Presentation of the workshop
The COLLEXISM workshop was held in Trébeurden from July 8th to 9th 2024.
The aim of this workshop is to celebrate the successful completion of the ERC COLLEXISM project, which has spanned the last five years. The workshop provides a summary of the project's work and key findings.
ERC COLLEXISM is a multidisciplinary initiative that brings together expertise in quantum chemistry, molecular dynamics, and astrophysical modeling. The project’s primary goal has been to develop new theoretical approaches for studying collisional excitation in reactive systems of astrophysical interest, particularly those involving radicals and ions. A key achievement of COLLEXISM is the combination of statistical and quantum methods to simultaneously address both inelastic and reactive processes. Notably, polyatomic systems have been incorporated into these approaches for the first time.
The collisional data generated throughout the project have been applied to radiative transfer modeling, providing a valuable interpretations of current and future astronomical observations. These results have also led to revisions in astrochemical models.
By the date of the workshop, COLLEXISM had engaged 4 postdocs, 5 PhD students. Overall, the project led to 40 publications, covering over 40 collisional systems, excluding isotopologues and isomers.
During the workshop, F. Lique, A. Godard Palluet, C. T. Bop, F. Tonolo, M. Żółtowski, P. Pirlot Jankowiak and S. Demes presented one study that was
particularly important to them during the ERC COLLEXISM.
Bruno Bêche, professor and Duncan Bossion, assistant professor at the Institute of Physics of Rennes presented their research in oral communication as invited speakers.
