Extrapolation of Hubble Curves
Alexander E. Pavlov
TL;DR
This paper provides exact solutions to the Friedmann equation using elliptic Legendre integrals, accurately modeling the Hubble diagram and extrapolating Hubble curves for high redshift values.
Contribution
It introduces exact solutions in coordinate and conformal time for the Friedmann equation, enhancing the modeling of the Hubble diagram and its extrapolation.
Findings
Exact solutions match observed Hubble data.
Hubble curves can be reliably extrapolated to high redshift.
Both solution methods yield consistent results.
Abstract
We present exact solutions to the Friedmann equation in coordinate time and conformal time in elliptic Legendre integrals. Both approaches describe the modern Hubble diagram with the same accuracy. Hubble curves are extrapolated for large redshift values.
