AGN Jets from Formation to Dissipation
A. -K. Baczko, Eleni Vardoulaki, Etienne Bonnassieux +26
Active Galactic Nuclei (AGN) are among the most energetic phenomena in the Universe, capable of launching powerful relativistic jets that extend from sub-parsec to megaparsec scale…
VIPCALs: A fully automated calibration pipeline for very long baseline interferometry data
Diego Ãlvarez-Ortega, Carolina Casadio, Felix M. Pötzl +2
Very long baseline interferometry (VLBI) is a powerful technique that can achieve sub-milliarcsecond resolution. However, it requires complex and often manual post-correlation cali…
SMILE: Discriminating milli-lens systems in a VLBI pilot project
F. M. Pötzl, C. Casadio, G. Kalaitzidakis +11
Dark Matter (DM) remains poorly probed on critical, sub-galactic scales, where predictions from different models diverge in terms of abundance and density profiles of halos. Gravit…
A multi-frequency study of sub-parsec jets with the Event Horizon Telescope
Jan Röder, Maciek Wielgus, Andrei P. Lobanov +287
The 2017 observing campaign of the Event Horizon Telescope (EHT) delivered the first very long baseline interferometry (VLBI) images at the observing frequency of 230 GHz, leading…
