Chandra deep observation of XDCP J0044.0-2033, a massive galaxy cluster at z>1.5
P. Tozzi, J. S. Santos, M. J. Jee +11
We report the analysis of the Chandra observation of XDCP J0044.0-2033, a massive, distant (z=1.579) galaxy cluster discovered in the XDCP survey. The total exposure time of 380 ks…
SuperModel Analysis of Abell 1246 and J255: on the Evolution of Galaxy Clusters from High to Low Entropy States
R. Fusco-Femiano, A. Lapi
We present an analysis of high-quality X-ray data out to the virial radius for the two galaxy clusters Abell 1246 and GMBCG J255.34805+64.23661 (J255) by means of our entropy-based…
nIFTy Cosmology: Galaxy/halo mock catalogue comparison project on clustering statistics
Chia-Hsun Chuang, Cheng Zhao, Francisco Prada +21
We present a comparison of major methodologies of fast generating mock halo or galaxy catalogues. The comparison is done for two-point and the three-point clustering statistics. Th…
Probing the evolution of galaxy clusters with the SZ Effect
A. Cavaliere, A. Lapi
In galaxy clusters the thermal Sunyaev-Zel'dovich (SZ) effect from the hot intracluster medium (ICM) provides a direct, self-contained measure of the pressure integrated over cross…
Measurements of the Sunyaev-Zel'dovich Effect in MACS J0647.7+7015 and MACS J1206.2-0847 at High Angular Resolution with MUSTANG
Alexander H. Young, Tony Mroczkowski, Charles Romero +18
We present high resolution (9) imaging of the Sunyaev-Zel'dovich Effect (SZE) toward two massive galaxy clusters, MACS J0647.7+7015 () and MACS J1206.2-0…
Hubble Space Telescope Combined Strong and Weak Lensing Analysis of the CLASH Sample: Mass and Magnification Models and Systematic Uncertainties
Adi Zitrin, Agnese Fabris, Julian Merten +23
We present results from a comprehensive lensing analysis in HST data, of the complete CLASH cluster sample. We identify new multiple-images previously undiscovered allowing improve…
