Circular 5: ESO Spectroscopic Surveys: Aceptadas las dos LoIEstimados colegas de la REG,ESO ha valorado muy favorablemente las dos LoI presentadas por los equipos de Gaia! Os adjuntamos los correos de Bruno Leibundgut (ESO), con los comentarios específicos del panel de revisión, y los de Gerry Gilmore (SE1/2) y Sofia Randich (SE3), coordinadores de las dos propuestas. Vereis que se nos propone juntar ambos proyectos optimizando así los surveys en el disco galáctico y nos animan a trabajar duro para la redacción de la propuesta definitiva, que entendemos deberá estar lista a finales de marzo. Queda poco tiempo por lo que dudeis en informar directamente a toda la REG de los pasos que cada uno de vosotros vayais dando, así podremos ver en que tareas podemos ir aumentando la participación española en el proyecto. Un abrazo, Francesca --------------------------------------------------------------------------------------------------------------------------------------- Gerry Gilmore wrote: Dear Gaia-ESO large spectroscopic survey colleagues From: Bruno Leibundgut <bleibund@eso.org> To: gil@ast.cam.ac.uk Cc: opo@eso.org, bleibundgut@eso.org, tdezeeuw@eso.org Subject: ESO Public Spectroscopic Surveys Garching, 5 February 2011 Dear Gerry, Thank you very much for submitting a letter of intent for an ESO Public Spectroscopic Survey entitled The Gaia-ESP Survey: Galactic Astrophysics via VISTA Imaging, Gaia Astrometry, and ESO Spectroscopy. ESO received 24 letters of intents for spectroscopic surveys asking for a total of over 4000 nights using 9 different instruments. The evaluation was done by a specially convened panel of six eminent scientists. The 24 letters of intent were carefully examined and discussed in a face-to-face meeting at ESO Garching at the end of January. The panel paid special attention to the legacy aspect of the proposed surveys. As stated in the Call for Letters of Intent, only very few surveys can be implemented. We would like to invite you to submit a proposal for a public spectroscopic survey. However, the panel felt that the synergies with the project proposed by Sofia Randich (Arcetri) are significant and a merged proposal would be considered very favourably. It is clear that only one proposal can be accepted, and should you submit an independent proposal, it will be judged against the other submission. Please take the comments by the panel into account for your proposal. The specific panel comments for your project reads: The PSSP was impressed with this proposal and recommends that the proposers submit a full proposal which should justify clearly why such a large amount of time is needed, and how the accumulated data will complement and extend the science that will be done by other recent and ongoing spectroscopic surveys (SEGUE, RAVE, APOGEE..). It is notable that rather little data will be obtained on the thin disk which is by a substantial margin the dominant stellar component of the Milky Way by mass. This could be rectified by coordination with a survey of disk clusters which has been suggested by the cluster community (also using FLAMES) and which the PSSP is also recommending to submit a full proposal. Splitting the amount of survey time available with FLAMES between the two programmes would give a more complete overview of the stellar populations of the Galaxy. Yours Faithfully, Bruno. ------------------------------------------------------------------- Sofia Randich wrote: Dear CoIs of the cluster LoI, I have just received very good news from ESO: our LoI has been favourably considered and we are invited to submit a proposal for a public spectroscopic survey. Thanks to you all for your contribution during the LoI preparation. And congratulations as well! ESO and the panel advise us to merge with the Milky Way proposal, coordinated by Gerry Gilmore. We will all need to work together towards a very strong proposal and an optimal devised and balanced survey. I'll be back in touch soon asking for input. In the mean time, have a nice weekend.

The evaluation was done by a specially convened panel of six eminent scientists. The 24 letters of intent were carefully examined and discussed in a face-to-face meeting at ESO Garching at the end of January.

We would like to invite you to submit a proposal for a public spectroscopic survey. However, the panel felt that the synergies with the project proposed by Gerry Gilmore (Cambridge) are significant and a merged proposal would be considered very favourably. It is clear that only one proposal can be accepted, and should you submit an independent proposal, it will be judged against the other submission. Please take the comments by the panel into account for your proposal. The specific panel comments for your project reads: In conjunction with Gaia, the spectroscopic study of open clusters in the Milky Way disk is an important task which will produce a dataset with diverse applications and a strong legacy value. In particular, it will allow the star formation history and secular evolution of the main stellar component of our Galaxy to be studied in detail, as well as calibrating many aspects of the theories of stellar and cluster evolution. As a result the panel was very favorably impressed by this proposal. The exploration of the other stellar populations of the Milky Way has been proposed for another public survey (also using FLAMES) which the PSSP is also recommending to submit a full proposal. Splitting the available survey time with FLAMES between the two programmes would give a substantially more complete overview of the stellar populations of the Galaxy than either programme on its own. Yours Faithfully, Bruno. ------------------------------------------------------------------- |
