Model independent analysis of dark energy: Supernova fitting result
This paper uses the supernova data to explore the property of dark energy by some model independent methods. We first Taylor expand the scale factor a(t) and the luminosity distance dL to the fifth order to find out that the deceleration parameter q0 < 0. This result just invokes the Robertson-Walker metric. So the conclusion that the universe is expanding with acceleration is more general. The...
متن کاملSupernova constraints on dark energy model
The recent observations support that our universe is flat and expanding with acceleration. A quintessence model with a general relation between the quintessence potential and the quintessence kinetic energy was proposed to explain the phenomenon. The dark energy potential includes both the hyperbolic and the double exponential potentials. We analyze this model in detail by using the recent supe...
متن کاملSupernova Constraints on a holographic dark energy model
In this paper, we use the type Ia supernova data to constrain the model of holographic dark energy. For d = 1, the best fit result is Ω0m = 0.25, the equation of the state of the holographic dark energy w Λ = −0.91 and the transition between the decelerating expansion and the accelerating expansion happened when the cosmological red-shift was zT = 0.72. If we set d as a free parameter, the best...
متن کاملReducing zero-point systematics in dark energy supernova experiments
We study the effect of filter zero-point uncertainties on future supernova dark energy missions. Fitting for calibration parameters using simultaneous analysis of all Type Ia supernova standard candles achieves a significant improvement over more traditional fit methods. This conclusion is robust under diverse experimental configurations (number of observed supernovae, maximum survey redshift, ...
متن کاملSupernova Simulations and Strategies For the Dark Energy Survey
We present an analysis of supernova light curves simulated for the upcoming Dark Energy Survey (DES) supernova search. The simulations employ a code suite that generates and fits realistic light curves in order to obtain distance modulus/redshift pairs that are passed to a cosmology fitter. We investigated several different survey strategies including field selection, supernova selection biases...
