Offer Description

• The Astroparticle and Cosmology Laboratory

The Astroparticle and Cosmology Laboratory (APC) is a leading French research institute affiliated with Université Paris Cité, CNRS/IN2P3, CEA, and the Paris Observatory. It conducts cutting‑edge research in astroparticle physics, cosmology, gravitation, and high‑energy astrophysics, combining theory, data analysis, and participation in major international collaborations.

Structured into five research teams (theory, cosmology, gravitation, high-energy astrophysics and particles), APC fosters cross‑disciplinary exchange and hosts a vibrant scientific community. As part of the IN2P3 Institute of CNRS, APC benefits from scientific coordination and technical infrastructure, including access to national computing resources.

• IRFU/DAp-AIM, CEA Paris‑Saclay

IRFU is the largest fundamental research institute of CEA, in the heart of the Paris‑Saclay University, 40 km south of Paris. It covers major science fields in particle and nuclear physics and astrophysics, with a strong participation in instrumentation. The astrophysics department of IRFU, UMR AIM, is a joint CEA, CNRS, Université Paris‑Cité laboratory. It comprises 200 scientists, engineers, and technicians and covers astrophysics from planetology and stellar formation to high‑energy astrophysics, galaxy dynamics and cosmology. The group as a major implication in CTAO at various levels of the data analysis chain.

Activities

The postdoctoral researcher will be part of a team involved in the data analysis and interpretation of two major very‑high‑energy gamma‑ray observatories: the Large High‑Altitude Air Shower Array (LHAASO) and the Cherenkov Telescope Array Observatory (CTAO). The research project will be focused on the understanding of some extragalactic sources (active galactic nuclei and gamma‑ray bursts) suited to the detailed study of the propagation and interaction of the gamma rays through the Universe, with the objective of characterizing the extragalactic background light and the intergalactic magnetic fields. The postdoctoral researcher will share is working time on both laboratories.

Expected Skills

• Experience in analysis of data of gamma‑ray telescopes
• Knowledge of Python, C++
• Working knowledge of English (B2 / C1)

Obligations and risks

• Working hours: Monday to Friday, between 9 AM to 5 PM
• The post-doc will work 50% of the time at APC and 50% of the time at IRFU/Dap‑AIM. Partial remote work is possible.
• The work may require traveling abroad on occasion.
• Training and experience required
