Simulating the Universe from the cosmological horizon to halo scales
Thomas Montandon, Oliver Hahn, Clément Stahl
Ultra-large scales close to the cosmological horizon will be probed by the upcoming observational campaigns. They hold the promise to constrain single-field inflation as well as ge…
Hydrodynamical simulations of galaxy formation with non-Gaussian initial conditions
Clément Stahl, Yohan Dubois, Benoit Famaey +4
Collisionless simulations of structure formation with significant local primordial non-Gaussianities at Mpc scales have shown that a non-Gaussian tail favouring underdensities, wit…
Relativistic matter bispectrum of cosmic structures on the light cone
Thomas Montandon, Julian Adamek, Oliver Hahn +4
Upcoming surveys of cosmic structures will probe scales close to the cosmological horizon, which opens up new opportunities for testing the cosmological concordance model to high a…
Dipolar dark matter simulations on galaxy scales with the RAMSES code
Clément Stahl, Benoit Famaey, Guillaume Thomas +2
We numerically explore on galaxy scales the Dipolar dark matter (DM) model based on the concept of gravitational polarization. This DM model has been proposed as a natural way to r…
Exploring the effects of primordial non-Gaussianity at galactic scales
Clément Stahl, Thomas Montandon, Benoit Famaey +2
While large scale primordial non-Gaussianity is strongly constrained by present-day data, there are no such constraints at Mpc scales. Here we investigate the effect of significant…
Relativistic second-order initial conditions for simulations of large-scale structure
J. Adamek, J. Calles, T. Montandon +2
Relativistic corrections to the evolution of structure can be used to test general relativity on cosmological scales. They are also a well-known systematic contamination in the sea…
