In the past decade, observational cosmology has had one of the most exciting periods in the past century. The precision with which we have been able to measure cosmological parameters has increased tremendously, while at the same time, we have been surprised beyond our wildest dreams by the results. I review here recent measurements of the expansion rate, geometry, age, matter content, and equation of state of the universe, and discuss the implications for our understanding of cosmology.

On astrophysical bounds of the cosmological constant
Astrophysical bounds on the cosmological constant are examined for spherically symmetric bodies. Similar limits emerge from the hydrostatical and gravitational equilibrium and the validity of theExpand
A Cosmological Model with Static Extra Dimensions and Varying Cosmological Constant
A five dimensional cosmological model with FLRW type Kaluza-Klien metric has been investigated with static extra dimensions and varying cosmological constant. The field equations with static extraExpand
Dark matter and dark energy from quark bag model
We calculate the present expansion of our Universe endowed with relict colored objects - quarks and gluons - that survived hadronization either as isolated islands of quark-gluon "nuggets", or spreadExpand
The Einstein static universe with torsion and the sign problem of the cosmological constant
In the field equations of Einstein?Cartan theory with cosmological constant a static spherically symmetric perfect fluid with spin density satisfying the Weyssenhoff restriction is considered. ThisExpand
Equilibrium of large astrophysical structures in the Newton-Hooke spacetime
Using the scalar and tensor virial equations, the Lane-Emden equation expressing the hydrostatic equilibrium and small oscillations around the equilibrium, we show how the cosmological constant ΛExpand
No quantum gravity signature from the farthest quasars
Context. Strings and other alternative theories describing the quantum properties of space-time suggest that space-time could present a foamy structure and also that, in certain cases, quantumExpand
Observational constraints on holographic tachyonic dark energy in interaction with dark matter
We discuss an interacting tachyonic dark energy model in the context of the holographic principle. The potential of the holographic tachyon field in interaction with dark matter is constructed. TheExpand
Bayesian analysis of the (generalized) Chaplygin gas and cosmological constant models using the 157 gold SNe Ia data
The generalized Chaplygin gas model (GCGM) contains five free parameters that must be constrained using the different observational data. These parameters are: the Hubble constant H0, the parameterExpand
Cluster mass functions in the quintessential universe
We use N-body simulations to measure mass functions in flat cosmological models with quintessence characterized by constant w with w = -1, -2/3 and -1/2. The results are compared with the predictionsExpand
Eleven Spherically Symmetric Constant Density Solutions with Cosmological Constant
Einstein's field equations with cosmological constant are analysed for a static, spherically symmetric perfect fluid having constant density. Five new global solutions are described. One of theseExpand


however (for it was the literal soul of the life of the Redeemer, John xv. io), is the peculiar token of fellowship with the Redeemer. That love to God (what is meant here is not God’s love to men)Expand
