Galaxies are constantly fed by the diffuse material from the intergalactic medium through the Circum-Galactic Medium (CGM). Strong outflows form SN or AGN feedback expel the enriched material back to the CGM. We can probe these vast gaseous haloes around galaxies by studying absorbers detected in the spectra of bright background quasars. To understand the dynamics of the system we combine the physical properties from the absorption features with the broader view of the absorber's host and its environment by emission diagnostics, using the IFU spectroscopy. In this talk, I will present the preliminary results of the study of quasar fields with 12 large N(HI) absorbers and 38 z < 1 galaxies associated with these systems, found within an impact parameter of 200 kpc from the quasar sightline. We find that each absorption systems is not clearly linked to a single galaxy, but instead can be associated to pairs or groups of galaxies. Using a multi-wavelength datasets (UVES, HST, MUSE, ALMA) we are further able to study in detail the properties of the absorbing gas as well as the galaxies associated with the quasar absorbers. Such studies of the gas kinematics and metallicity and the general CGM properties of the absorber host galaxies help to better constrain galaxy evolution models.
