Chandra measurements of non-thermal-like X-ray emission from massive, merging, radio-halo clusters
E. T. Million, S. W. Allen
We report the discovery of spatially-extended, non-thermal-like emission components in Chandra X-ray spectra for five of a sample of seven massive, merging galaxy clusters with pow…
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…
Chandra X-ray observations of the 3C295 cluster core
S. W. Allen, G. B. Taylor, P. E. J. Nulsen +7
We examine the properties of the X-ray gas in the central regions of the distant (z=0.46), X-ray luminous cluster of galaxies surrounding the powerful radio source 3C 295, using ob…
Chandra measurements of the distribution of mass in the luminous lensing cluster Abell 2390
S. W. Allen, S. Ettori, A. C. Fabian
We present spatially-resolved X-ray spectroscopy of the luminous lensing cluster Abell 2390, using observations made with the Chandra observatory. The temperature of the X-ray gas…
Hard X-ray emission from elliptical galaxies
S. W. Allen, T. Di Matteo, A. C. Fabian
We report the detection of hard X-ray emission components in the spectra of six nearby, giant elliptical galaxies observed with the ASCA satellite. The systems studied, which exhib…
