Doppler peaks in the angular power spectrum of the cosmic microwave background : a fingerprint of topological defects

We present configurations of polarimeters which measure the three Stokes parameters I, Q and U of the Cosmic Microwave Background Radiation with a nearly diagonal error

R. Haïssinski, et al.. About the connection between the C_ℓ power spectrum of the cosmic microwave background and the γ_m Fourier spectrum of rings on the sky.. Concerning

Polarization measure- ments will furnish fresh and independent information on the primordial density perturbations and cosmological parameters, and they offer the exciting potential

While maximum likelihood methods define an estimator to solve the a posteriori density, Gibbs sampling methods for power spectrum estimation [Eriksen et al (2004b)] propose

important, we identify degeneracies between Y p and other cosmological parameters, most notably the baryon abundance, the redshift and optical depth of reionization and the spec-

When the strong (I 100 µ m > 1 Jy) point sources are removed from the ISSA maps, we recover a power spectrum typical of cirrus emission at low spatial frequencies but with still

By analyzing Planck dust polarization maps toward the southern Galactic cap, the part of the sky used for CMB observations from Antartica and Atacama, PXLIV related the

Neverthe- less, there do exist claims of internal inconsistencies in CMB data (Addison et al. 2016), with the parameter shifts we discuss here playing an important role, since
