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 cosmology

2021
Abstract The main strands of observation in cosmology are presented. These are redshift surveys using standard candles; galaxy distributions; age estimates drawing on a number of strands of evidence; and the CMB radiation. The chapter begins with a discussion of systemtic and statistical error in measurements, and explains the ...

Observer dependence in quantum cosmology

Physical Review D, 1993
The main thesis of this paper is that minisuperspace quantum cosmology reproduces the observer dependence of the vacuum found in quantum field theory in curved spacetime. We show that the vacua picked up by the Hartle-Hawking "no boundary" proposal in two different minisuperspaces sharing the same classical limit ($k=0$ and $k=1$ de Sitter ...
