Impact of early dark energy on the Planck SZ cluster sample

Understand

Context.

• One science goal of the upcoming Planck mission is to perform a full-sky cluster survey based on the Sunyaev-Zel'dovich (SZ) effect, which leads to the question of how such a survey would be affected by cosmological models with a different history of structure formation than LCDM.
• One class of these models are early dark energy (EDE) cosmologies, where the dark energy contribution does not vanish at early times.
• Aims.
