GAz: A Genetic Algorithm for Photometric Redshift Estimation
Robert Hogan, Malcolm Fairbairn, Navin Seeburn
We present a new approach to the problem of estimating the redshift of galaxies from photometric data. The approach uses a genetic algorithm combined with non-linear regression to…
Unifying inflation and dark matter with the Peccei-Quinn field: observable axions and observable tensors
Malcolm Fairbairn, Robert Hogan, David J. E. Marsh
A model of high scale inflation is presented where the radial part of the Peccei-Quinn (PQ) field with a non-minimal coupling to gravity plays the role of the inflaton, and the QCD…
Electroweak Vacuum Stability in light of BICEP2
Malcolm Fairbairn, Robert Hogan
We consider the effect of a period of inflation with a high energy density upon the stability of the Higgs potential in the early universe. The recent measurement of a large tensor…
The Problem with False Vacuum Higgs Inflation
Malcolm Fairbairn, Philipp Grothaus, Robert Hogan
We investigate the possibility of using the only known fundamental scalar, the Higgs, as an inflaton with minimal coupling to gravity. The peculiar appearance of a plateau or a fal…
