Full-sky maps for gravitational lensing of the CMB
Carmelita Carbone, Volker Springel, Carlo Baccigalupi +2
We use the large cosmological Millennium Simulation (MS) to construct the first all-sky maps of the lensing potential and the deflection angle, aiming at gravitational lensing of t…
The redshift dependence of the structure of massive LCDM halos
Liang Gao, Julio F. Navarro, Shaun Cole +5
(Abridged) We use two very large cosmological simulations to study how the density profiles of relaxed LCDM dark halos depend on redshift and on halo mass. We confirm that these pr…
On the width of cold fronts in clusters of galaxies due to conduction
F. Xiang, E. Churazov, K. Dolag +2
We consider the impact of thermal conduction in clusters of galaxies on the (unmagnetized) interface between a cold gaseous cloud and a hotter gas flowing over the cloud (the so-ca…
The speed of the `bullet' in the merging galaxy cluster 1E0657-56
Volker Springel, Glennys Farrar
Deep Chandra exposures of the hot galaxy cluster 1E0657-56 have revealed that the cluster is observed shortly after the first core-passage of a massive infalling subcluster, which…
Virial Scaling of Massive Dark Matter Halos: Why Clusters Prefer a High Normalization Cosmology
A. E. Evrard, J. Bialek, M. Busha +14
We present a precise estimate of the bulk virial scaling relation of halos formed via hierarchical clustering in an ensemble of simulated cold dark matter cosmologies. The result i…
Simulations of star formation in a gaseous disc around sgr A* - a failed AGN
Sergei Nayakshin, Jorge Cuadra, Volker Springel
We numerically model fragmentation of a gravitationally unstable gaseous disc under conditions that may be appropriate for the formation of the young massive stars observed in the…
