The Cosmic Microwave Background [PDF]
Living Reviews in Relativity, 1998 We present a brief review of current theory and observations of the cosmic microwave background (CMB). New predictions for cosmological defect theories and an overview of the inflationary theory are discussed.

New physics from the polarized light of the cosmic microwave background [PDF]
Nature Reviews Physics, 2022 The current cosmological model requires new physics beyond the standard model of elementary particles and fields, such as dark matter and dark energy. Their nature is unknown and so is that of the initial fluctuations in the early Universe that led to ...

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 ...
