Forecast Constraints on Inflation from Combined CMB and Gravitational Wave Direct Detection Experiments
Sachiko Kuroyanagi, Christopher Gordon, Joseph Silk +1
We study how direct detection of the inflationary gravitational wave background constrains inflationary parameters and complements CMB polarization measurements. The error ellipsoi…
Artificial Neural Network Modeling of Forest Tree Growth
Christopher Gordon
The problem of modeling forest tree growth curves with an artificial neural network (NN) is examined. The NN parametric form is shown to be a suitable model if each forest tree plo…
Density perturbations in the brane-world
Christopher Gordon, Roy Maartens
In Randall-Sundrum-type brane-world cosmologies, density perturbations generate Weyl curvature in the bulk, which in turn backreacts on the brane via stress-energy perturbations. O…
Adiabatic and entropy perturbations from inflation
Christopher Gordon, David Wands, Bruce A. Bassett +1
We study adiabatic (curvature) and entropy (isocurvature) perturbations produced during a period of cosmological inflation that is driven by multiple scalar fields with an arbitrar…
Large Scale Structure Forecast Constraints on Particle Production During Inflation
Teeraparb Chantavat, Christopher Gordon, Joseph Silk
Bursts of particle production during inflation provide a well-motivated mechanism for creating bump like features in the primordial power spectrum. Current data constrains these fe…
The Amplitude of Dark Energy Perturbations
Christopher Gordon, David Wands
We propose a model which produces dark energy perturbations large enough to explain the lack of power seen at the quadrupole scale in the cosmic microwave background. If the dark e…
