Authored annotation: specializes to the concordance cosmological model

Authored explanation

$\Lambda$ CDM applies general relativity to an FLRW background with a cosmological constant, cold dark matter, ordinary matter, radiation, and specified primordial perturbations.

How to interpret this relation type

A more specific theory, model, entity class, or regime is obtained by restricting or extending the scope of a broader framework.
