Proceedings
Overview:
The proceedings of the International Workshop on Astronomical X–Ray Optics will be published on this web-page after acceptance from autor. We will also create textbook. The deadline for submision will be specified soon.
Further information and instructions to authors for the preparation of manuscripts will be provided in due course.
We guarantee publication only of those contributions that have been presented (oral/poster) by the lead author or one of the co-authors during the workshop.
