The APC laboratory (AstroParticle and Cosmology) is looking for a research CDD (post-doc) to develop data analysis methods for the LISA mission analyzing the different stochastic backgrounds of astrophysical and cosmological origin. He/she will study the scientific performances of the mission when these backgrounds are taken into account.
LISA is the European Space Agency's L3 large mission that will explore the gravitational Universe in the milli-hertz band. It will observe a wide variety of gravitational wave sources such as binary white dwarfs, neutron stars and black holes ranging from a few stellar masses to several tens of millions, as well as gravitational waves emitted in the early Universe. The LISA mission is currently in phase A for a launch planned for 2034. France is responsible for the Distributed Data Processing Center (DDPC), which is currently in the prototyping phase and supports developments in simulation and data analysis. The APC laboratory is one of the main driving laboratories in this activity.
The mission of the post-doc will consist of continuing the developments initiated on methods to evaluate the level of stochastic backgrounds of astrophysical origin from different types of sources and then to characterize the scientific performance of LISA. He/she will have to develop parameter estimation tools for different sources. All these developments will be supported and integrated into the LISA DDPC.
- Continue to develop methods to assess the level of stochastic backgrounds of astrophysical origin.
- Develop and/or improve methods for the analysis of stochastic backgrounds and binary sources.
- Characterize the scientific performances of LISA with the development and exploitation of parameter estimation algorithms based on Bayesian analysis.
- Integrate the codes and tools developed into the LISA Data Processing Center prototype.
- Good knowledge of LISA and LISAPathfinder missions.
- Good knowledge of data analysis methods, particularly Bayesian methods.
- Good knowledge of the astrophysical and cosmological sources that LISA will observe.
- Good knowledge of programming and python language
- Good oral and written English.
- Ability to work in a team.
- Ability to analyze, organize, discipline, autonomy, and communication.
The APC laboratory is managed by several research agencies: CNRS, Université Paris 7 Denis-Diderot, CEA (Commissariat à l'énergie Atomique), and the Paris Observatory. It is located on the campus of the "Grands Moulins" of the University of Paris 7. The laboratory focuses on the field of astroparticle physics, at the interface of the infinitely large and infinitely small, particle physics and astrophysics. It is involved in both ground and space experiments. The successful candidate will join the Gravitation group and the LISA group of the laboratory. It will work closely with the scientific team of the LISA mission. He/she will interact with the French Space Agency (CNES) and the international consortium of the LISA mission.
