Probing dark energy beyond $z=2$ with CODEX
Probing dark energy CODEX cosmological redshift
2012/2/21
Precision measurements of nature's fundamental couplings and a first measurement of the cosmological redshift drift are two of the key targets for future high-resolution ultra-stable spectrographs suc...
Dark Energy as Double N-Flation--Observational Predictions
Dark Energy as Double N-Flation--Observational Predictions
2010/11/15
We propose a simple model for dark energy useful for comparison with observations. This is based on the idea that dark energy and inflation should be caused by exactly the same physical process.
Dark energy constraints from a space-based supernova survey
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/23
We present a forecast of dark energy constraints that could be obtained from a large sample of distances to Type Ia supernovae detected and measured from space. We simulate the supernova events as the...
Variable G correction to statefinder parameters of dark energy
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/23
Motivated by several observational and theoretical developments concerning the variability of Newton's gravitational constant with time $G(t)$, we calculate the varying $G$ correction to the statefind...
