The Cosmic Neutrino Background [PDF]

open access: yesarXiv
The cosmic neutrino background is like the cosmic microwave background, but less photon-y and more neutrino-ey. The CNB is also less talked about than the CMB, mostly because it's nearly impossible to detect directly. But if it could be detected, it would be interesting in several ways that are discussed.

Standard Clock in primordial density perturbations and cosmic microwave background

open access: yesPhysics Letters B, 2014
Standard Clocks in the primordial epoch leave a special type of features in the primordial perturbations, which can be used to directly measure the scale factor of the primordial universe as a function of time a(t), thus discriminating between inflation ...
