Destriping Cosmic Microwave Background Polarimeter data
, 2013 Destriping is a well-established technique for removing low-frequency correlated noise from Cosmic Microwave Background (CMB) survey data. In this paper we present a destriping algorithm tailored to data from a polarimeter, i.e.

Evidence for cosmic neutrino background form CMB circular polarization [PDF]
, 2014 The primordial anisotropies of the cosmic microwave background are linearly polarized via Compton-scattering. On the other hand, a primordial degree of circular polarization of the Cosmic Microwave Background is not observationally excluded. In this work,

Constraints on Dark Matter Interactions with Standard Model Particles from Cosmic Microwave Background Spectral Distortions. [PDF]
Physical Review Letters, 2015 We propose a new method to constrain elastic scattering between dark matter (DM) and standard model particles in the early Universe. Direct or indirect thermal coupling of nonrelativistic DM with photons leads to a heat sink for the latter.

Large Scale Cosmic Microwave Background Anisotropies and Dark Energy [PDF]
, 2003 In this note we investigate the effects of perturbations in a dark energy component with a constant equation of state on large scale cosmic microwave background anisotropies. The inclusion of perturbations increases the large scale power.

Perspectives for Cosmological Reionization From Future CMB and Radio Projects
Frontiers in Astronomy and Space Sciences, 2018 In spite of the great recent results from the Planck satellite supporting cosmological reionization scenarios almost compatible with astrophysical models for the evolution of structure, galaxy and star formation, the full understanding of the ...

The lensing and temperature imprints of voids on the cosmic microwave background. [PDF]
, 2016 We have searched for the signature of cosmic voids in the cosmic microwave background (CMB), in both the Planck temperature and lensing-convergence maps; voids should give decrements in both.

Taking the Universe's Temperature with Spectral Distortions of the Cosmic Microwave Background. [PDF]
Physical Review Letters, 2015 The cosmic microwave background (CMB) energy spectrum is a near-perfect blackbody. The standard model of cosmology predicts small spectral distortions to this form, but no such distortion of the sky-averaged CMB spectrum has yet been measured.

The Cosmic Microwave Background and Particle Physics [PDF]
, 1999 In forthcoming years, connections between cosmology and particle physics will be made increasingly important with the advent of a new generation of cosmic microwave background (CMB) experiments. Here, we review a number of these links.

Exploring cosmic origins with CORE: Extragalactic sources in cosmic microwave background maps [PDF]
, 2016 We discuss the potential of a next generation space-borne Cosmic Microwave Background (CMB) experiment for studies of extragalactic sources. Our analysis has particular bearing on the definition of the future space project, CORE, that has been submitted ...
