Galaxy clustering, CMB and supernova data constraints on ϕ CDM model with massive neutrinos
Physics Letters B
We investigate a scalar field dark energy model (i.e., ϕCDM model) with massive neutrinos, where the scalar field possesses an inverse power-law potential, i.e., V(ϕ)∝ϕ^-α (α>0). We find that the sum of neutrino masses Σ m_ν has significant impacts on the CMB temperature power spectrum and on the matter power spectrum. In addition, the parameter α also has slight impacts on the spectra. A joint sample, including CMB data from Planck 2013 and WMAP9, galaxy clustering data from WiggleZ and BOSSdoi:10.1016/j.physletb.2015.11.022 fatcat:dubimp5d4rbjdl3kkl42bxgpwi
