Gravity Waves from Chain Inflation
Amjad Ashoorioon, Katherine Freese
Chain inflation proceeds through a series of first order phase transitions, which can release considerable gravitational waves (GW). We demonstrate that bubble collisions can leave…
Dangerous implications of a minimum length in quantum gravity
Cosimo Bambi, Katherine Freese
The existence of a minimum length and a generalization of the Heisenberg uncertainty principle seem to be two fundamental ingredients required in any consistent theory of quantum g…
The Phantom Bounce: A New Proposal for an Oscillating Cosmology
Katherine Freese, Matthew G. Brown, William H. Kinney
An oscillating universe cycles through a series of expansions and contractions. We propose a model in which ``phantom'' energy with a supernegative pressure () grows rapid…
Natural Inflation: the status after WMAP 3-year data
Katherine Freese, William H. Kinney, Christopher Savage
The model of Natural Inflation is examined in light of recent 3-year data from the Wilkinson Microwave Anisotropy Probe and shown to provide a good fit. The inflaton potential is n…
The Effect of Dark Matter on the First Stars: A New Phase of Stellar Evolution
Katherine Freese, Paolo Gondolo, Douglas Spolyar
Dark matter (DM) in protostellar halos can dramatically alter the current theoretical framework for the formation of the first stars. Heat from supersymmetric DM annihilation can o…
