Can WIMP Spin Dependent Couplings explain DAMA data, in light of Null Results from Other Experiments?
Christopher Savage, Paolo Gondolo, Katherine Freese
We examine whether the annual modulation found by the DAMA dark matter experiment can be explained by Weakly Interacting Massive Particles (WIMPs), in light of new null results fro…
The Phantom Bounce: A New Oscillating Cosmology
Matthew G. Brown, Katherine Freese, William H. Kinney
An oscillating universe cycles through a series of expansions and contractions. We propose a model in which ``phantom'' energy with grows rapidly and dominates the late-ti…
Age of the Universe in the Cardassian Model
Christopher Savage, Noriyuki Sugiyama, Katherine Freese
The age of the universe is obtained in a subset of Cardassian models by using WMAP data. Cardassian expansion is a modification to the Friedmann equation that allows the universe t…
Probing Dark Energy Using Its Density Instead of Its Equation of State
Yun Wang, Katherine Freese
The variation of dark energy density with redshift, , provides a critical clue to the nature of dark energy. Since depends on the dark energy equation of state $w_…
Probing the Evolution of the Dark Energy Density with Future Supernova Surveys
Yun Wang, Veselin Kostov, Katherine Freese +2
The time dependence of the dark energy density can be an important clue to the nature of dark energy in the universe. We show that future supernova data from dedicated telescopes (…
