Access to the EVN

The EVN is an "open-skies" facility and encourages use of the network by astronomers not specialised in the VLBI technique. All scientists, whether or not affiliated to EVN consortium institutes, can obtain observing time on the EVN via the standard peer-review selection process.

All EVN users receive:

• EVN observations and absentee correlation of the data.
• JIVE Support Scientist Assistance - a JSS is assigned to each project. The JSS is available to directly support scheduling the observation, correlation of the data, and post-correlation analysis. Visitor support facilities at JIVE include four high-end workstations running AIPS, Difmap, and other useful packages.

Acknowledgments:

Publications resulting from your EVN observations should carry the standard EVN acknowledgment:

The European VLBI Network is a joint facility of independent European, African, Asian, and North American radio astronomy institutes. Scientific results from data presented in this publication are derived from the following EVN project code(s):

(Fill in the appropriate project codes at the end of this acknowledgment; in this sense, the "project code" should be the 5-character code, without the final letter that distinguishes between multiple epochs and/or frequency bands, if applicable.)

Publications resulting from e-VLBI observations with the EVN should also carry the standard NEXPReS acknowledgment:

e-VLBI research infrastructure in Europe is supported by the European Union's Seventh Framework Programme (FP7/2007-2013) under grant agreement number RI-261525 NEXPReS.

Publications from observations including the RadioAstron orbiting antenna should also include:

The RadioAstron project is led by the Astro Space Center of the Lebedev Physical Institute of the Russian Academy of Sciences and the Lavochkin Scientific and Production Association under a contract with the Russian Federal Space Agency, in collaboration with partner organizations in Russian and other countries.

EVN Trans-national access via RadioNet

Starting from 1 March 2021, the Opticon RadioNet Pilot program starts, funded by the EC Horizon 2020 Research and Innovation Programme. This re-establishes the possibility of new travel subsidies for members of the research teaasm of eligible projects via the trans-national access (TNA) program. For the EVN, "eligible" in general means that:

• The PI is from an institute in a country of the EU or Associated States.
• The same criterion, but applied collectively to 50% or more of the individual members of the research team.
• The research team is defined by the co-authors listed on the observing proposal, and the association of researcher with institute remains fixed at that shown on the proposal.

The trans-national access support includes travel reimbursement for visits to JIVE in order to analyse and process EVN, EVN-MERLIN or global VLBI Data. In general, the PI may select one member of the project team to receive this travel support.

Further information on access to the EVN through the EC's RadioNet TNA program can be obtained from Bob Campbell.

How Do I Apply?

EVN Users who wish to take advantage of this programme should submit EVN Observing Proposals (see the EVN User Guide) in the usual way. If the Proposal is accepted by the EVN PC and scheduled then the user will gain automatic access to this support program. Users need not do anything further and will be notified once the experiment is placed on the EVN block schedule.

Requested TNA Acknowledgment

If you have a project that is eligible for support via the Opticon RadioNet Pilot TNA program, or previous RadioNet TNA programs, would you please include the appropriate acknowledgment in papers, conference proceedings, etc. that result from the project:
