Return of Harrison-Zeldovich spectrum in light of recent cosmological tensions

Jun-Qian Jiang, Gen Ye, Yun-Song Piao

The spectral index $n_{s}$ of scalar perturbation is the significant initial condition set by inflation theory for our observable Universe. According to Planck results, current const…

Towards hybrid inflation with $n_{s} = 1$ in light of Hubble tension and primordial gravitational waves

Gen Ye, Jun-Qian Jiang, Yun-Song Piao

Recently, it has been found that complete resolution of the Hubble tension might point to a scale-invariant Harrison-Zeldovich spectrum of primordial scalar perturbation, i.e. $n_s…

Towards early dark energy and $n_{s}$ =1 with Planck, ACT and SPT

Jun-Qian Jiang, Yun-Song Piao

We investigate the constraints on early dark energy (EDE) by combining the most recent CMB observations available, ACT DR4, SPT-3G, and Planck2018 ( $ℓ_{TT,max} = 1000$ ) data.…
