1. Inscription journée prospective X du 24 septembre 2013
2. 1st WISH Workshop in France - 3 Octobre 2013, IAP Paris
3. Call for nominations for the 2014 MERAC Prizes

1. Inscription journée prospective X du 24 septembre 2013

Dans le cadre de la préparation de son exercice de prospective (2014), le CNES a souhaité que la communauté française entame une réflexion sur l’astronomie X (environ 0.1 keV à 100 keV). Une enquête a été menée auprès de toute la communauté en avril-mai. L’ensemble des résultats seront présentés le 24 septembre au siège du CNES à Paris, à partir de 9h30. La journée sera l’occasion de débats sur les orientations possibles et les grands axes prospectifs.

La journée est ouverte à tous mais les participants sont invités à s’enregistrer pour permettre leur accès au siège du CNES à Paris où se déroulera la réunion (inscription sur ce site web).

Les détails et le programme de la journée sont disponibles ici. Les résultats de l’enquête seront également mis en ligne sur ce site.

2. 1st WISH Workshop in France - 3 Octobre 2013, IAP Paris

1st WISH Workshop in France
October 3, 2013, 10:00 - 17:00
Institut d’Astrophysique de Paris, Salle des séminaires, 98bis Boulevard Arago, 75014 Paris

WISH (Wide-field Infrared Surveyor for High-redshift) is a new space science mission concept whose primary goal is to study the first galaxies in the early universe. WISH will be a Japan-led 1.5m telescope equipped with a 1000 arcmin2 wide-field, Near-IR, 0.2-0.5arcsec FWHM, camera that would fly by 2020 in order to conduct unique ultra-deep and wide-area sky surveys in the wavelength range 1-5 micron. A spectroscopic parallel mode (WISHSpec, Integral-Field Unit) in the same Near-IR range is planned and would be studied in France under the responsibility of LAM. Although the instrument design is still open, with the parallel mode, we could envisage very deep exposure times in spectroscopy over (relatively) wide areas.

Several photometric surveys are planned (1000deg2 to AB=28, 100deg2 to AB=28 and 0.25deg2 to AB=29) that should take 75% of the science telescope lifetime. Spectroscopically, we envision two spectroscopic surveys (10deg2 to 8x10^-16erg/s and 8x10^-17erg/s). They will allow to detect the first galaxies to z 15 (if any) and to physically study the first generation of stars spectroscopically at 3

Beyond the above main science case, WISH would be excessively useful to other themes related to the Programme Nationale Cosmologie et Galaxies (PNCG) and the optimal balance between the major science drivers still needs to be defined. The aim of this workshop is therefore to help defining the science case for WISH and more specifically for the spectrograph WISHSpec by bringing together people interested in this matter. This meeting is planned to be informal with ample time for discussion.

Last but not least, WISH will be crucial because it will provide a way of selecting targets of interest for the JWST and the ELTs. It will also be complementary to other missions like Euclid/WFIRST/SPICA by providing deep data in the 1-5 micron range.

So, we invite you to participate and contribute to this WISH workshop by sending an email to Denis Burgarella as soon as possible. Short talks ( 10 - 15 minutes) are welcomed. The workshop will be divided in several sessions allowing people to present talks related to cosmology, extragalactic studies, stars, planets and Solar system bodies but also to instrumentation to present how they would think/use WISH.

The presentations will be compiled and uploaded on a WISH webpage.

3. Call for nominations for the 2014 MERAC Prizes

Foundation MERAC is a non-profit foundation started in 2012 with headquarters in Switzerland to recognize and support young European astronomers. There are yearly three MERAC Prizes awarded by the EAS. The prizes of EUR 20’000.- are for each of the three categories :

- Theoretical Astrophysics

- Observational Astrophysics

- New Technologies (Instrumental/Computational)

The EAS Council invites EAS members to nominate suitable candidates for the MERAC Prizes of 2014. This being an even year, the three prizes will be Best Doctoral Thesis Prizes. The Prizes will be awarded for the best PhD Theses in Astrophysics for degrees awarded during the period June 2010 — July 2013.

The deadline for nomination is Monday, September 30, 2013 at 16:00 CEST.

Please use the dedicate web interface.
