The EU Network Theoretical Foundations of Sources of Gravitational Wave Astronomy is at the beginning of its second year, and it is time to summarize the most interesting results obtained by the collaboration. The goal of this first issue of the Newsletters is ``to break the ice", briefly resuming the results of the different groups, and to provide the bibliography for those who may be interested in more details.

This is only the starting point: I hope very much that the Newsletters will be used in the future not only as a mean to inform about one's group activity, but also to discuss, and exchange ideas. I think it may also be useful to have a release of the Newsletters after the meetings we periodically organize, with reports on the highliths emerged from the discussions, and written version of the talks presented by students and postdocs.

In addition, I strongly encourage people, especially young people, whose scientific training is the main purpose of this collaboration, to write short reports on the results they obtain, even if they are at a preliminary stage: this will certainly make our collaboration more stimulating and fruitful.
