DES Y1 results: Splitting growth and geometry to test Λ CDM
We analyze Dark Energy Survey (DES) data to constrain a cosmological model where a subset of parameters—focusing on Ω m—are split into versions associated with structure growth (e.g., Ω m grow) and expansion history (e.g., Ω m geo). Once the parameters have been specified for the Λ CDM cosmological model, which includes general relativity as a
