Missions

The applicant will carry laboratory astrophysics activities on cosmic dust in the group of Dr. Christine Joblin at Toulouse University / CNRS. He or she will study the reactivity of stardust analogues with molecules using the PIRENEA 2 setup, which is developed in the framework of the NANOCOSMOS project (FP7-ERC-Synergy Grant). PIRENEA 2 combines sources of aggregates and nanograins with a cryogenic environment and several ion trapping techniques, allowing the study of molecular processes under conditions similar to those encountered in interstellar molecular clouds.

Activities

The nanograins of interest will be clusters composed of carbon, silicon/iron/titanium and hydrogen produced with a laser vaporization source. The next step will be to study their reactivity, including at low temperature, with various hydrocarbons CH4, C2H2 et C2H4 and other molecules such as H2O and CO, which can give rise to key reactions in different types of astrophysical environments. The selection of reactions of interest will benefit from the synergy with the studies carried out on the Stardust machine in Madrid.

Skills

We are looking for a candidate with a PhD degree and training in experimental physics and physical chemistry. Experience in mass spectrometry, ion optics and laser spectroscopy is expected. The candidate must demonstrate his/her interest in working in a multidisciplinary research environment at the interface between molecular physics and astrophysics. The candidate must show a strong motivation and have good skills in writing scientific publications.

Work Context

The PIRENEA 2 device is developed within the framework of an interdisciplinary collaboration involving IRAP (UMR 5277) and LCAR (UMR 5589) at the University of Toulouse (Université Paul Sabatier) / CNRS. The Nanocosmos collaboration involves teams from ICMM and IFF at CSIC in Madrid.

Constraints and risks

The experimental work will be carried out on the LCAR-IRSAMC site where the PIRENEA 2 setup is located. PIRENEA 2 is an experimental physics device that operates in the presence of electro-magnetic radiation and lasers.
