Supermassive black holes at the center of active galactic nuclei (AGN) power some of the most luminous objects in the Universe). In particular, blazars are a subclass of AGNs where a relativistic jet of plasma is ejected from the surroundings of the central engine and points towards Earth with a very low inclination angle, which makes them very bright at radio wavelengths as a consequence of Doppler beaming and suitable for very long baseline interferometric (VLBI) observations.

6.7 GHz methanol masers serve as crucial signal indicators in the context of high-mass star formation. It is believed that these Class II masers are radiation-pumped, and as such, their variability is closely linked to the variability of protostars. This connection renders the study of the variability of 6.7 GHz methanol masers a promising tool for investigating processes during high-mass star formation.

Welcome to the January 2024 issue of the EVN/JIVE newsletter.

Happy New Year and I hope 2024 will bring continued scientific success to the EVN Community. This year marks the 40th anniversary of the formal constitution of the EVN: the signing of the EVN Memorandum of Understanding took place shorty after a meeting of the EVN Directors in Vienna in June 1984. That year also saw the first, and very successful, World Array’ VLBI experiments using 18 antennas in a global array (including MERLIN) and the first EVN observations with the new 32-m telescope at Medicina.

A new system for station experiment feedback has been implemented. Feedback can be added through the EVN Mattermost via the command '/feedback' (for the most recent session) or (e.g.) '/feedback 2023/2' for Session 2 of 2023. 

A form should pop up to fill in the details, as shown below.  For now, the Mattermost interface is write-only; feedback can be reviewed here.

Welcome to the September 2023 issue of the EVN/JIVE Newsletter.

The EVN Consortium Directors met during the VLBI40 Conference in Bologna in May. The Bologna conference was a fantastic demonstration of the demand for, interest in and science output from VLBI and the EVN in particular.
