The Early Universe has become the standard reference on forefront topics in cosmology,
particularly to the early history of the Universe. Subjects covered include primordial …

Topological defects are produced during phase transitions in the very early Universe. They
arise in most unified theories of strong, weak and electromagnetic interactions. This article …

Cosmic microwave background and large-scale structure data will shortly improve
dramatically with the Microwave Anisotropy Probe and Planck Surveyor, and the Anglo …

Cosmic strings, if they exist, source nonlinear and non-Gaussian perturbations all the way
back to the time of equal matter and radiation (and earlier). Here, we compute the mass …

After fertilization, the protein products of the Drosophila homeobox gene caudal (cad)
accumulate in a concentration gradient spanning the anteroposterior axis of the develo** …

Daily flux density measurements of 36 extragalactic radio sources over a seven year period
reveal several unusual minima in the light curves that do not follow typical source variations …

The primordial nucleosynthesis and pulsar timing noise constraints on cosmic-string
gravitational radiation are computed. The computation consists of a numerical integration of …

The observed abundance of high-redshift galaxies and clusters contains precious
information about the properties of the initial perturbations. We present a method to compute …

The evolution of density perturbations around cosmic strings in the matter-dominated era is
discussed with attention to the specific nature of string perturbations. The parameter Gμ is …

We study the gravitational back reaction of local cosmic-string loops as they shrink due to
gravitational radiation. We chart the evolution of the shape and radiation rate of the loops …
