GUI application for calculating human-visible colors of celestial bodies from their photometric data

A quick guide to intensity and temperature conversion for the black body radiation and in particular the cosmic microwave background (CMB).

A collection of useful programs in astrophysics

Estimate intrinsic properties galaxies

simple script that demonstrates how Planck's law reduces to the Rayleigh-Jeans law at long wavelengths

Sunlight spectra for photoelectrochemistry

This is a version of the boltzmann library that attempts to perform all operations at O(1) It can directly calculate peak energy peek frequency auc and fwhm for any temps at O(1) from that single point. It also caches energy by temp look ups to speed up repeated access of those temps across temps
