Missions

We propose a 2-year postdoctoral contract at Paris Observatory (France) to work on the physics of flares observed at very high energies in active galactic nuclei (AGN). The objective is to test CTA's ability to distinguish between different scenarios of particle acceleration and emission and to optimize the observing strategy of the Cherenkov Telescope Array (CTA) and the multi-wavelength coverage needed to achieve these objectives. The candidate will have access to the AGN emission modeling codes developed in the team.

The candidate will participate in the preparation of the CTA Science Data Challenge (SDC) by being involved in the development of the temporal aspects of gammapy. Gammapy is an open-source software written in Python, developed in an open way, for gamma-ray astronomy and based on Numpy, Scipy and Astropy. It is used as the base library for CTA's scientific analysis tools. It is already widely used for the analysis of scientific data from existing gamma-ray instruments, such as H.E.S.S. (High Energy Stereoscopic System).

The candidate will be involved in the gammapy development team and should become a regular contributor. He/she will work on one or more of the following aspects: code development and testing, scientific validation, documentation and/or devops. This involves regular participation in virtual developer meetings and in-person coding sprints. Participation in software release is also possible through tutorials, hands-on sessions and user support.

Candidates should hold a PhD in astrophysics and have a good knowledge of high energy astrophysics. Ideally, candidates should have experience with high energy data and be familiar with the astrophysics ecosystem. Experience with software development via GitHub or GitLab is beneficial.

Work Context

The Laboratory Universe and Theories (LUTH) is a joint research unit (UMR 8102) of the CNRS, the Observatoire de Paris and the Université Paris Cité and has its premises in the superb park of the Château de Meudon. The laboratory gathers about fifty people. The scientific activity of the laboratory is mainly focused on the theoretical study of compact objects and on their modeling, including that of very high energy plasmas (GeV - TeV). A part of the activities also concerns the data processing of high energy observations. The LUTH will offer all the necessary means (office, workstation, scientific environment, travel budget) to carry out this work within the High Energy Phenomena team.

Constraints and risks

Travel: short trips are to be expected in France and abroad.
