SZ polarisation as a probe of the intracluster medium
G. Lavaux, J. M. Diego, H. Mathis +1
We present high-resolution hydrodynamical simulations of the degree and direction of polarisation imprinted on the CMB by the Sunyaev-Zel'dovich effect in the the line of sight to…
On the formation of cold fronts in massive mergers
H. Mathis, G. Lavaux, J. M. Diego +1
Using adiabatic hydrodynamical simulations, we follow the evolution of two symmetric cold fronts developing in the remnant of a violent z=0.3 massive cluster merger. The structure…
WIMP matter power spectra and small scale power generation
C. Boehm, H. Mathis, J. Devriendt +1
Dark Matter (DM) is generally assumed to be massive, cold and collisionless from the structure formation point of view. A more correct statement however is that DM indeed experienc…
Simulating the Formation of the Local Galaxy Population
H. Mathis, G. Lemson, V. Springel +4
We simulate the formation and evolution of the local galaxy population starting from initial conditions with a smoothed linear density field which matches that derived from the IRA…
The case for non-gaussianity on cluster scales
H. Mathis, J. M. Diego, Joseph Silk
We address whether possible scale-dependent deviations from gaussianity in the primordial density field that are consistent with the cosmic microwave background observations could…
Probing the origins of voids with the CMB
L. M. Ord, M. Kunz, H. Mathis +1
In this talk presented at the 5th Rencontres du Vietnam 2004, we discuss our preliminary investigations into voids of primordial origin. We show that if voids in the cold dark matt…
Voids in the Simulated Local Universe
H. Mathis, S. D. M. White
We use simulations of the formation and evolution of the galaxy population in the Local Universe to address the issue of whether the standard theoretical model succeeds in producin…
Constraining CMB-consistent primordial voids with cluster evolution
H. Mathis, J. Silk, L. M. Griffiths +1
Using cosmological simulations, we make predictions for the distribution of clusters in a plausible non-gaussian model where primordial voids nucleated during inflation act togethe…
