If they are published on Dengeki magazines, then they're most likely official. Whether or not they are canon is a different question.

The オ in アルオヴヘイム threw me off for a moment there. Was wondering where the word begins and end in Aruovuheimu until I checked the picture :D

Anyway, is there any chance that you could photograph/scan the manga? I'd be interested in seeing what are the stories about.
