Future CMB Constraints on Early, Cold, or Stressed Dark Energy
Future CMB Constraints on Early Cold Stressed Dark Energy
2011/1/11
We investigate future constraints on early dark energy (EDE) achievable by the Planck and CMBPol experiments, including cosmic microwave background (CMB) lensing. For the dark energy, we include the p...
The statistics of the curvature quanta generated during a stage of inflationary expansion is used to derive a count response model for the large-scale phonons determining, in the concordance lore, the...
Large-angle correlation anomalies and odd-parity preference in CMB data
cosmic background radiation early universe methods: data analysis meth-ods: statistical
2010/11/9
Angular power spectrum of CMB anisotropy and two point angular point correlation possess some
equivalence. Noting this, we have investigated the association between the WMAP large-angle corre-lation ...
The new generation CMB B-mode polarization experiment: POLARBEAR
new generation CMB B-mode polarization experiment
2010/11/10
We describe the Cosmic Microwave Background (CMB) polarization experiment called Po-larbear. This experiment will use the dedicated Huan Tran Telescope equipped with a powerful 1,200-bolometer array r...
CMB two- and three-point correlation functions from Alfvén waves
CMB two- and three-point correlation functions Alfvén waves
2011/1/10
We study the cosmic microwave background (CMB) temperature fluctuations non-gaussianity due to the vector mode perturbations (Alfv\'en waves) supported by a stochastic cosmological magnetic field. We ...
How to make clean separation of CMB E and B mode from incomplete sky data
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
We have investigated CMB E/B decomposition of incomplete sky data. Noting E and B mode decomposition operators in real space involve differentials of CMB polarization, we point out we may make clean E...
Last scattering, relic gravitons and the circular polarization of the CMB
relic gravitons circular polarization
2010/3/19
The tensor contribution to the $V$-mode polarization induced by a magnetized plasma at last scattering vanishes exactly. Conversely a polarized background of relic gravitons cannot generate a $V$-mode...
