Description
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
What’s New
Version 3.1.1
Finally updated for large screen iPhones! Other small bug fixes, Planck 2015 cosmology, and full iOS 10 compatibility, .
Ratings and Reviews
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.
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 doesn't output E(z).
