Lagrangian reconstruction of cosmic velocity fields
G. Lavaux
We discuss a Lagrangian reconstruction method of the velocity field from galaxy redshift catalog that takes its root in the Euler equation. This results in a ``functional'' of the…
Using Local Volume data to constrain Dark Matter dynamics
G. Lavaux, R. Mohayaee, S. Colombi +1
The peculiar velocity reconstruction methods allow one to have a deeper insight into the distribution of dark matter: both to measure mean matter density and to obtain the primordi…
Observational biases in Lagrangian reconstructions of cosmic velocity fields
G. Lavaux, R. Mohayaee, S. Colombi +3
Lagrangian reconstruction of large-scale peculiar velocity fields can be strongly affected by observational biases. We develop a thorough analysis of these systematic effects by re…
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…
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…
