Clusters of Galaxies: New Results from the CLEF Hydrodynamics Simulation
S. T. Kay, A. C. da Silva, N. Aghanim +5
Preliminary results are presented from the CLEF hydrodynamics simulation, a large (N=2(428)^3 particles within a 200 Mpc/h comoving box) simulation of the LCDM cosmology that inclu…
The CLEF-SSH simulation project
A. C. da Silva, S. T. Kay, N. Aghanim +5
The CLEF-SSH simulation project is an international collaboration, involving the IAS, LATT and the University of Sussex, to produce large hydrodynamic simulations of large-scale st…
CMB Quadrupole induced polarisation from clusters and filaments
Guo-Chin Liu, Antonio da Silva, Nabila Aghanim
We present the estimates of the Cosmic Microwave Background (CMB) polarisation power spectrum from galaxy clusters and filaments using hydrodynamical simulations of large scale str…
Primordial quadrupole-induced polarisation from filamentary structures and galaxy clusters
Guo Chin Liu, Antonio da Silva, Nabila Aghanim
We present the first computation of the Cosmic Microwave Background (CMB) polarisation power spectrum from galaxy clusters and filaments using hydrodynamical simulations of large s…
The distance duality relation from X-ray and SZ observations of clusters
Jean-Philippe Uzan, Nabila Aghanim, Yannick Mellier
X-ray and Sunyaev-Zel'dovich data of clusters of galaxies enable to construct a test of the distance duality relation between the angular and luminosity distances. We argue that su…
Separating the kinetic SZ effect from primary CMB fluctuations
O. Forni, N. Aghanim
In the present work, we propose a new method aiming at extracting the kinetic Sunyaev-Zel'dovich (KSZ) temperature fluctuations embedded in the primary anisotropies of the cosmic m…
