TheNephew,
What the OP refers to are the new minor Radical factions mentionned in the latest
Dark Heresy supplement:
The Radical's Handbook.
These "new" factions are:
- The Libricar (zealots who aim to maintain the Imperium's status quo at any price since they believe the Imperium is "as it is" because that's how the Emperor wanted it. Amalathian extremists.)
- The Ocularians (who seek knowledge of future events by any means...)
- The Oblationists (who knowingly sacrifice their moral purity and use the warp against itself because they believe it to be the only way to fulfill their duty to the Emperor. Also, think no one but them should use Chaos...)
- The Phaenonites (who think only mastery of the Warp --via technology in particular-- will save humanity from all its enemies. Xanthite splinter.)

suliman,
To answer your questions:
No, there is no "signature equipment" mentionned in the entries for these factions.
I haven't used them yet (a bit too early after the release for that, just got my copy of the book last week!)
And, to answer your PS: the book mentions Aetheromancy as one of the methods of divination used by Ocularians, a method which is proscribed outside of the ranks of the Astropathica and
Navis Nobilite... Hence, depending if what you mean by "warp prophet" is what I think you do (that an Ocularian Inquisitor could use a Navigator as a sort of oracle), yes it's possible.

I feel like mentionning however that your thread title is a bit misleading... "Minor Radicals" is quite different in meaning from "Minor Radical Factions" IMO.
The later denomination refers to radical philosophies which have fewer followers than the more famous ones. While the formulation you used makes me think more of Inquisitors who are only "borderline" radicals, not really embracing a radical philosophy but nevertheless using radical means from time to time (because its a necessary evil to achieve a specific goal. For example: banishing a daemon with the only thing able to do it, a possessed weapon, before destroying that weapon itself) or using only the less dangerous tools of a radical's arsenal (like, say, xenos weapons not using Warp-based technology)...
BTW, the book also has a chapter on "Radical Minoris", radical factions which have very few followers (maybe even only one) and thus haven't (yet?) been named (or may have been but their name isn't widely known)... These evidently must be differenciated from the other two mentionned above, so we have to be careful in the terminology we use!
In other words: Minor Radical Factions ≠ Radical Minoris ≠ minor Radicals
