The detection of the B-mode polarization of the cosmic microwave background (CMB) by the BICEP2 experiment implies that the tensor-to-scalar ratio $r$ should be involved in the base standard cosmology. In this paper, we extend the $\Lambda$CDM+$r$+neutrino/dark radiation models by replacing the cosmological constant with the dynamical dark energy with constant $w$. Four neutrino plus dark energy models are considered, i.e., the $w$CDM+$r+\sum m_\nu$, $w$CDM+r + $N_{\rm eff}$, $w$CDM+r + $\sum…

Impacts of dark energy on weighing neutrinos after Planck 2015
We investigate how dark energy properties impact the cosmological limits on the total mass of active neutrinos. We consider two typical, simple dark energy models (that have only one more additional
Constraints on inflation revisited: an analysis including the latest local measurement of the Hubble constant
We revisit the constraints on inflation models by using the current cosmological observations involving the latest local measurement of the Hubble constant ($$H_{0} = 73.00\pm 1.75$$H0=73.00±1.75 km
Impact of the latest measurement of Hubble constant on constraining inflation models
We investigate how the constraint results of inflation models are affected by considering the latest local measurement of $H_0$ in the global fit. We use the observational data, including the Planck
Neutrinos in the holographic dark energy model: constraints from latest measurements of expansion history and growth of structure
The model of holographic dark energy (HDE) with massive neutrinos and/or dark radiation is investigated in detail. The background and perturbation evolutions in the HDE model are calculated. We
