An international team of researchers used multi-wavelength observations of active galactic nuclei to study how black holes launch relativistic jets. The sixteen sources were observed with the Event Horizon Telescope during its first campaign in 2017. The extreme resolution achieved by the Event Horizon Telescope enabled studies of jets closer than ever to the central supermassive black holes of these galaxies. The team investigated the acceleration and magnetization of the jets by comparing results obtained at various frequencies and angular scales. The work was led by scientists from Max Planck Institute for Radio Astronomy (MPIfR) in Bonn/DE, and the Instituto de Astrofisica de Andalucia (IAA-CSIC) in Granada/ES. The results are published in the journal Astronomy & Astrophysics: A multifrequency study of sub-parsec jets with the Event Horizon Telescope, DOI https://doi.org/10.1051/0004-6361/202452600.
