We present cosmological constraints based on the cosmic microwave background (CMB) lensing potential power spectrum measurement from the recent 500 deg2 SPTpol survey, the most precise CMB lensing measurement from the ground to date. We fit a flat ΛCDM model to the reconstructed lensing power spectrum alone and in addition with other data sets: baryon acoustic oscillations (BAO), as well as primary CMB spectra from Planck and SPTpol. The cosmological constraints based on SPTpol and Planck… 

CMB lensing from Planck PR4 maps

We reconstruct the Cosmic Microwave Background (CMB) lensing potential on the latest Planck CMB PR4 (NPIPE) maps, which include slightly more data than the 2018 PR3 release, and implement quadratic

We investigate the origin of Lambda cold dark matter parameter constraints in weak lensing, with a focus on the Hubble constant. We explain why current cosmic shear data are sensitive to the

Combined analysis of Planck and SPTPol data favors the early dark energy models

We study the implications of the Planck temperature power spectrum at low multipoles, 0ℓ<100, and SPTPol data. We show that this combination predicts consistent lensing-induced smoothing of acoustic

Lensing power spectrum of the cosmic microwave background with deep polarization experiments

Precise reconstruction of the cosmic microwave background lensing potential can be achieved with deep polarization surveys by iteratively removing lensing-induced B modes. We introduce a lensing

Exploring an early dark energy solution to the Hubble tension with Planck and SPTPol data

A promising idea to resolve the long standing Hubble tension is to postulate a new subdominant dark-energy-like component in the pre-recombination Universe which is traditionally termed as the Early

Testing AdS early dark energy with Planck, SPTpol, and LSS data

The Hubble tension might be resolved by injecting a new energy component, called Early Dark Energy (EDE), prior to recombination. An Anti-de Sitter (AdS) phase around recombination can make the
