Methodology of Observational Cosmology

AIP Conference Proceedings, 2003
These lectures focus on the methods of observational cosmology and their physical basis. After a brief reminder of the essential elements of the Big Bang model, we look at some of the basic methods for surveying the homogeneous universe. The second half of the lectures examines the perturbed universe - large-scale structure and the cosmic microwave ...

Ideal observational cosmology

Physics Reports, 1985
Abstract Following Kristian and Sach's direct observational approach to cosmology, this paper analyses in detail the information that can be obtained from idealised astronomical observations, firstly in the cosmographic case when no gravitational field equations are assumed, and secondly in the cosmological case when Einstein's field equations of ...

Observational tests in cosmology

Nature, 1976
IT is often said that the determination of the deceleration term is one of the main aims of observational cosmology. In the following comments this view is questioned, and in a universe of indeterminate density, the third time derivative of the scaling variable is shown to be of greater fundamental importance.

Introduction to Observational Cosmology

2015
An array of recent astrophysical observations show us two unresolved mysteries of cosmology; the accelerating expansion of the universe and the existence of dark matter. In order to realize the cosmic acceleration in General relativity, an exotic form of energy, now called dark energy, should be dominated in the present universe.

‘Observational’ Quantum Cosmology

2010
Following on the appraisal presented in Chap. 2 of Vol. I, the reader may rightfully be asking: Given the framework of quantum cosmology (QC), where are the boundaries of our knowledge, i.e., what exactly constitutes these limits? What are the best directions to move in, and in particular, what predictions or (falsifiable) tests for the universe can be
