************************************************** European VLBI Network Call for Proposals Deadline 1st June 2012 ************************************************** This text is also available on the web at http://www.jb.man.ac.uk/EVN-Call/call-jun12.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 3 Oct 18 - Nov 08 18/21cm, 6cm ... 2013 Session 1 Feb 21 - Mar 14 18/21cm, 6cm ... Proposals received by 1st June 2012 will be considered for scheduling in Session 3, 2012 or later. Finalisation of the planned observing wavelengths will depend on proposal pressure. Future e-VLBI Observing Sessions (real-time correlation) ------------------------------------------------------- 2012 Sep 17 - Sep 18 (start at 13 UTC) 18/21cm, 6cm, 5cm or 1.3cm 2012 Oct 09 - Oct 10 (start at 13 UTC) 18/21cm, 6cm, 5cm or 1.3cm 2012 Nov 13 - Nov 14 (start at 13 UTC) 18/21cm, 6cm, 5cm or 1.3cm Please consult the e-VLBI 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 June 1st deadline will be considered for scheduling in the above sessions starting from Sep 2012. Note that only one wavelength will be run in each e-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-VLBI sessions ----------------------------------------------------- * The antenna in Noto has now completed its maintenance program and will be available for EVN observations from Session 2, 2012. * e-VLBI updates: e-VLBI is now available with Noto telescope at 512Mbps. Full 1Gbps e-VLBI data transmission is now possible from Medicina. * The antennas at Shanghai and Urumqi are required for spacecraft tracking duties during Sep - Nov 2012. This may impact their availability for EVN operations in Session 3 2012. * The VLBA antennas, which are used in Global proposals, are not available between GST 21:00 and 06:00 from Sep to Nov (All of Session 3 2012) * From Session 3 2012, both Jb1 and Jb2 will be available for EVN recording, as will simultaneous EVN+e-MERLIN operations with home- station EVN recording. For simultaneous EVN+e-Merlin operations, VLBI data for Cm will be made available at up to 512Mbps on a best efforts basis. For updated information please consult the web at: http://www.e-merlin.ac.uk/vlbi/ * 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-VLBI array, availability of different stations per observing band and for the dates of the e-VLBI 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 June 2012. Additional information ----------------------- Further information on Global VLBI, EVN+MERLIN and e-VLBI 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-VLBI 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.
