Gravity of gluonic fluctuations and the value of the cosmological constant

Kris Mackewicz, Craig Hogan

We analyze the classical linear gravitational effect of idealized pion-like dynamical systems, consisting of light quarks connected by attractive gluonic material with a stress-ene…

Angular spectrum of quantum fluctuations in causal structure

Craig Hogan, Ohkyung Kwon, Nathaniel Selub

Scaling arguments are used to constrain the angular spectrum of distortions on boundaries of macroscopic causal diamonds, produced by Planck-scale vacuum fluctuations of causally-c…

Angular correlations on causally-coherent inflationary horizons

Craig Hogan, Stephan S. Meyer, Nathaniel Selub +1

We develop a model for correlations of cosmic microwave background anisotropy on the largest angular scales, based on standard causal geometrical relationships in slow-roll inflati…

Symmetries of the Primordial Sky

Craig Hogan

Quantum field theory, which is generally used to describe the origin of large-scale gravitational perturbations during cosmic inflation, has been shown to omit an important physica…

Vacuum Energy Density Measured from Cosmological Data

J. Prat, C. Hogan, C. Chang +1

Within the CDM cosmological model, the absolute value of Einstein's cosmological constant , sometimes expressed as the gravitating mass-energy density of the physical v…

Anomalies of Cosmic Anisotropy from Holographic Universality of Great-Circle Variance

Nathaniel Selub, Frederick Wehlen, Craig Hogan +1

We examine all-sky cosmic microwave background (CMB) temperature maps on large angular scales to compare their consistency with two scenarios: the standard inflationary quantum pic…
