scales.
This symposium would be a platform to discuss state-of-the-art astrophysical approaches which can successfully bridge between numerical simulations, theoretical models, and multi-wavelength/multi-messenger observations.
