Ultracompact minihalos as probes of inflationary cosmology
Grigor Aslanyan, Layne C. Price, Jenni Adams +5
Cosmological inflation generates primordial density perturbations on all scales, including those far too small to contribute to the cosmic microwave background. At these scales, is…
Designing and testing inflationary models with Bayesian networks
Layne C. Price, Hiranya V. Peiris, Jonathan Frazer +1
Even simple inflationary scenarios have many free parameters. Beyond the variables appearing in the inflationary action, these include dynamical initial conditions, the number of f…
Learn-As-You-Go Acceleration of Cosmological Parameter Estimates
Grigor Aslanyan, Richard Easther, Layne C. Price
Cosmological analyses can be accelerated by approximating slow calculations using a training set, which is either precomputed or generated dynamically. However, this approach is on…
Signatures of the Very Early Universe: Inflation, Spatial Curvature and Large Scale Anomalies
Grigor Aslanyan, Richard Easther
A short inflationary phase may not erase all traces of the primordial universe. Associated observables include both spatial curvature and "anomalies" in the microwave background or…
