The Isotropic Universe

Fields for APM galaxy survey & 2dF redshift survey
The APM survey of 2 million galaxies (mJ < 17)
Small fraction of the 2 million sources in the NVSS (flux > 2.5 mJy) shown on equal area projection. The distribution is remarkably uniform since the radio galaxies are, on average, at z ~ 0.8. (from Jim Condon)


Representation of CMB -- after removal of dipole and MW emission
WMAP image of the CMB, contrast stretched to show the slight anisotropies that become large scale structure.
