High-Redshift Radio Galaxies as a Cosmological Tool: Exploration of a Key Assumption and Comparison with Supernova Results
Ruth A. Daly, Matthew P. Mory, Erick J. Guerra
There are many different approaches to using observations to constrain or determine the global cosmological parameters that describe our universe. Methods that rely upon a determin…
Cosmological Parameters and Quintessence From Radio Galaxies
Ruth A. Daly, Erick J. Guerra
FRIIb radio galaxies provide a tool to determine the coordinate distance to sources out to redshifts of two. The coordinate distance depends on the present values of global cosmolo…
Determinations of Key Physical Parameters Related to Classical Double Radio Sources
Lin Wan, Ruth A. Daly, E. J. Guerra
Multi-frequency radio observations of the radio bridge of a powerful classical double radio source can be used to determine: the beam power of the jets emanating from the AGN; the…
Global Cosmological Parameters Determined Using Classical Double Radio Galaxies
E. J. Guerra, Ruth A. Daly, Lin Wan
A sample of 20 powerful extended radio galaxies with redshifts between zero and two were used to determine constraints on global cosmological parameters. Data for six radio sources…
Empirical Determinations of Key Physical Parameters Related to Classical Double Radio Sources
Lin Wan, Ruth A. Daly, Erick J. Guerra
Multi-frequency radio observations of the radio bridge of powerful classical double radio sources can be used to determine: the beam power of the jets emanating from the AGN; the t…
Updated Estimates of Global Cosmological Parameters Determined Using Classical Double Radio Galaxies
Erick J. Guerra, Ruth A. Daly, Lin Wan
A sample of 20 powerful extended radio galaxies with redshifts between zero and two were used to determine constraints on global cosmological parameters. Data for six radio sources…
