The recent announcement from the Wilkinson Microwave Anisotropy Probe (WMAP) satellite experiment combined with other recent advances in observational cosmology verifies key components of the standard cosmological model. However, [ Bridle et al .][1] argue in their Perspective that there remain some significant open issues regarding the basic history and composition of the Universe and uncertainties in some of the most important parameters.

The state of the Universe
TLDR
The past 20 years have seen dramatic advances in cosmology, mostly driven by observations from new telescopes and detectors, but the emerging ‘standard’ model leaves many details of galaxy formation still to be worked out. Expand
Cosmographic analysis of dark energy
The Hubble relation between distance and redshift is a purely cosmographic relation that depends only on the symmetries of a FLRW spacetime, but does not intrinsically make any dynamical assumptions.Expand
A Toy Model of Complete Cosmic History
In the present paper, we study a toy cosmological model derived from the specific behavior of the Hubble parameter and the scale factor in a spatially-flat Friedmann-Robertson-Walker (FRW)Expand
Prospects for dark energy evolution: a frequentist multi-probe approach
A major quest in cosmology is to understand the nature of dark energy. It is now well known that the use of several cosmological probes is required to break the underlying degeneracies onExpand
Dark Energy Constraints from the CTIO Lensing Survey
We perform a cosmological parameter analysis of the 75 deg2 CTIO lensing survey in conjunction with cosmic microwave background (CMB) and Type Ia supernovae data. For ΛCDM cosmologies, we find thatExpand
Confidence Level Estimator of Cosmological Parameters
Cosmological Models frequently suggest the existence of physical, quantities, e.g. dark energy, we cannot yet observe and measure directly. Their values are obtained indirectly setting them equal toExpand
Development of the Universe and New Cosmology
Cosmology is undergoing an explosive period of activity, fueled both by new, accurate astrophysical data and by innovative theoretical developments. Cosmological parameters such as the total densityExpand
Cosmology With Axionic-quintessence Coupled with Dark Matter
We study the possibility of explaining the late time acceleration with an axion field which is coupled with the dark matter sector of the energy budget of the Universe. The axion field arises fromExpand
Cosmological parameter estimation with large scale structure and supernovae data
Most cosmological parameter estimations are based on the same set of observations and are therefore not independent. Here, we test the consistency of parameter estimations using a combination ofExpand
Observing Baryon Oscillations with Cosmic Shear
A cosmic shear survey, spanning a significant proportion of the sky, should greatly improve constraints on a number of cosmological parameters. It also provides a unique opportunity to examine theExpand

Observational Evidence from Supernovae for an Accelerating Universe and a Cosmological Constant
We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the redshift range 0.16 " z " 0.62. The luminosity distances of these objects are determined by methods thatExpand
Constraints on Ωm and σ8 from Weak Lensing in Red-Sequence Cluster Survey Fields
We have analyzed 53 deg2 of RC-band imaging data from the Red-Sequence Cluster Survey (RCS) and measured the excess correlations in the shapes of galaxies on scales out to ~15. We separate the signalExpand
Constraints on Omega_m and sigma_8 from weak lensing in RCS fields
We have analysed 53 square degrees of imaging data from the Red-Sequence Cluster Survey (RCS), and measured the excess correlations in the shapes of galaxies on scales out to ~1.5 degrees. WeExpand
A Cyclic Model of the Universe
TLDR
A cosmological model in which the universe undergoes an endless sequence of cosmic epochs that begin with a "bang" and end in a “crunch" is proposed, which produces the homogeneity, flatness, and energy needed to begin the next cycle. Expand
Measurements of $\Omega$ and $\Lambda$ from 42 high redshift supernovae
We report measurements of the mass density, Omega_M, and cosmological-constant energy density, Omega_Lambda, of the universe based on the analysis of 42 Type Ia supernovae discovered by the SupernovaExpand
Molecular mechanisms of photosynthesis
TLDR
This chapter discusses the organization and structure of Photosynthetic Systems, as well as the history and development of Photosynthesis, and the origins and evolution of photosynthesis. Expand
