Planck intermediate results. LI. Features in the cosmic microwave background temperature power spectrum and shifts in cosmological parameters [PDF]
, 2016 The six parameters of the standard $\Lambda$CDM model have best-fit values derived from the Planck temperature power spectrum that are shifted somewhat from the best-fit values derived from WMAP data.

Cosmic Microwave Background: Past, Future, and Present [PDF]
, 1999 I explain the origin and evolution of anisotropies in the Cosmic Microwave Background (CMB) and argue that upcoming experiments will measure cosmological and fundamental parameters very accurately.

Stringy Signals from Large-Angle Correlations in the Cosmic Microwave Background?
Universe, 2022 We interpret the lack of large-angle temperature correlations and the even-odd parity imbalance observed in the cosmic microwave background (CMB) by COBE, WMAP and Planck satellite missions as a possible stringy signal ultimately stemming from a ...

Generative Models of Multichannel Data from a Single Example—Application to Dust Emission
The Astrophysical Journal, 2023 The quest for primordial B -modes in the cosmic microwave background has emphasized the need for refined models of the Galactic dust foreground. Here we aim at building a realistic statistical model of the multifrequency dust emission from a single ...

Cosmic birefringence fluctuations and cosmic microwave background B-mode polarization
Physics Letters B, 2015 Recently, BICEP2 measurements of the cosmic microwave background (CMB) B-mode polarization has indicated the presence of primordial gravitational waves at degree angular scales, inferring the tensor-to-scalar ratio of r=0.2 and a running scalar spectral ...
