Magnetic Fields in Galaxies
Aim of the workshop
The purpose of this workshop is to better understand magnetic fields in galaxies: to define what we think is well-established, and to define how to move forward on those questions which have no satisfactory answer at present. In particular, the workshop aims to bring together and compare observations, numerical simulations and analytical theory on galactic magnetic fields.
The following subjects will be covered by the programme:
1. Magnetic fields in external galaxies
Structure of the Workshop
The format of the workshop will be a mix of prepared contributions from the participants (mostly short ones of about 15 mins), and broad discussions in which several central questions can be debated. Every attempt should be made to discuss the theoretical and observational aspects side-by-side, so that we can try to agree on what is observed, and how the observations can be understood in terms of the theoretical frame-work. Equally important will be to identify where there is no agreement on what is observed, or predicted, or where the interpretation is not clear, or the prediction ambiguous. Finally, discussion may help to identify ways to resolve discrepancies, lack of understanding etc.
We think that the four areas indicated above can be addressed most effectively by defining several questions that we would like answered by the end of the Workshop. Clearly, the questions can be divided into subject areas, but there are so many relationships between the subject areas that we would like to build the Workshop primarily around a set of questions. Below we have listed a few of the more obvious questions, without attempting to be complete. In the next month, we will put together a more detailed programme on the basis of input from the participants.
The large-scale magnetic field
The field and its interaction with the ISM
