************************************************** European VLBI Network Call for Proposals Deadline 1 February 2012 ************************************************** This text is also available on the web at http://www.jb.man.ac.uk/vlbi/EVN/call-feb12.txt Observing proposals are invited for the EVN, a VLBI network of radio telescopes spread throughout Europe and beyond, operated by an international Consortium of institutes (http://www.evlbi.org/). The observations may be conducted with disk recording (standard EVN) or in real-time (e-VLBI). The EVN facility is open to all astronomers. Use of the Network by astronomers not specialised in the VLBI technique is encouraged. The Joint Institute for VLBI in Europe (JIVE) can provide support and advice on project preparation, scheduling, correlation and analysis. See EVN User Support at http://www.jive.nl. Future Standard EVN Observing Sessions (disk recording) ------------------------------------------------------- 2012 Session 1 Feb 23 - Mar 15 18/21cm, 6cm ... 2012 Session 2 May 24 - Jun 12 18/21cm, 6cm ... 2012 Session 3 Oct 18 - Nov 08 18/21cm, 6cm ... Proposals received by 1 February 2012 will be considered for scheduling in Session 2, 2012 or later. Finalisation of the planned observing wavelengths will depend on proposal pressure. Future e-EVN Observing Sessions (real-time correlation) ------------------------------------------------------- 2012 Feb 07 - Feb 08 (start at 13 UTC) 6cm 2012 Mar 20 - Mar 21 (start at 13 UTC) 18/21cm, 6cm, 5cm or 1.3cm 2012 Apr 17 - Apr 18 (start at 13 UTC) 18/21cm, 6cm, 5cm or 1.3cm 2012 May 15 - May 16 (start at 13 UTC) 18/21cm, 6cm, 5cm or 1.3cm Please consult the e-EVN web page at http://www.evlbi.org/evlbi/e-vlbi_status.html to check for possible updates, and for the available array. e-VLBI proposals submitted by the February 1st deadline will be considered for scheduling in the above sessions starting from March 2012. Note that only one wavelength will be run in each session, depending on proposal priorities. See http://www.e-merlin.ac.uk/vlbi/evn_docs/guidelines.html for details concerning the e-VLBI observation classes and observing modes. Features for the next regular EVN and e-EVN sessions ----------------------------------------------------- * The antenna in Noto is under maintenance and it is expected to be available for EVN observations from Session 2, 2012. * Due to e-MERLIN commissioning VLBI at e-MERLIN out-stations (e.g. Cambridge) is not possible, and JB1 is the only homestation available. After commissioning, only separate EVN (Jb home-station only) and e-MERLIN observations will initially be scheduled. For updated information please consult the web at: http://www.e-merlin.ac.uk/vlbi/ Proposals requesting EVN + e-MERLIN should indicate clearly whether separate EVN and e-MERLIN observations are sufficient, or whether scheduling should await simultaneous VLBI at e-MERLIN outstations. Simultaneous wide-bandwidth VLBI and e-MERLIN operations at e-MERLIN outstations are planned for 2012. * Please consult http://www.evlbi.org/evlbi/e-vlbi_status.html and the EVN User Guide http://www.evlbi.org/user_guide/user_guide.html for updates on the current EVN and e-EVN array, availability of different stations per observing band and for the dates of the e-EVN observing sessions. Large EVN projects ------------------ Most proposals request 12-48hrs observing time. The EVN Program Committee (PC) also encourages larger projects (>48 hrs); these will be subject to more detailed scrutiny, and the EVN PC may, in some cases, attach conditions on the release of the data. How to submit ------------- All EVN, Global and e-VLBI proposals (except ToO proposals) must be submitted using the Northstar on-line proposal submission tool. Global proposals will be forwarded to NRAO automatically and should not be submitted to NRAO separately. New proposers should register at http://proposal.jive.nl. The SCIENTIFIC JUSTIFICATION MUST BE LIMITED TO 2 PAGES in length. Up to 2 additional pages with diagrams may be included. The deadline for submission is 23:59:59 UTC on 1 February 2012. Additional information ----------------------- Further information on Global VLBI, EVN+MERLIN and e-EVN observations, and guidelines for proposal submission are available at: http://www.e-merlin.ac.uk/vlbi/evn_docs/guidelines.html The EVN User Guide (http://www.evlbi.org/user_guide/user_guide.html) describes the network and provides general information on its capabilities. The current antenna capabilities can be found in the status tables. For the standard EVN see http://www.evlbi.org/user_guide/EVNstatus.txt For the e-EVN array see http://www.evlbi.org/evlbi/e-vlbi_status.html The On-line VLBI catalogue (http://db.ira.inaf.it/evn//) lists sources observed by the EVN and Global VLBI.
