High-Energy Astrophysicist H/F - CEA

Le CEA est un acteur majeur de la recherche, au service des citoyens, de l'économie et de l'Etat.

Il apporte des solutions concrètes à leurs besoins dans quatre domaines principaux : transition énergétique, transition numérique, technologies pour la médecine du futur, défense et sécurité sur un socle de recherche fondamentale. Le CEA s'engage depuis plus de 75 ans au service de la souveraineté scientifique, technologique et industrielle de la France et de l'Europe pour un présent et un avenir mieux maîtrisés et plus sûrs.

Implanté au coeur des territoires équipés de très grandes infrastructures de recherche, le CEA dispose d'un large éventail de partenaires académiques et industriels en France, en Europe et à l'international.

Les 20 000 collaboratrices et collaborateurs du CEA partagent trois valeurs fondamentales :

- La conscience des responsabilités
- La coopération
- La curiosité

The SVOM satellite mission (Space based Variable astronomical Object Monitor) was launched in June 2024 and is now in its nominal scientific operations phase.

SVOM is dedicated to studying the transient sky, with a particular focus on cosmic gamma-ray bursts-powerful explosions resulting from the gravitational collapse of massive stars or the coalescence of compact objects (neutron stars, black holes). SVOM's payload covers optical, X-ray, and gamma-ray domains to enable multi-wavelength studies of these variable and transient phenomena. The SVOM mission is complemented by a ground segment for science operations, which includes a dedicated suite of robotic telescopes. For more information about SVOM, visit www.svom.eu.

As part of the SVOM mission, the DAp is recruiting a postdoctoral researcher for data analysis and physical interpretation of cosmic gamma-ray bursts. As a bilateral Franco-Chinese mission, SVOM benefits from strong involvement of the DAp in its scientific operations.

The postdoctoral researcher will join the DAp's SVOM scientific team and collaborate broadly with the international scientific community involved in the mission. SVOM data are accessible to all collaboration members, and the work will focus primarily on data analysis and, in particular, on the physical interpretation of the prompt and afterglow phases of bursts detected by SVOM and partner telescopes.

The postdoctoral researcher will also participate in the mission's science operation activities, notably by acting as a "Burst Advocate" to help coordinate and optimize real-time observational follow-up for bursts detected by SVOM

Interested candidates are invited to submit a CV along with a publication list, a cover letter, two letters of recommendation, and the PhD reviewers' reports.

The earliest start date is February 2027, but the position will be open until filled.
