European VLBI Network
Call for Proposals
Deadline 1st February 2016

[cid:AF18511B-8932-41E0-81C4-AAA0105F9511]


The European VLBI (Very Long Baseline Interferometry) Network (EVN, http://www.evlbi.org/) is a network of radio telescopes in Europe, Asia, North America and South Africa, which allows imaging at radio wavelengths with millarcsecond resolution (from 0.001'' to 0.1'') using the VLBI technique. Wavelengths covered are from 0.7 cm (43 GHz) to 90 cm (345 MHz). The EVN facility is open to all astronomers. Use of the Network by astronomers not specialised in the VLBI technique is encouraged. Advice on the feasibility of possible projects or help with preparing proposals is available from the Joint Institute for VLBI ERIC (JIVE) in the Netherlands (http://www.jive.eu/evn-user-support-jive).

The next proposal deadline is February 1st 2016. Further details and web links to the EVN are available via the formal call for proposals at: http://www.oso.chalmers.se/evn/call.txt

VLBI continuum observations generally observe high brightness temperature radio emission from synchrotron or gyro-synchrotron processes with thermal emission detectable on short baselines. Radio spectral lines are observable in maser emission (mainly OH, H2O, CH3OH, and SiO) and in absorption against bright continuum sources (mainly in HI and OH). Full polarisation observations (VLBI data routinely return linear polarization measurements) for continuum and spectral line allow detection and estimation of magnetic fields and ionised gas densities via Zeeman splitting, Faraday rotation, and Faraday depolarisation mechanisms. VLBI has the extreme angular resolution to follow changes in source structure on timescales of hours (for stars), months (for many Galactic objects), and years (for many high-redshift systems). Absolute and relative astrometry of compact radio structure is possible at the (sub)milliarsecond level, which for Galactic objects allows the measurement of both parallax and proper motion to be made.

Science highlights from the network were presented at the latest EVN Symposium:

Further information on EVN observations, and guidelines for proposal submission are available at:

The EVN User Guide (http://www.evlbi.org/user_guide/user_guide.html) describes the network and provides general information on its capabilities.

Apologies if you have already received this message and for any cross-posting.

Best regards,
