    1. Appel ESA \u00abM8\/F3\u00bb pour deux nouvelles missions scientifiques<\/h3>\n\n\n\n

    L\u2019ESA vient d\u2019ouvrir un appel \u00ab M8\/F3 \u00bb pour deux nouvelles missions scientifiques, une mission de type M (Moyenne), et une mission de type F (Fast) (voir ici : https:\/\/www.cosmos.esa.int\/web\/call-for-missions-2025<\/a> ).<\/p>\n\n\n\n

    Le CNES soutiendra et endossera les contributions fran\u00e7aises aux propositions soumises en fonction de leur ad\u00e9quation avec les priorit\u00e9s identifi\u00e9es par le CERES notamment au s\u00e9minaire de prospective, et apr\u00e8s analyse des ressources impliqu\u00e9es. Une concertation avec les directions des laboratoires concern\u00e9s ainsi qu\u2019avec leurs principales tutelles sera \u00e9galement men\u00e9e.<\/p>\n\n\n\n

    Les \u00e9quipes souhaitant participer \u00e0 une proposition de mission M ou F doivent se manifester aupr\u00e8s du th\u00e9maticien concern\u00e9 du CNES. La liste des th\u00e9maticiens est rappel\u00e9e ci-dessous.<\/p>\n\n\n\n

    2. 6th Announcement of Opportunity for the CHEOPS Guest Observers Programme<\/h3>\n\n\n\n

    We are pleased to announce that the 6th CHEOPS Guest Observers Announcement of Opportunity is now open. Please find attached the letter from the ESA Director of Science.<\/p>\n\n\n\n

    Key Dates: The AO-6 Call is now open and is foreseen to close on the 8 May 2025 (12:00 CEST).<\/p>\n\n\n\n

    Observing Cycle: The selected proposals will be part of the observing cycle from 1 October 2025 to 30 September 2026. This period marks the last year of the first mission extension of CHEOPS.<\/p>\n\n\n\n

    Scientific Opportunities: CHEOPS provides observers with access to space-based pointed ultra-high precision photometry. Research areas include the observations of exoplanet transits, eclipses, occultations, and phase curves. Furthermore, the scientific scope may extend to any time-domain phenomena including, but not limited to, variable stars, super-nova remnants or any other astronomical transient phenomena.<\/p>\n\n\n\n

    Collaborative Synergies: The timely overlap of several space- and ground-based missions may provide exciting opportunities for synergies with NASA\/ESA\/CSA JWST, NASA\/ESA HST, NASA TESS, ESO ground-based facilities, and more.<\/p>\n\n\n\n

    Scope: The AO-6 and the DP calls are open to the worldwide scientific community, regardless of nationality or institutional affiliation. Undergraduate and PhD students are eligible if it is guaranteed that their supervisor can provide sufficient guidance throughout the proposal. Proposers may request as much time as scientifically needed in a single proposal. Large observing programmes which will produce high-value datasets are encouraged.<\/p>\n\n\n\n

    Modern and user friendly:<\/p>\n\n\n\n

    More targets: only 50 GTO reserved targets, with all the rest being open to the entire community
    More time: up to 30% science observing time (around 1500 orbits) dedicated to the GO Programme
    Double-anonymous peer-review of proposals
    Zero-installation tools: cloud-based visibility and ETC web tools
    Community contributions of many useful tools<\/p>\n\n\n\n

    Live hands-on tutorials: We foresee to run hands-on tutorials on March and April 2025 at various time-zones to guide you through the proposal preparation and submission process and answer all your questions. Please register at the link below if you would like to attend or watch the recordings:<\/p>\n\n\n\n

    It aims to bring together communities interested in galaxy formation and cosmic reionization processes, from theory to multi-wavelength observation, including modeling and numerical simulations. The school will foster exchanges between researchers using very different approaches. Seminars proposed by participants completement the program, and PhD students, as part of their training, are invited to submit a short presentation or poster.

    Titre :<\/strong> Le Cherenkov Telescope Array Observatory et le ciel aux \u00e9nergies extr\u00eames<\/p>\n\n\n\n

    R\u00e9sum\u00e9 : <\/strong>Les rayons gamma de tr\u00e8s haute \u00e9nergie, dans le domaine des TeV, r\u00e9v\u00e8lent les objets et les processus les plus spectaculaires de l\u2019Univers. Ils tracent l\u2019acc\u00e9l\u00e9ration de particules dans des sources galactiques, telles que les restes de supernovae, les microquasars ou les n\u00e9buleuses de vent de pulsars, ainsi que dans des sources extragalactiques comme les blazars, les galaxies \u00e0 flamb\u00e9e d\u2019\u00e9toiles ou les sursauts gamma.<\/p>\n\n\n\n

    Les t\u00e9lescopes Cherenkov se sont impos\u00e9s comme des instruments de choix pour observer ce ciel extr\u00eame avec une sensibilit\u00e9 et une r\u00e9solution in\u00e9gal\u00e9es.
    Le Cherenkov Telescope Array Observatory (CTAO) sera le premier observatoire de ce domaine \u00e0 \u00eatre ouvert \u00e0 la communaut\u00e9 et install\u00e9 sur les deux h\u00e9misph\u00e8res, promettant des avanc\u00e9es significatives par rapport aux r\u00e9seaux actuels.<\/p>\n\n\n\n

    Andreas Zech pr\u00e9sentera un bref \u00e9tat des lieux de nos recherches sur les tr\u00e8s hautes \u00e9nergies, avant de me focaliser sur l\u2019\u00e9tat actuel du projet CTAO dans le cadre de notre implication \u00e0 l\u2019Observatoire de Paris.<\/p>\n\n\n\n

    La pr\u00e9sentation durera 40 minutes et sera suivie d’une plage de 15 minutes d\u00e9di\u00e9es aux questions.
