About 200 years from now, a human scientific expedition, lead by a international coalition of Earth nations, is sent to an alien moon around a habitable planet, light years from earth. Like it's parent planet, the moon has a stable atmosphere and is mostly habitable but with extreme temperatures that vary during it's seasons. The explorers arrived through a wormhole discovered near Pluto orbit, which is discovered to be the cause of massive, gravitational anomales in the kuiper belt in Sol. (As a note, a small colony already exists on the parent world governed by this international organization which is a next generation UN). After spending some time surveying the moon, this team discovers these alien devices.
At first the devices appear to be large rocky formations that don't particularly catch anyone's eye.
Subsequent scans reveal radiation — a lot of radiation. Across nearly the entire EM spectrum.
The radiation is so strong that protective suits are necessary to approach them.
The shipboard science team realizes that these "pillars" are nothing like anything humanity has seen before, and so the cavalry is called in. Through the course of my story, the cavalry discoveres many things about the pillars, but the important discoveries are:
The pillars are large AI-controlled emitters that are generating a nearby wormhole. (The same wormhole the initial explorers came through.)
The devices are powered by antimatter reactors deep within a nearby cave network.
My Question: I have little idea what types of people would be called in to study these strange alien devices. The ship's science team doesn't know what they're dealing with, so who would be called in first? Once the discoveries start piling up, what specialists would be called in second?
