Evidence for Non-Hydrostatic Gas from the Cluster X-ray to Lensing Mass Ratio
A. Mahdavi, H. Hoekstra, A. Babul +1
Using a uniform analysis procedure, we measure spatially resolved weak gravitational lensing and hydrostatic X-ray masses for a sample of 18 clusters of galaxies. We find a radial…
A Multiwavelength Analysis of the Strong Lensing Cluster RCS 022434-0002.5 at z=0.778
Amalia K. Hicks, Erica Ellingson, Henk Hoekstra +6
We present the results of two (101 ks total) Chandra observations of the z=0.778 optically selected lensing cluster RCS022434-0002.5, along with weak lensing and dynamical analyses…
The Masses and Shapes of Dark Matter Halos from Galaxy-Galaxy Lensing in the CFHTLS
Laura C. Parker, Henk Hoekstra, Michael J. Hudson +2
We present the first galaxy-galaxy weak lensing results using early data from the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS). These results are based on ~22 sq. deg. of…
A Dark Core in Abell 520
A. Mahdavi, H. Hoekstra, A. Babul +2
The rich cluster Abell 520 (z=0.201) exhibits truly extreme and puzzling multi-wavelength characteristics. It may best be described as a "cosmic train wreck." It is a major merger…
Comparison of weak lensing masses and X-ray properties of galaxy clusters
Henk Hoekstra
We present measurements of the masses of 20 X-ray luminous clusters of galaxies at intermediate redshifts, determined from a weak lensing analysis of deep archival R-band data obta…
