Planck Precision Lambda CDM Test
Efstathiou contributes to Planck cosmological analysis that tightly constrains the standard Lambda-CDM model and the density of the dark-energy component.

Planck Final Dark Energy Constraints
Efstathiou contributes to Planck's final cosmological parameter analysis, which remains consistent with dark energy behaving as a cosmological constant.
