Description
Relativistic Jets from AGN are prime sources for cosmic neutrinos and other high energy particles, and likely act as a main force to regulate star formation and evolution in their host galaxies. The precise details of the jet launching mechanism, particle content, and energetics of the emitting electrons are still poorly understood. These questions can be tackled by investigating the polarized properties of the jet across frequencies, preferably as close to the jet base as possible. I will briefly describe the ongoing efforts to produce resolved rotation measure maps of the blazer 3C273 at the highest resolutions possible using 230 GHz EHT observations from 2021. The EHT allows for high SNR measurements of polarization properties in AGN at resolutions approaching 10 muas, providing an unprecedented window to analyze the formation and structure of relativistic jets.
