What do we learn by mapping dark energy to a single value of ?
Samuel S. Taylor, Robert J. Scherrer
We examine several dark energy models with a time-varying equation of state parameter, , to determine what information can be derived by fitting the distance modulus in such…
A long freeze is hard to achieve in the presence of matter
Samuel Blitz, Robert J. Scherrer, Oem Trivedi
Certain holographic dark energy (HDE) models allow for the possibility of a ``long freeze,'' in which the scale factor evolves to a constant in the long-time limit. Here we extend…
The long freeze: an asymptotically static universe from holographic dark energy
Samuel Blitz, Robert J. Scherrer, Oem Trivedi
We show that some holographic dark energy models can lead to a future evolution of the universe in which the scale factor is asymptotically constant, while $\dot a \rightarrow…
Gravitational Radiation Power Spectrum of Garfinkle-Vachaspati Cosmic String Loops
S. David Storm, Robert J. Scherrer
We examine the power spectrum of the th harmonic for Garfinkle-Vachaspati cosmic strings, which correspond to planar rectangular loops. While these loop tractories are sel…
New perspectives on future rip scenarios with holographic dark energy
Oem Trivedi, Robert J. Scherrer
We explore the asymptotic future evolution of holographic dark energy (HDE) models, in which the density of the dark energy is a function of a cutoff scale . We develop a genera…
