Constraints on modified gravity from the observed X-ray luminosity function of galaxy clusters
David Rapetti, Steven W. Allen, Adam Mantz +1
We use measurements of the growth of cosmic structure, as inferred from the observed evolution of the X-ray luminosity function (XLF) of galaxy clusters, to constrain departures fr…
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…
New constraints on dark energy from the observed growth of the most X-ray luminous galaxy clusters
A. Mantz, S. W. Allen, H. Ebeling +1
We present constraints on the mean matter density, Omega_m, the normalization of the density fluctuation power spectrum, sigma_8, and the dark-energy equation-of-state parameter, w…
Improved constraints on dark energy from Chandra X-ray observations of the largest relaxed galaxy clusters
S. W. Allen, D. A. Rapetti, R. W. Schmidt +3
We present constraints on the mean matter density, Omega_m, dark energy density, Omega_de, and the dark energy equation of state parameter, w, using Chandra measurements of the X-r…
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…
