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 ...

The SPIDER CMB Polarimeter [PDF]
, 2012 SPIDER is a balloon-borne millimeter-wave telescope designed to study the polarization of the Cosmic Microwave Background (CMB). SPIDER will map 10% of the full sky with degree-scale beams to search for the distinctive inflationary gravitational wave ...

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.

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.

CMB as a Probe of New Physics and Old Times [PDF]
, 2013 Cosmic birefringence (CB)---a rotation of photon-polarization plane in vacuum---is a generic signature of new scalar fields that could provide dark energy. Previously, WMAP observations excluded a uniform CB-rotation angle larger than a degree.

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

Self-Similar Symmetry Model and Cosmic Microwave Background
Frontiers in Applied Mathematics and Statistics, 2016 In this paper, we present the self-similar symmetry (SSS) model that describes the hierarchical structure of the universe. The model is based on the concept of self-similarity, which explains the symmetry of the cosmic microwave background (CMB).

Primordial Non-Gaussianity in the Cosmic Microwave Background
Advances in Astronomy, 2010 In the last few decades, advances in observational cosmology have given us a standard model of cosmology. We know the content of the universe to within a few percent.
