Despite the harsh conditions (extremely low pressure and temperature) prevailing in the interstellar medium (ISM), more than 200 molecules have been detected so far. How these molecules form is often subject to debate, as the interstellar chemistry is substantial different from that occurring in terrestrial laboratories. Nonetheless, astrochemists have built up models which are able to reproduce some of the astronomical observations even though they unable to account for several simple and complex ones. These models rely on the so-called astrochemical networks, namely the networks of reactions supposed to occur in the ISM. Current astrochemical networks count more than 8000 reactions in the gas phase and a similar number on the grains surface. Unfortunately, however, only a small fraction (not more than 15%) of these reactions have been studied in the laboratories or theoretically. Verifying the reliability of all the reactions in the astrochemical networks via dedicated experiments and/or theoretical computations is such a gigantic challenge that is simply impossible. The approach of this thesis is to use artificial intelligence techniques in order to do this job. This will take advantage of the connection with the various experiments and theoretical computations carried out by the members of the ACO team. The goal of the thesis is not only to "clean" the present astrochemical networks as much as possible but also to propose new possible reactions not taken into account at present.
The thesis is part of the ACO network, whose ultimate goal is to reconstruct the early history of the Solar System by comparing presently forming solar-type planetary systems with its small bodies. The comparison will be based on the most advanced astrochemical knowledge, which will be developed by the interdisciplinary ACO team.
The successful applicant must have a Master’s degree in Physics or Astrophysics or Computer Science or similar by the time of enrollment and be highly motivated. Knowledge of relevant program languages and/or previous experience in astrochemistry and modeling will be appreciated.
Excellent undergraduate and Master's degree grades are expected as well as a high level of written and spoken English. Team work ability is essential.
