The cosmic ionizing background is the diffuse radiation field capable of <photoionization> of intergalactic gas. Its <specific intensity> depends on source <luminosity functions>, <ionizing photon escape fractions>, cosmological redshifting, and <radiative transfer> through absorbers. <Quasars> and <star formation> supply major contributions with different spectral shapes and evolution.
