Abstract (AI)
A cosmology calculator that computes times and distances as a function of redshift for user‐defined cosmological parameters has been made available online. This paper gives the formulae used by the cosmology calculator and discusses some of its implementation. A version of the calculator that allows one to specify the equation‐of‐state parameter w and w ' , and one for converting the light‐travel times usually given in the popular press into redshifts, is also located at the same site.
Key Findings
1
A companion tool converts commonly reported light-travel times into corresponding cosmological redshifts.
2
An extended calculator allows users to specify the dark-energy equation-of-state parameters w and w′.
3
An online cosmology calculator computes cosmological times and distances as functions of redshift for user-defined parameters.
4
The paper presents the mathematical formulae underlying the calculator and discusses aspects of its implementation.
