Improved constraints on cosmic birefringence from the WMAP and Planck cosmic microwave background polarization data [PDF]

Physical Review D, 2022
The observed pattern of linear polarization of the cosmic microwave background (CMB) photons is a sensitive probe of physics violating parity symmetry under inversion of spatial coordinates. A new parity-violating interaction might have rotated the plane

Cross-Correlating Astrophysical and Cosmological Gravitational Wave Backgrounds with the Cosmic Microwave Background. [PDF]

Physical Review Letters, 2021
General relativity provides us with an extremely powerful tool to extract at the same time astrophysical and cosmological information from the stochastic gravitational-wave backgrounds (SGWBs): the cross-correlation with other cosmological tracers, since

Real-space entanglement in the Cosmic Microwave Background [PDF]

Journal of Cosmology and Astroparticle Physics, 2021
We compute the entanglement entropy, mutual information and quantum discord of the Cosmic Microwave Background (CMB) fluctuations in real space. To that end, we first show that measurements of these fluctuations at two distinct spatial locations can be ...

Fast emulation of anisotropies induced in the cosmic microwave background by cosmic strings

The Open Journal of Astrophysics, 2023
Cosmic strings are linear topological defects that may have been produced during symmetry-breaking phase transitions in the very early Universe. In an expanding Universe the existence of causally separate regions prevents such symmetries from being ...

Constraints on primordial gravitational waves from the cosmic microwave background [PDF]

Journal of Cosmology and Astroparticle Physics, 2020
Searches for primordial gravitational waves have resulted in constraints in a large frequency range from a variety of sources. The standard Cosmic Microwave Background (CMB) technique is to parameterise the tensor power spectrum in terms of the tensor-to-

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 ...
