Job Description summary

Postdoctoral researcher position at Observatoire de la Côte d’Azur (Lagrange) on the calibration of the extragalactic distance scale: The Baade-Wesselink distance of the Cepheids of the Local Group

We advertise a postdoctoral research position to work on improving the calibration of the extragalactic distance scale within the framework of the ANR Grant Unlockpfactor.

The researcher will revisit the Baade-Wesselink method of distance determination of Cepheids by building a tomographic view of their atmosphere using high spectral resolution observations and stellar atmosphere models. The principal objective is to improve the robustness of the BW distance of Cepheids.

This position is funded for two years, with a possible extension of one year, to start the 1st October 2025. The successful applicant will join the Lagrange laboratory, located in Nice.

A PhD in Astrophysics is required at the time of the contract signature. The ideal candidate should be familiar with the analysis of different types of observational data sets in particular spectroscopy. Previous experience with variable stars or stellar atmosphere modeling is desirable. Skills in programming (python) are also required.

The applicants are invited to send via email a cover letter, a curriculum vitae, a brief statement of research interests (maximum 4 pages) with links to recent publications, and two letters of reference to Prof. Nicolas Nardetto.The applications should ideally be received by 15th of June 2025. After this date, the applications will be considered until the position is filled.
