The prospects for constraining dark energy with future X-ray cluster gas mass fraction measurements
David Rapetti, Steven W. Allen, Adam Mantz
We examine the ability of a future X-ray observatory to constrain dark energy via measurements of the cluster X-ray gas mass fraction, fgas. We find that fgas measurements for a sa…
Probing Dark Energy with Constellation-X
David Rapetti, Steven W. Allen, Con-X Facility Science Team
Constellation-X (Con-X) will carry out two powerful and independent sets of tests of dark energy based on X-ray observations of galaxy clusters, providing comparable accuracy to ot…
A kinematical approach to dark energy studies
David Rapetti, Steven W. Allen, Mustafa A. Amin +1
We present and employ a new kinematical approach to cosmological `dark energy' studies. We construct models in terms of the dimensionless second and third derivatives of the scale…
Constraining Dark Energy with X-ray Galaxy Clusters, Supernovae and the Cosmic Microwave Background
David Rapetti, Steven W. Allen, Jochen Weller
We present new constraints on the evolution of dark energy from an analysis of Cosmic Microwave Background, supernova and X-ray galaxy cluster data. Our analysis employs a minimum…
