The Lorentz workshop brought together an international and interdisciplinary community for research on Energetic Processing of Large Interstellar Molecules to overview the state of the art in experimental and theoretical studies on energetic processing of large molecules by ions and photons and address the key questions and strategies to advance our understanding of large molecules in space. Experts were drawn from working Group 2 of the XLIC COST action (CM1204) Energetic Processing of Large Interstellar Molecules and from Theme 3, Interstellar PAHs, of the Dutch Astrochemistry Network (DAN). These experts covered the fields of molecular physics, physical chemistry, and astronomy, including molecular physicists involved in laboratory or quantum chemical studies on the interaction of energetic ions or photons with large molecules and astronomers involved in studies of the origin and evolution of large molecules in space. The program consisted of invited reviews in this highly interdisciplinary field supplemented by contributed talks sketching the depth of on-going research. The program also included ample time for discussion. The workshop was attended by 26 scientists from 10 countries.
The workshop has very successful in defining the key questions for the field and advised strategies to address these (see below). Specifically, the close interaction between the participants facilitated the definition of a number of new joint experimental, theoretical, and observational studies with the aim of understanding energetic processing of large molecules of astrophysical relevance, including polycyclic aromatic hydrocarbons as well as carbon chains, and fullerenes.
Progress in these joint projects will be monitored at a successor meeting on Energetic Processing of Large Molecules (EPoLM-2, April 11-13, 2016). EPoLM-2 will be held in conjunction with the XLIC Stockholm meeting which runs from April 13-15.
