Scientific Rationale

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

    Practical Info: Getting around in Hamburg

    Public Transportation

    The HVV is the public transport operator in Hamburg. It includes subways and busses. You can purchase tickets at a ticket machine at the entrance of every station or directly on the bus. The current fee for using the public transportation without a valid ticket is 60 EUR. The most frequent used ticket options are:

    - One way ticket (Einzelfahrkarte Grossbereich AB): 3,10 EUR
    - Unrestricted day ticket (Tageskarte): 7,60 EUR
    - Restricted day ticket (9 Uhr Tageskarte): 6,20 EUR

    The operation time of the HVV usually is weekdays from approx. 4am to 0.30am and fridays and saturdays the operation continues all day and night.

    StadtRAD Hamburg

    StadtRAD Hamburg is a provider of bicycles in the wider area of Hamburg. The network of stations and the number of bicycles is extensive and provides a quick get around in Hamburg. The easy process of registration can be conducted online or at every station via a terminal. Registration works with a credit or debit card. There is a 5 Euro registration fee which is applied as credit to your account. Every starting 30 minutes of each renting period are free, but starting from the 31st minute, it costs 8 ct/minute. One can return the bike at every station which can be found online or via the terminal at each station.
