Generation of primordial cosmological density inhomogeneities with scale invariant power spectrum during the standard radiation dominated expansion of the universe
David H. Oaknin
The most distinctive feature of the primordial density inhomogeneities that existed in the cosmic plasma at the instant of decoupling is their scale invariant power spectrum ${\cal…

Acoustic peaks in the CMB: a matter of standard causal boundary conditions on primordial density anisotropies
David H. Oaknin
The pattern of acoustic peaks in the sub-horizon power spectrum of primordial density anisotropies at recombination can be naturally understood in the framework of standard Friedma…

Spatial correlations of primordial density fluctuations in the standard cosmological model
David H. Oaknin
We revisit the {\it origin of structures problem} of standard Friedmann-Robertson-Walker cosmology to point out an unjustified approximation in the prevalent analysis. We follow co…
