Small Field models with ACTPol and BICEP3 data -- Likelihood analysis

Ira Wolfson, Utkarsh Kumar, Ido Ben-Dayan +1

We perform a Bayesian analysis for small field models of inflation, using the most recent datasets produced by Planck`18, ACTPol, and BICEP3. We employ Artificial Neural Networks (…

Analytic Correlation of Inflationary Potential to Power Spectrum Shape: Limits of Validity, and `No-Go' for Small Field Model Analytics

Ira Wolfson

The primordial power spectrum informs the possible inflationary histories of our universe. Given a power spectrum, the ensuing cosmic microwave background is calculated and compare…

Numerical Analysis of the Primordial Power Spectrum for (Small Field) Inflationary Potentials

Ira Wolfson

We study small field models of inflation, which, against previous expectations, yield significant Gravitational Wave (GW) signal while reproducing other measured observable quantit…

Small field models of inflation that predict a tensor-to-scalar ratio

Ira Wolfson, Ram Brustein

Future observations of the cosmic microwave background (CMB) polarization are expected to set an improved upper bound on the tensor-to-scalar ratio of . Recently, w…

Constraints on Scalar and Tensor spectra from

Ido Ben-Dayan, Brian Keating, David Leon +1

At the linear level, the gravitational wave (GW) spectrum predicted by inflation, and many of its alternatives, can have arbitrarily small amplitude and consequently an unconstrain…

Likelihood analysis of small field polynomial models of inflation yielding a high Tensor-to-Scalar ratio

Ira Wolfson, Ram Brustein

Inflationary potentials, with Planckian field excursions, described by a 6th degree polynomial are studied. We solve the Mukhanov-Sasaki equations exactly and employ a probabilisti…

Small field models with gravitational wave signature supported by CMB data

Ira Wolfson, Ram Brustein

We study scale dependence of the cosmic microwave background (CMB) power spectrum in a class of small, single-field models of inflation which lead to a high value of the tensor to…
