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…
The XMM-Newton Project
J. G. Bartlett, N. Aghanim, M. Arnaud +16
The abundance of high-redshift galaxy clusters depends sensitively on the matter density $\OmM$ and, to a lesser extent, on the cosmological constant . Measurements of this abun…
Sunyaev-Zel'dovich constraints from black hole-seeded proto-galaxies
N. Aghanim, C. Balland, J. Silk
Recent studies of galactic nuclei suggest that most galaxies are seeded by super-massive black holes which power the central nucleus. In this picture, the proto-galactic object is…
A Sunyaev-Zel'dovich map of the massive core in the luminous X-ray cluster RXJ1347-1145
E. Pointecouteau, M. Giard, A. Benoit +5
We have mapped the Sunyaev-Zel'dovich decrement (hereafter SZ) in the direction of the most luminous X-ray cluster known to date, RXJ1347-1145, at z=0.451. This has been achieved w…
Moving Gravitational Lenses: imprints on the CMB
N. Aghanim, S. Prunet, 0. Forni +1
With the new generation of instruments for Cosmic Microwave Background (CMB) observations aiming at an accuracy level of a few percent in the measurement of the angular power spect…
