Abstract:

The vast majority of astronomical EVN experiments, and about half of the global experiments, are now correlated at JIVE. Processing continuum, cross-polarization, phase-reference, or spectral-line experiments is now essentially routine. Since the Barcelona meeting we have significantly increased throughput and efficiency, in terms of boosting physical limits, reducing vulnerability to various bugs, developing new astronomical capabilities, and strengthening liaison procedures with PIs. The move to Mark5 and fiber-linked VLBI (e-VLBI) is already underway. Small-scale test observations have been carried out in both areas. In the longer term, we have entered into a proof-of-concept project with a pan-European gigabit research network (GÉANT) and various national research and educational networks to demonstrate the feasibility of real-time correlation among EVN stations.
