In the ALMA era a noteworthy effort to provide state-of-the-art chemical models that allow to interpret the data is indispensable. The chemistry exerts its influence on the environment dominating the cooling of gas in dense regions and also controlling the ionization balance, thereby affecting the coupling of magnetic fields to the gas. It is then fundamental to include chemistry and the related microphysics in computational studies aimed at understanding and probing the physical conditions of the different environments.
However, this requires detailed information and knowledge of the basic processes which are obtained from laboratory measurements and theoretical studies of chemical reactions in gas phase, and the study and the characterization of the surface of solid materials where molecules could form.
On the other hand, to include a chemical network, and all the tightly connected physical processes in hydrodynamcal simulations, together with the wide range of involved spatial and temporal scales in astrophysics, leads to a computationally expensive problem. We therefore aim for the development and maintenance of appropriate and well optimized modelling tools that can be employed to study different astrophysical problems.
It is then important to provide a platform connecting the different experts to stimulate an exchange of ideas, and to work towards a coherent understanding of chemical modelling in astrophysics.
This workshop aims at astrophysicists who develop tools and/or employ chemistry and microphysics in hydrodynamical simulations of the interstellar medium, and experts on the calculations and measurements of rates for chemical processes relevant in astrophysics, both in the gas phase as well as on dust.
The workshop will cover the following topics:
- Gas/Dust phase processes: theory and experiments
- Computational Astrochemistry: Numerical Codes and Databases
- Chemistry/Microphysics in Hydrodynamical Simulations
- Modelling Observations
