Joint Analysis of Cluster Observations: II. Chandra/XMM-Newton X-ray and Weak Lensing Scaling Relations for a Sample of 50 Rich Clusters of Galaxies
A. Mahdavi, H. Hoekstra, A. Babul +3
We present a study of multiwavelength X-ray and weak lensing scaling relations for a sample of 50 clusters of galaxies. Our analysis combines Chandra and XMM-Newton data using an e…
The Canadian Cluster Comparison Project: weak lensing masses and SZ scaling relations
Henk Hoekstra, Andisheh Mahdavi, Arif Babul +1
The Canadian Cluster Comparison Project is a comprehensive multi-wavelength survey targeting 50 massive X-ray selected clusters of galaxies to examine baryonic tracers of cluster m…
A Giant Metrewave Radio Telescope/Chandra view of IRAS 09104+4109: A type 2 QSO in a cooling flow
Ewan O'Sullivan, Simona Giacintucci, Arif Babul +8
IRAS 09104+4109 is a rare example of a dust enshrouded type 2 QSO in the centre of a cool-core galaxy cluster. Previous observations of this z=0.44 system showed that as well as po…
CLASH: Mass Distribution in and around MACS J1206.2-0847 from a Full Cluster Lensing Analysis
Keiichi Umetsu, Elinor Medezinski, Mario Nonino +45
We derive an accurate mass distribution of the galaxy cluster MACS J1206.2-0847 (z=0.439) from a combined weak-lensing distortion, magnification, and strong-lensing analysis of wid…
A Study of the Dark Core in A520 with Hubble Space Telescope: The Mystery Deepens
M. J. Jee, A. Mahdavi, H. Hoekstra +4
We present a Hubble Space Telescope/Wide Field Planetary Camera 2 weak-lensing study of A520, where a previous analysis of ground-based data suggested the presence of a dark mass c…
Evolution of the Red Sequence Giant to Dwarf Ratio in Galaxy Clusters out to z ~ 0.5
C. Bildfell, H. Hoekstra, A. Babul +9
We analyze deep g' and r' band data of 97 galaxy clusters imaged with MegaCam on the Canada-France-Hawaii telescope. We compute the number of luminous (giant) and faint (dwarf) gal…
CLASH: Precise New Constraints on the Mass Profile of Abell 2261
Dan Coe, Keiichi Umetsu, Adi Zitrin +43
We precisely constrain the inner mass profile of Abell 2261 (z=0.225) for the first time and determine this cluster is not "over-concentrated" as found previously, implying a forma…
