Cosmological observatories [PDF]

Classical and Quantum Gravity
Abstract We study the static patch of de Sitter space in the presence of a timelike boundary. We impose that the conformal class of the induced metric and the trace of the extrinsic curvature, K, are fixed at the boundary. We present the thermodynamic structure of de Sitter space subject to these boundary conditions, for static and ...

Axion Cosmology [PDF]

, 2015
Axions comprise a broad class of particles that can play a major role in explaining the unknown aspects of cosmology. They are also well-motivated within high energy physics, appearing in theories related to CP -violation in the standard model ...

Quantum Mechanics in the Light of Quantum Cosmology [PDF]

, 2018
We sketch a quantum mechanical framework for the universe as a whole. Within that framework we propose a program for describing the ultimate origin in quantum cosmology of the quasiclassical domain of familiar experience and for characterizing the ...

Chaos and Order: Contemporary Cosmology and Myth

Etnoantropološki Problemi, 2020
The paper offers a definition of cosmology and its connections with mythology, and presents contemporary theories as a secular mythical narrative suitable for anthropological analysis. The paper is dedicated to emphasizing the folklore characteristics of

Parity-violation in bouncing cosmology

Journal of High Energy Physics, 2023
We investigate the possibility of the enhancement of parity-violation signal in bouncing cosmology. Specifically, we are interested in deciding which phase should generate the most significant parity-violation signals.

Cosmology with the Square Kilometre Array by SKA-Japan

, 2016
In the past several decades, the standard cosmological model has been established and its parameters have been measured to a high precision, while there are still many of the fundamental questions in cosmology; such as the physics in the very early ...

Infinity in string cosmology: A review through open problems [PDF]

, 2016
We review recent developments in the field of string cosmology with particular emphasis on open problems having to do mainly with geometric asymptotics and singularities.

Bouncing cosmology in f(Q) symmetric teleparallel gravity [PDF]

The European Physical Journal Plus, 2020
We consider f(Q) extended symmetric teleparallel cosmologies, where Q is the non-metricity scalar, and constrain its functional form through the order reduction method.
