Primordial perturbations from inflation
I review the standard analysis of adiabatic scalar and tensor perturbations produced by slow-roll inflation driven by a single scalar field, before going on to discuss recent work on the role of non-adiabatic modes during and after inflation. Isocurvature perturbations correlated with adiabatic modes may be produced during multi-field inflation and would give valuable information about the phys...
متن کاملFormation and Evolution of Primordial Black Holes After Hybrid Inflation
We examine the formation and evolution of primordial black holes (PBH’s) after hybrid inflation. Our goal is to assess the effects of various theoretical uncertainties on the extrapolation from a given inflation model to a spectrum of primordial black hole masses. The context of our work is an examination of the possibility[1, 2] that the dark matter is comprised of Planck-mass black hole remna...
متن کاملThe Primordial Inflation Explorer (PIXIE)
The Primordial Inflation Explorer is an Explorer-class mission to open new windows on the early universe through measurements of the polarization and absolute frequency spectrum of the cosmic microwave background. PIXIE will measure the gravitational-wave signature of primordial inflation through its distinctive imprint in linear polarization, and characterize the thermal history of the univers...
متن کاملPrimordial magnetic fields from inflation?
The hot plasma above the electroweak scale contains (hyper) charged scalar particles which are coupled to Abelian gauge fields. Scalars may interact with gravity in a non-conformally invariant way and thus their fluctuations can be amplified during inflation. These fluctuations lead to creation of electric currents and produce inhomogeneous distribution of charge density, resulting in the gener...
متن کاملMassive Primordial Black Holes in Hybrid Inflation
It is well known that energy density fluctuations at the early Universe give rise primordial black holes (BH) formation [1]. Widespread opinion is that these BHs are small enough with masses somewhere in the range MBH ∼ 10−5 − 10gram depending on specific model. What could be said about BHs with masses in the range 10 − 10gram? There exist a few number of inflationary models that predict BH pro...
