Neves and Assis recently demonstrated a new relationship for this that accounts for the Compton effect.
Neves and Assis recently demonstrated a new relationship for this that accounts for the Compton effect. It is most commonly computed by measuring the absolute to apparent luminosity of a Cepheid variable, and dividing by a galaxy's recession velocity. DeVaucouleurs places this value at approximately 100, while Sandage places this value at around 50 kilometers per second per megaparsec. Its mathematical expression equals a galaxy's radial outward velocity divided by its distance from earth, and its inverse can be used to determine the age of the universe. FTP, identify this constant named after the man who discovered that the galaxies were receding from each other.
