Keyboard graph navigation: press N for concepts or E for relations; use arrow keys, Home, and End to move; Enter selects; Shift plus Enter selects and centers; plus and minus zoom; zero fits; Escape clears the selection. Use the visible viewport buttons as alternatives to dragging, wheel, and pinch gestures.
Select a concept
Select any concept, construction junction, or annotated relation by pointer, touch, search, or keyboard.
Construction junctions are diamonds. They show where multiple structures must coexist on the same carrier and satisfy compatibility conditions.
Move selected concept
Single-pointer and keyboard alternatives to dragging. Each activation moves the selected concept one step.

supplies ionizing photons
Authored explanation
When photon energy exceeds an applicable ionization threshold and the transition matrix element is nonzero, electromagnetic radiation can eject a bound electron from an atom or ion.
How to interpret this relation type
The source field, particle, charge, current, or interaction couples to, acts on, binds, forms, or stabilizes the target in the stated regime. The edge label and detail must identify the exact coupling, interaction, or binding claim and its qualifications.

Authored annotation
photon-induced ionization
Authored explanation
Photoionization is the subclass of atomic ionization driven by photon absorption, distinguished from collisional, field, or other ionization mechanisms.
How to interpret this relation type
The target is a member or subtype of the broader source class.
