CMB as Bias
CMB as bias refers to the effect of the cosmic microwave background (CMB) on the observed distribution of galaxies. The CMB is the faint radiation left over from the Big Bang, and it has a very specific temperature and polarization pattern. The presence of galaxies can distort this pattern, causing a bias in the observed CMB. This bias can be used to study the properties of galaxies and the large-scale structure of the universe.
