Non–Gaussian Primordial Fluctuations in Inflationary Cosmology
We analyze the non–Gaussian primordial fluctuations which are inescapably contributed by scalar fields Φ with vanishing expectation values, 〈Φ〉 = 0, present during inflation in addition to the inflaton field. For simplicity we take Φ to be non–interacting and minimally coupled to gravity. Φ is a Gaussian variable, but the energy density fluctuations contributed by such a field are χ–distributed...
متن کاملExtracting primordial density fluctuations
The combination of detections of anisotropy in cosmic microwave background radiation and observations of the large-scale distribution of galaxies probes the primordial density fluctuations of the universe on spatial scales varying by three orders of magnitude. These data are found to be inconsistent with the predictions of several popular cosmological models. Agreement between the data and the ...
متن کاملPrimordial Non-Gaussianity in Models with Dark Matter Isocurvature Fluctuations
We investigate primordial non-Gaussianity and dark matter isocurvature fluctuations in the modulated reheating and the curvaton scenarios. In these scenarios, large non-Gaussianity can be generated, on the other hand, depending on how dark matter is produced, too large isocurvature fluctuations can also arise, which is inconsistent with current observations. In this paper, we study this issue i...
متن کاملPrimordial Fluctuations from Gaugino Condensation
I present a model for inflation based on the gaugino-dilaton dynamics of supersymmetry breaking. The inflaton is the dimension–1 scalar field φ related to the gaugino condensate via λTλ = φ. Recent work in this area is used to obtain two significant results: (1) Scalar density fluctuations at second horizon crossing are generated on scale λ with amplitude
متن کاملGalaxy Evolution from Primordial Fluctuations
The forwards approach to galaxy formation and evolution is extremely powerful but leaves several questions unanswered. Foremost among these is the origin of disks. A backwards approach is able to provide a more realistic treatment of star formation and feedback and provides a practical guide to eventually complement galaxy formation ab initio.
