Features & Capabilities

CosmoCalc is a simple cosmological distance calculator. With a simple and intuitive interface you can quickly set a reference cosmology and redshift, and CosmoCalc will calculate a full suite of astronomical distances and scales.

CosmoCalc is a useful and educational reference tool for astronomers, astronomy students, and anybody interested in calculating the distance to astronomical sources.

CosmoCalc allows you to:

Select cosmological parameters H_0, Ω_m, and Ω_Λ with simple touch-screen controls
Easily choose from common reference cosmologies, including Planck 2013, WMAP9, Concordance, and Einstein-deSitter
Quickly determine the luminosity distance, angular diameter distance, lookback time, age of the Universe, comoving volume, and critical density
Easily switch between flat and non-flat cosmologies by clicking on the chain

Never will I need to open a Jupyter notebook everytime I want to calculate some simple cosmology things!

A very handy and useful tool for cosmological calculations. It would be more interesting if we can add nonzero curvature and radiation terms. Also the (as of now) hypothetical term with w=-2/3 should be added for fun.
