Analysis of the Omega Diagram for Cosmic Microwave Background Anisotropy and Type Ia Supernovae
نویسنده
چکیده
The fate of the universe depends largely on its energy density relative to the critical energy density. This energy density consists of both matter energy and vacuum energy (also known as dark energy). Experimental data from Type Ia supernovae and from cosmic microwave background anisotropy measurements, when plotted on the Omega diagram as a graph of ΩΛ versus Ωm, conveniently constrains the values of the two Ω parameters to ΩΛ ≈ 2Ωm ≈ 2/3. This paper presents a physical explanation to elucidate the relative positions of these constraints and their uncertainties.

Probing dark energy: Methods and strategies
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. Dark energy contributes about two-thirds of the critical density, is smoothly distributed, has large negative pressure, and is very mysterious. For now, all of its discernible cosmological consequence...
متن کاملConstraints on Cardassian Expansion from Distant type Ia Supernovae
The distant type Ia supernovae data compiled by Perlmutter et al. (1999) are used to analyze the Cardassian expansion scenario, which was recently proposed by Freese and Lewis (2002) as an alternative to a cosmological constant (or more generally a dark energy component) in explaining the currently accelerating universe. We show that the allowed intervals for n and zeq, the two parameters of th...

We have succeeded in establishing a cosmological model with a non-minimally coupled scalar field φ that can account not only for the spatial periodicity or the picket-fence structure exhibited by the galaxy N -z relation of the 2dF survey but also for the spatial power spectrum of the cosmic microwave background radiation (CMB) temperature anisotropy observed by the WMAP satellite. The Hubble d...

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. Dark energy contributes about 2/3 of the critical density, is very smoothly distributed, and has large negative pressure. Its nature is very much unknown. Most of its discernible consequences follow fr...
متن کاملOptions for cosmology at redshifts above one
We show that detailed exploration of the 1 < z < 2 redshift region can provide for definitive testing not only of the standard inflationary cosmological paradigm with its fine-tuned cosmological constant and its mysteriously late (z < 1) onset of cosmic acceleration, but also for the non finetuned, alternate conformal cosmological model, a cosmology which accelerates both above and below z = 1....
