SUMMARY:IAU Symposium 2027
DESCRIPTION:January 18th – January 22nd\, 2027 in Windhoek\, Namibia \nRelativistic jets from active galactic nuclei are among the Universe’s most extreme particle accelerators. Blazars\, with jets pointed toward Earth\, show dramatic multiwavelength variability and gamma-ray flares\, offering unique insights into particle acceleration\, jet dynamics\, and magnetic field structure. Yet key processes\, such as jet formation\, the location of high-energy emission\, and the mechanisms driving flares\, remain poorly understood. This symposium brings together theorists\, observers\, and instrument scientists to address these challenges\, focusing on universal jet physics across systems\, including jet launching and collimation\, particle acceleration\, magnetic-field evolution\, multi-band flaring and polarisation signatures\, and multimessenger links involving neutrinos. Comparative insights from other jetted sources\, such as GRBs\, TDEs\, and Galactic accreting systems\, will broaden the scientific perspective. Building on the progress surrounding the African Millimetre Telescope in Namibia and the continued success of H.E.S.S.\, MAGIC\, VERITAS\, MeerKAT\, EHT\, SALT\, and Fermi\, and the upcoming SKA\, Vera C. Rubin Observatory\, CTAO\, and ASTRI Mini-Array\, this meeting will advance multimessenger studies\, foster international collaboration\, and engage early-career researchers and the growing African astronomy community. \nThe IAUS 413 will focus on recent studies in these fields and potential future prospects and synergies among them. During this meeting\, the topics we will discuss include: \n\nUniversal dynamics & modelling: Identify fundamental processes of jet formation\, composition\, and acceleration across AGN\, GRBs\, and XRBs by employing advanced RMHD and PIC simulations to unify observed universal jet behaviours.\nEmission & localisation: Characterise high-energy emission zones within relativistic outflows by analysing jet structure and magnetic-field evolution across diverse accretion and power regimes\, from Galactic sources to the most distant quasars.\nMultimessenger synergy: Evaluate the physical connections between flaring activity\, neutrino production\, and candidate multimessenger sources to build integrated theoretical frameworks for jet phenomena across all mass scales.\nPolarimetry & variability: Utilise multi-band flares\, multiwavelength variability\, and polarisation signatures as high-fidelity probes to decode internal jet physics and particle acceleration mechanisms in X-ray Binaries and AGN.\nComparative astrophysics & scaling laws: Conduct cross-system studies (TDEs\, AGN\, and Galactic XRBs) to determine if particle acceleration and energy dissipation mechanisms are truly scale-invariant or fundamentally altered by the local environment.\n\nDetails\nThe 2027 IAUS413 will be held between January 18th – 22nd\, 2027\, in Windhoek\, Namibia\, making it the 5th African country ever to host such an event. The abstract submission/travel grant application deadline is July 15th and the registration deadline August 15th 2026.
