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 educational
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 for being at a seminar
Great tool, I loved it immediately. One important lacking feature is that it doesnt output E(z).
Useful and handy tool
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.
