Nonparametric inference for the Cosmic Microwave Background [PDF]

Statistical Science, 2004
The Cosmic Microwave Background (CMB), which permeates the entire Universe, is the radiation left over from just 380,000 years after the Big Bang. On very large scales, the CMB radiation field is smooth and isotropic, but the existence of structure in the Universe - stars, galaxies, clusters of galaxies - suggests that the field should fluctuate on ...

Cosmic microwave background fluctuations

, 2003
Several experiments have recently detected very low contrast, sub-horizon scale structures in the Cosmic Microwave Background (CMB). In the current cosmological model, these structures result from acoustic oscillations of the primeval plasma at ...

The intrinsic B-mode polarisation of the cosmic microwave background [PDF]

, 2014
. We estimate the B-polarisation induced in the Cosmic Microwave Background by the non-linear evolution of density perturbations. Using the second-order Boltzmann code SONG, our analysis incorporates, for the first time, all physical effects at ...

Cosmic microwave background images [PDF]

IEEE Signal Processing Magazine, 2010
We aim to present a tutorial on the detection, parameter estimation and statistical analysis of compact sources (far galaxies, galaxy clusters and Galactic dense emission regions) in cosmic microwave background observations. The topic is of great relevance for current and future cosmic microwave background missions because the presence of compact ...

Cosmic microwave background theory. [PDF]

Proc Natl Acad Sci U S A, 1998
A long-standing goal of theorists has been to constrain cosmological parameters that define the structure formation theory from cosmic microwave background (CMB) anisotropy experiments and large-scale structure (LSS) observations. The status and future promise of this enterprise is described.

Evolution of the cosmic microwave background [PDF]

Physical Review D, 2007
We discuss the time dependence and future of the Cosmic Microwave Background (CMB) in the context of the standard cosmological model, in which we are now entering a state of endless accelerated expansion. The mean temperature will simply decrease until it reaches the effective temperature of the de Sitter vacuum, while the dipole will oscillate as the ...

Observation of Cosmic Microwave Background Polarization with BICEP [PDF]

, 2009
Background Imaging of Cosmic Extragalactic Polarization (BICEP) is a bolometric polarimeter that has been optimized to target the B-mode of the cosmic microwave background (CMB) polarization at degree angular scales, which is a sensitive probe of the ...

CMB anomalies and the effects of local features of the inflaton potential

European Physical Journal C: Particles and Fields, 2017
Recent analysis of the WMAP and Planck data have shown the presence of a dip and a bump in the spectrum of primordial perturbations at the scales $$k=0.002$$ k = 0.002 Mpc $${}^{-1}$$ - 1 and $$k=0.0035$$ k = 0.0035 Mpc $${}^{-1}$$ - 1 , respectively. We
