Radio Galaxy Redshift-Angular Size Data Constraints on Dark Energy

Silviu Podariu, Ruth A. Daly, Matthew P. Mory +1

We use FRIIb radio galaxy redshift-angular size data to constrain cosmological parameters in a dark energy scalar field model. The derived constraints are consistent with but weake…

Cosmological Parameter Determination from Counts of Galaxies

Silviu Podariu, Bharat Ratra

We study constraints that anticipated DEEP survey galaxy counts versus redshift data will place on cosmological model parameters in models with and without a constant or time-varia…

Binned Cosmic Microwave Background Anisotropy Power Spectra: Peak Location

Silviu Podariu, Tarun Souradeep, J. Richard Gott +2

We use weighted mean and median statistics techniques to combine individual cosmic microwave background (CMB) anisotropy detections and determine binned, multipole-space, CMB aniso…

Cosmological-Model-Parameter Determination from Satellite-Acquired Type Ia and IIP Supernova Data

Silviu Podariu, Peter Nugent, Bharat Ratra

We examine the constraints that satellite-acquired Type Ia and IIP supernova apparent magnitude versus redshift data will place on cosmological model parameters in models with and…

Median Statistics, H_0, and the Accelerating Universe

J. Richard Gott, Michael S. Vogeley, Silviu Podariu +1

(Abridged) We develop median statistics that provide powerful alternatives to chi-squared likelihood methods and require fewer assumptions about the data. Applying median statistic…

Supernovae Ia Constraints on a Time-Variable Cosmological "Constant"

Silviu Podariu, Bharat Ratra

The energy density of a scalar field with potential , , behaves like a time-variable cosmological constant that could contribute significantly to the…
