The high-frequency (> 20 GHz), bright flux density (> 200 mJy) extragalactic radio sources (ERSs) population is dominated by blazars. Multi-frequency (and multi-epoch) polarimetry is invaluable to study magnetic fields and plasma in the inner and unresolved regions of their relativistic jets. Moreover, as ERSs constitute an important foreground for CMB, such studies are also crucial for...
The SPoCA-suite provide two modules, one for Active Region (AR) detection, and one for Coronal Holes(CH) detection, to the SDO Event Detection System (EDS). It runs in near-real times at Lockheed Martin Solar and Astrophysics Laboratory. Every four hours, the EDS generates and uploads the SPoCA entries into the AR and CH Catalogs of the HEK or Heliophysics Events Knowledgebase.

In this use-case presentation the EVN Archive and its provenance challenges will be presented.
The EVN is a proposal-driven open-access instrument for VLBI astronomy. There is considerable interest -- not least from funding agencies -- about the conversion of the data taken into papers published in the scientific literature (which in our case can be restricted to those registered in the...
