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
Latest reviews of CosmoCalc app for iPhone and iPad
Very esoteric for most, but for the educated layman interested in cosmology, this a a really cool tool. V2.2 seems to have lost the ability to unchain the total mass/energy sum. Do we have to take as fact that Omega is equal 1?
Great tool, I loved it immediately. One important lacking feature is that it doesnt output E(z).
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.
