11th European VLBI Network Symposium & Users Meeting

11th EVN Symposium - (other evn conferences)
9-12 October, 2012
Bordeaux (France)
published January 22, 2016
The Laboratoire d'Astrophysique de Bordeaux (LAB) at the University of Bordeaux (France), on behalf of the European VLBI Consortium, hosted the 11th European VLBI Network (EVN) Symposium and EVN Users Meeting on October 9-12, 2012. The Symposium was held at the "Chambre de Commerce et d'Industrie de Bordeaux", located in the "Palais de la Bourse", in the center of Bordeaux. The conference highlighted the latest scientific results and technical developments from VLBI, space VLBI and e-VLBI. All fields of astrophysics were concerned - stellar, galactic and extragalactic - as well as astrometry and planetary science. Presentations addressing synergy between (e-)VLBI and other new or planned radio facilities (ALMA, LOFAR, e-MERLIN,...) or instruments at other wavelengths (Fermi, CTA, Gaia,...) were also an integral part of the program. The scientific program was organized in 11 sessions including 71 oral presentations, with an additional 43 posters available for viewing during the entire length of the conference. An EVN Users Meeting was also held during one of the evening to foster interaction between the EVN users and the EVN organization. The symposium was attended by a total of 122 delegates originating from 47 institutes world-wide, sharing new VLBI science and innovations while also building links with other communities.

The research leading to these results has received funding from the European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement no 283393 (RadioNet3).
