GUT-Scale Primordial Black Holes: Consequences and Constraints
Richard Anantua, Richard Easther, John T. Giblin
A population of very light primordial black holes which evaporate before nucleosynthesis begins is unconstrained unless the decaying black holes leave stable relics. We show that g…
CMBPol Mission Concept Study: Probing Inflation with CMB Polarization
Daniel Baumann, Mark G. Jackson, Peter Adshead +56
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measu…
Neutrinos and Future Concordance Cosmologies
Peter Adshead, Richard Easther
We review the free parameters in the concordance cosmology, and those which might be added to this set as the quality of astrophysical data improves. Most concordance parameters en…
Fine-tuning criteria for inflation and the search for primordial gravitational waves
Simeon Bird, Hiranya V. Peiris, Richard Easther
We revisit arguments that simple models of inflation with a small red tilt in the scalar power spectrum generically yield an observable tensor spectrum. We show that criteria for f…
Generation and Characterization of Large Non-Gaussianities in Single Field Inflation
Xingang Chen, Richard Easther, Eugene A. Lim
Inflation driven by a single, minimally coupled, slowly rolling field generically yields a negligible primordial non-Gaussianity. We discuss two distinct mechanisms by which a non-…
Constraining Inflation
Peter Adshead, Richard Easther
Slow roll reconstruction is derived from the Hamilton-Jacobi formulation of inflationary dynamics. It automatically includes information from sub-leading terms in slow roll, and fa…
