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…
