A Detailed Study of the Lobes of Eleven Powerful Radio Galaxies

Ruth A. Daly, Preeti Kharb, Christopher P. O'Dea +5

Radio lobes of a sample of eleven very powerful classical double radio galaxies were studied. Each source was rotated so that the symmetry axis of the source was horizontal, and ve…

The Acceleration History of the Universe and the Properties of the Dark Energy

Ruth A. Daly, S. G. Djorgovski

The model-independent method of using type Ia supernovae proposed and developed by Daly and Djorgovski (2003, 2004) has been applied to the Riess et al. (2007) supernovae sample. A…

Improved Constraints on the Acceleration History of the Universe and the Properties of the Dark Energy

Ruth A. Daly, S. G. Djorgovski, Kenneth A. Freeman +4

We extend and apply a model-independent analysis method developed earlier by Daly & Djorgovski to new samples of supernova standard candles, radio galaxy and cluster standard ruler…

Cosmological Studies with Radio Galaxies and Supernovae

Ruth A. Daly, Matthew P. Mory, C. P. O'Dea +4

Physical sizes of extended radio galaxies can be employed as a cosmological "standard ruler", using a previously developed method. Eleven new radio galaxies are added to our previo…

The Properties and Gaseous Environments of Powerful Classical Double Radio Galaxies

Ruth Daly, C. O'Dea, P. Kharb +3

The properties of a sample of 31 very powerful classical double radio galaxies with redshifts between zero and 1.8 are studied. The source velocities, beam powers, ambient gas dens…

A Study of 13 Powerful Classical Double Radio Galaxies

P. Kharb, C. O'Dea, S. Baum +4

We have carried out an extensive study of a sample of 13 large, powerful Fanaroff-Riley type II radio galaxies with the Very Large Array in multiple configurations at 330 MHz, 1.4,…
