Numerical methods comparison for protostellar collapse calculations
B. Commercon, P. Hennebelle, E. Audit +2
The development of parallel supercomputers allows today the detailed study of the collapse and the fragmentation of prestellar cores with increasingly accurate numerical simulation…
AGN self-regulation in cooling flow clusters
A. Cattaneo, R. Teyssier
We use three-dimensional high-resolution adaptive-mesh-refinement simulations to investigate if mechanical feedback from active galactic nucleus jets can halt a massive cooling flo…
The correlation of the Lyman-alpha forest and metals in close pairs of hight-redshift quasars
F. Coppolani, P. Petitjean, F. Stoehr +6
We derive the transverse flux correlation function in the Lyman-alpha forest at z~2.1 from VLT-FORS observations of a total of 32 pairs of quasars. The shape and correlation length…
XMM -Newton observations of merging clusters of galaxies: A3921 and A1750
E. Belsole, J-L. Sauvageot, R. Teyssier
We show the XMM-Newton guaranted time observations of 2 clusters of galaxies in a different stage of merger.
