I've read the guide but din't find any mention about spikes. They seem to be very useful, but I can't find any official mention about them.

What do you think? are they official?

Spikes are typically done in order to clarify scope, or to assess the technical feasibility of items on the Product Backlog. This means that they aren't so much a development & delivery activity as they are a tool for backlog refinement. Although spikes aren't mentioned in the Guide, backlog refinement is.

You're right, it makes sense.

I cannot speak to OFFICIAL but in the teams I have been SM for they are in the backlog and sprint, and they are sized. I encourage sizing because they impact velocity/capacity of the team in the sprint. I also like to see the team as a whole know what is being worked.

User Stories are not mentioned in the Scrum Guide as well.
What else do User Stories and Spikes have in common? They both inherit from Product Backlog Item.

No they're not part of Scrum because not every Scrum team use story points and velocity. Some of the best teams I've work with do not estimate.
