CosmoCalc 3.1.1

CosmoCalc serves as a straightforward tool for calculating cosmological distances, providing users with an intuitive interface that facilitates quick selection of reference cosmology and redshift parameters. Upon inputting these variables, CosmoCalc effectively generates a comprehensive range of astronomical distances and scales.

This application proves to be a valuable resource for astronomers, astronomy students, and anyone interested in the quantitative analysis of distances to astronomical entities.

Key functionalities of CosmoCalc include:

• The ability to select cosmological parameters H0, Ωm, and ΩΛ using user-friendly touch-screen controls.
• Access to a variety of standard reference cosmologies, such as Planck 2013, WMAP9, Concordance, and Einstein-deSitter.
• The capability to efficiently calculate luminosity distance, angular diameter distance, lookback time, age of the Universe, comoving volume, and critical density.
• A convenient option to toggle between flat and non-flat cosmologies through a simple click on the interface.
