Postdoctoral position on the nature and influence of X-ray sources in star-forming galaxies

AIM announces a postdoctoral position on star-forming galaxies in the framework of the French-Swiss collaborative project "speXion" co-funded by the ANR and SNSF.

The overall goal of speXion is to perform a coherent study of extremely metal-deficient galaxies (XMDs) in order to understand the radiation field dominating these galaxies up to X-rays, to characterize the nature, influence of energetic sources and the associated feedback processes, and to understand the contribution of XMDs to cosmic reionization. The collaboration will use multi-wavelength observations as well as state-of-the-art spectral modeling tools. 

The associated post-doctoral positions concern:

• ANR/AIM post-doctoral project (coordinated by Dr. V. Lebouteiller): design a method to infer the intrinsic EUV-to-X-ray spectrum of XMDs from signatures in the interstellar medium (in particular optical and infrared emission lines and UV absorption). 
• ANR/IAP post-doctoral project (coordinated by Dr. H. Atek; see https://emploi.cnrs.fr/Offres/CDD/UMR7095-HAKATE-002/Default.aspx): confront spectral model predictions with a set of LyC observations to establish a robust method able to predict the escape fraction of ionizing photons in star-forming galaxies and their contribution to cosmic reionization.
• SNSF/Geneva post-doctoral project (coordinated by Prof. Daniel Schaerer; see https://aas.org/jobregister/ad/8b56239f): construct a multi-wavelength reference sample at low- and intermediate redshift, analyze and interpret interstellar medium signatures of these galaxies through empirical diagnostics and intricate models.

AIM is a laboratory associated with the Department of Astrophysics (DAp) at CEA, Saclay, located 30 kms / 40 mins from Paris downtown. AIM offers a dynamic environment, with about 200 researchers contributing to many fields of astrophysics from cosmology to transient phenomena and exoplanetary systems. The AIM speXion post-doctorate is expected to be familiar with X-ray observations and data analysis of X-ray binaries and/or active galactic nuclei, and to have general knowledge of probabilistic methods. Knowledge about the interstellar medium or the interplay between compact objects and the ISM is welcome though not mandatory. Informal inquiries about the position are welcome.
