We explore the prospects for using future supernova observations to probe the dark energy. We focus on quintessence, an evolving scalar field that has been suggested as a candidate for the dark energy. After simulating the observations that would be expected from the proposed SuperNova/Acceleration Probe satellite (SNAP), we investigate two methods for extracting information concerning quintessence from such data. First, by expanding the quintessence equation of state as w Q (z) = w Q (0) - a… 

Smoothing supernova data to reconstruct the expansion history of the universe

We propose a non-parametric method of smoothing supernova data over redshift using a Gaussian kernel in order to reconstruct important cosmological quantities including H(z) and w(z) in a

Direct reconstruction of the quintessence potential

We describe an algorithm which directly determines the quintessence potential from observational data, without using an equation of state parametrization. The strategy is to numerically determine

Future supernovae data and quintessence models

The possibility of unambiguously determining the equation of state of the cosmic dark energy with existing and future supernovae data is investigated. We consider four evolution laws for this

Constraints on Extended Quintessence from High-Redshift Supernovae

We obtain constraints on quintessence models from magnitude-redshift measurements of 176 Type Ia supernovae. The considered quintessence models are ordinary quintessence with Ratra-Peebles or

Exploring the expanding Universe and dark energy using the statefinder diagnostic

The coming few years are likely to witness a dramatic increase in high-quality supernova data as current surveys add more high-redshift supernovae to their inventory and as newer and deeper supernova

Probing the expansion history of the universe using upernovae and Baryon Acoustic Oscillations

The standard model of cosmology (the ΛCDM model) has been very successful and is compatible with all observational data up to now. However, it remains an important task to develop and apply null

A new approach to testing dark energy models by observations

We propose a new approach to the consistency test of dark energy models with observations. To test a category of dark energy models, we suggest introducing a characteristic Q(z) that, in general,

Dynamical behavior of generic quintessence potentials: Constraints on key dark energy observables

We perform a comprehensive study of a class of dark energy models--scalar field models where the effective potential can be described by a polynomial series--exploring their dynamical behavior using

A theoretician's analysis of the supernova data and the limitations in determining the nature of dark energy

Current cosmological observations show a strong signature of the existence of a dark energy component with negative pressure. The most obvious candidate for this dark energy is the cosmological

Nonparametric Reconstruction of the Dark Energy Equation of State

A basic aim of ongoing and upcoming cosmological surveys is to unravel the mystery of dark energy. In the absence of a compelling theory to test, a natural approach is to better characterize the



Future supernovae observations as a probe of dark energy

We study the potential impact of improved future supernovae data on our understanding of the dark energy problem. We carefully examine the relative utility of different fitting functions that can be

Current constraints on the dark energy equation of state

We combine complementary datasets from Cosmic Microwave Background (CMB) anisotropy measurements, high redshift supernovae (SN-Ia) observations and data from local cluster abundances and galaxy

Feasibility of reconstructing the quintessential potential using type Ia supernova data

We investigate the feasibility of the method for reconstructing the equation of state and the effective potential of the quintessence field from type Ia supernova (SNIa) data. We introduce a useful

Measuring Time Dependence of Dark Energy Density from Type Ia Supernova Data

Observations of high-redshift supernovae imply an accelerating universe that can only be explained by an unusual energy component such as vacuum energy or quintessence. To assess the ability of

Constraining the quintessence equation of state with SnIa data and CMB peaks

Quintessence has been introduced as an alternative to the cosmological constant scenario to account for the current acceleration of the universe. This new dark energy component allows values of the


The presence of dark energy in the Universe is inferred directly from the accelerated expansion of the Universe, and indirectly, from measurements of cosmic microwave background (CMB) anisotropy.

Supernova data may be unable to distinguish between quintessence and k-essence

Cosmological Parameter Extraction from the First Season of Observations with the Degree Angular Scale Interferometer

The Degree Angular Scale Interferometer (DASI) has measured the power spectrum of the cosmic microwave background anisotropy over the range of spherical harmonic multipoles 100 < l < 900. We compare

Is cosmology consistent

We perform a detailed analysis of the latest CMB measurements (including BOOMERaNG, DASI, Maxima and CBI), both alone and jointly with other cosmological data sets involving, e.g., galaxy clustering

Measurements of Ω and Λ from 42 High-Redshift Supernovae

We report measurements of the mass density, ΩM, and cosmological-constant energy density, ΩΛ, of the universe based on the analysis of 42 type Ia supernovae discovered by the Supernova Cosmology
