Publications

Please see the ADS for a complete list including links to data and pre-print versions.

Furthermore my undergraduate thesis (Diplomarbeit) and the doctoral thesis (Dissertation) are available; their content is also contained in my earliest refereed articles.

Published books

I collaborate on a project on Roman warships with historians. In this field, articles are less common than in astronomy and the results of these studies are published as books.

• Projekt Römerschiff: Nachbau und Erprobung für die Ausstellung ’2000 Jahre Varusschlacht’
  Ch. Schäfer, R. Aßkamp (Ed.), H. M. Günther et al., Hamburg, 2008, ISBN 978-3-7822-0977-9 (a book on a reconstructed roman warship, I worked on the technical characterization of the sailing performance, in German)

• Lusoria - Ein Römerschiff im Experiment: Rekonstruktion - Tests - Ergebnisse
  Ch. Schäfer, H. M. Günther & A. C. Wawrzyn, Hamburg, 2008, ISBN 978-3-7822-0976-2 (similar to the above for a different type of vessel)

• Lusoria Rhenana, ein römisches Schiff am Rhein: neue Forschungen zu einem spätantiken Schiffstyp Fritz Brechtel, Christoph Schäfer, Gerrit Wagener (Hrsg.) - I wrote the chapter on data analysis, similar to the above, in German.
