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 cœur 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 :

Within the Fundamental Research Division (DRF), the Research Institute on the Fundamental Laws of the Universe (IRFU) conducts research to study the fundamental interactions of physics and develops the associated experimental instruments and equipment. Nearly 1,000 physicists, engineers, and technicians are involved daily in international research projects in particle physics, astrophysics, and nuclear physics across platforms as varied as particle accelerators, scientific satellites, and ground-based telescopes.
The Astrophysics Department's mission is to conduct research in astrophysics and to ensure, in liaison with space agencies and ground-based observatories, the project management of space instruments as well as the development of data analysis centers.
It operates in the fields of cosmology, the structure of the universe, the formation and evolution of stars and planets and their interactions, high-energy cosmic phenomena, and astrophysical plasmas. It analyzes experimental data, develops theoretical models and numerical simulations, and produces scientific publications.
It develops and implements instrumental technologies as well as methods for signal processing, numerical simulation, and data analysis in connection with space missions and ground-based observatories across multi-wavelength domains for space astrophysics applications.
It has technological infrastructures and facilities to carry out its technological research, achievements, and their characterization.

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.
High-energy astrophysicist with preferred expertise in one or more of the following fields:
Cosmic Gamma-Ray Bursts: scientific analysis and physical properties
Data reduction and analysis from space missions in high-energy astrophysics
Optical and infrared photometry of transient sources
Study of the transient sky and multi-messenger phenomena

The CEA is the French Alternative Energies and Atomic Energy Commission ("Commissariat à l'énergie atomique et aux énergies alternatives"). It is a public body established in October 1945 by General de Gaulle. A leader in research, development and innovation, the CEA mission statement has two main objectives: To become the leading technological research organization in Europe and to ensure that the nuclear deterrent remains effective in the future.
The CEA is active in four main areas: low-carbon energies, defense and security, information technologies and health technologies. In each of these fields, the CEA maintains a cross-disciplinary culture of engineers and researchers, building on the synergies between fundamental and technological research.
The civilian programs of the CEA received 49% of their funding from the French government, and 30% from external sources (partner companies and the European Union).
The CEA had a budget of 4,3 billion euros.
The CEA is based in ten research centers in France, each specializing in specific fields. The laboratories are located in the Paris region, the Rhône-Alpes, the Rhône valley, the Provence-Alpes-Côte d'Azur region, Aquitaine, Central France and Burgundy. The CEA benefits from the strong regional identities of these laboratories and the partnerships forged with other research centers, local authorities and universities.
