Hagedorn Inflation: Open Strings on Branes Can Drive Inflation
Steven Abel, Katherine Freese, Ian Kogan
We demonstrate an inflationary solution to the cosmological horizon problem during the Hagedorn regime in the early universe. Here the observable universe is confined to three spat…
An Accelerating Universe from Dark Matter Interactions with Negative Pressure
Paolo Gondolo, Katherine Freese
As an explanation for the acceleration of the universe, we propose dark matter with self-interactions characterized by a negative pressure; there is no vacuum energy whatsoever in…
A Wavelet Analysis of Solar Climate Forcing: I) Solar Cycle Timescales
Matthew J. Lewis, Katherine Freese
We use the technique of wavelet analysis to quantitatively investigate the role of solar variability in forcing terrestrial climate change on solar cycle timescales (roughly 11 yea…
Death of Stellar Baryonic Dark Matter Candidates
Katherine Freese, Brian Fields, David Graff
The nature of the dark matter in the Universe is one of the outstanding questions in astrophysics. In this talk, I address possible stellar baryonic contributions to the 50-90% of…
Limits on Stellar Objects as the Dark Matter of Our Halo: Nonbaryonic Dark Matter Seems to be Required
Katherine Freese, Brian Fields, David Graff
The nature of the dark matter in the Halo of our Galaxy remains a mystery. Arguments are presented that the dark matter does not consist of ordinary stellar or substellar objects,…
Natural Inflation
Katherine Freese
A pseudo-Nambu-Goldstone boson, with a potential of the form , can naturally give rise to an epoch of inflation in the early universe (Freese, Frieman,…
