Description
We present a study of the impact of the environment on the morphokinematics properties of intermediate redshift galaxies (z~0.25-1.5) with the use of HST and MUSE data. We use the latest MUSE-GTO observations of 17 different fields in the COSMOS area from the MAGIC survey to build a sample of ~ 600 resolved galaxies, within target groups and in their foreground and background, allowing to probe a variety of environments,
with virial masses in the range 10^9 - 10^14 M_sol. We perform a multicomponent decomposition from the HST images, and extract the ionised gas kinematics from the MUSE cubes using the [OII] doublet. Taking into account prior information from the morphological decomposition, we perform a mass modelling in order to extract the galaxies main kinematical parameters such as their circular velocity and baryon fraction. After describing our methodology, I will present our results on various scaling relations such as the TFR and show how these scale with structure properties.
