Team: Clusters of galaxies. Ionized gas around active galactic nuclei. .
In X-rays, search for substructures using the wavelet analysis, modelling of the X-ray gas, deriving the dark matter distribution.
At optical wavelengths (imaging and spectroscopy): substructures, luminosity function and dynamical properties.
Smoothed image of Abell 85 observed with the ROSAT PSPC, showing excess emission to the south east. This excess appears to be due to groups falling on to the main cluster.
Wavelet reconstuction of the image of Abell 85 observed with the ROSAT PSPC, confirming the presence of an X-ray filament at least 4 Mpc in length (see Durret F., Forman W., Gerbal D., Jones C., Vikhlinin A. 1998, A&A 335, 41).
