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.

Cosmic birefringence fluctuations and cosmic microwave background B-mode polarization
Physics Letters B, 2015 Recently, BICEP2 measurements of the cosmic microwave background (CMB) B-mode polarization has indicated the presence of primordial gravitational waves at degree angular scales, inferring the tensor-to-scalar ratio of r=0.2 and a running scalar spectral ...

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 ...

Balloon-borne Cosmic Microwave Background experiments [PDF]
EPJ Web of Conferences, 2019 Stratospheric balloon experiments play a unique role in current Cosmic Microwave Background (CMB) studies. CMB research has entered a precision phase, harvesting the detailed properties of its anisotropy, polarization and spectrum, at incredible ...

The Boltzmann equation and Cosmic Microwave Background
Revista de Investigación de Física, 2023 Observations on the anisotropies of the Cosmic Microwave Background (CMB) have become a fundamental tool in Cosmology. We present a brief description of the mformalism necessary to understand the evolution of the anisotropies, and how their power ...

Microwaves Are Everywhere
IEEE Journal of Microwaves, 2021 This article is the first in a continuing series of general interest papers on the applications of microwaves in areas of science and technology that might not be evident to the casual observer.

Frequency–Redshift Relation of the Cosmic Microwave Background
Astronomy, 2023 We point out that a modified temperature–redshift relation (T-z relation) of the cosmic microwave background (CMB) cannot be deduced by any observational method that appeals to an a priori thermalisation to the CMB temperature T of the excited states in ...

Photonic Integrated Circuits for Microwave Astronomy
Inventions, 2023 One of the main objectives of cosmology is the measurement of the Cosmic Microwave Background (CMB) polarization and, in particular, the so-called B-modes, which could demonstrate the existence of the primordial gravitational waves generated at the early

Optimization of a Microwave Polarimeter for Astronomy with Optical Correlation and Detection
Sensors, 2023 Cosmic Microwave Background (CMB) B-modes detection is the main focus of future CMB experiments because of the valuable information it contains, particularly to probe the physics of the very early universe. For this reason, we have developed an optimized
