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…
Singlet Fermionic Dark Matter and the Electroweak Phase Transition
Malcolm Fairbairn, Robert Hogan
We consider a model with a gauge singlet Dirac fermion as a cold dark matter candidate. The dark matter particle communicates with the Standard Model via a gauge singlet scalar med…
