European VLBI Network Mini-Symposium and Users' Meeting 2021

The European VLBI Network Symposium is the main forum for discussion of the latest Very Long Baseline Interferometry scientific results and technical and technological developments within the EVN member countries. Due to the Covid-19 pandemic, it was not possible to hold this Symposium in 2020 as originally planned; instead, an online EVN Mini-Symposium and Users Meeting was held during July 12-14, 2021. Topics covered ranged from radio-emitting processes around stars to the innermost structure of active galactic nuclei and the origin of astrophysical jets, and a number of technical topics were also considered.
