The formula for the Doppler shift, which astronomers denote by the letter z z, is. However, in a Universe with matter, at least some of any observed redshift should be attributed to gravitational effects, and in any case the precise recessional velocity of a galaxy several billion years ago is of little real interest. Redshift is the world’s first fully GPU-accelerated, biased renderer. To quantitatively examine this hypothesis, we calculate quasar luminosity functions (LFs) by manipulating the observed galaxy LFs ( z ≲ 2) and theoretical merger . e.
