Cosmic microwave background theory. [PDF]
Proc Natl Acad Sci U S A, 1998 A long-standing goal of theorists has been to constrain cosmological parameters that define the structure formation theory from cosmic microwave background (CMB) anisotropy experiments and large-scale structure (LSS) observations. The status and future promise of this enterprise is described. Current band-powers in ℓ-space are

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 ...

Evolution of the cosmic microwave background [PDF]
Physical Review D, 2007 We discuss the time dependence and future of the Cosmic Microwave Background (CMB) in the context of the standard cosmological model, in which we are now entering a state of endless accelerated expansion. The mean temperature will simply decrease until it reaches the effective temperature of the de Sitter vacuum, while the dipole will oscillate as the ...

Anisotropies of the cosmic microwave background [PDF]
La Rivista del Nuovo Cimento, 2002 We review the present status of Cosmic Microwave Background (CMB) anisotropy observations and discuss the main related astrophysical issues, instrumental effects and data analysis techniques. We summarise the balloon-borne and ground-based experiments that, after COBE-DMR, yielded detection or significant upper limits to CMB fluctuations.

Clustering of hotspots in the cosmic microwave background [PDF]
EPJ Web of Conferences, 2019 The physics behind the origin and composition of the Cosmic Microwave Background (CMB) is a well-established topic in the field of Cosmology. Literature on CMB anisotropies reveal consistency with Gaussianity [1], but these were conducted on full multi ...

Running and Running of the Running of the Scalar Spectral Index in Warm Inflation
Universe, 2023 The next generation of cosmological observations are expected to improve the measurements of several quantities connected to the primordial inflation in the early Universe.

Cosmic Microwave Background from Effective Field Theory
Universe, 2019 In this work, we study the key role of generic Effective Field Theory (EFT) framework to quantify the correlation functions in a quasi de Sitter background for an arbitrary initial choice of the quantum vacuum state. We perform the computation in unitary

Computing challenges of the cosmic microwave background [PDF]
Computing in Science & Engineering, 1999 The Cosmic Microwave Background (CMB) encodes information on the origin and evolution of the universe, buried in a fractional anisotropy of one part in 100,000 on angular scales from arcminutes to tens of degrees. We await the coming onslaught of data from experiments measuring the microwave sky from the ground, from balloons and from space.
