I will present the analysis of the stellar population properties in a sample of the so-called jellyfish galaxies observed with MUSE@VLT in the frame of the GASP project. These galaxies take their name from the morphological resemblance to jellyfishes, displaying long tails of gas and newly born stars provoked by the interaction, via ram pressure stripping, between the hot intracluster medium and the gas with the galaxy itself. According to numerical simulations, ram pressure has a double effect: firstly, by compressing the gas within the galaxy, it might provoque an enhancement of the star formation activity, which can lead to an increment in the star formation rate within the galactic disk by up to a factor of 3-5. Later on in the interaction, ram pressure will push the gas that was once inside the galactic disk away, creating long (up to ~80 kpc) tails where star formation can occur. The aim of my work is to study the relation between the “enhanced” star formation activity, and the properties of both the galaxy (stellar mass, morphology, gas content, position within the cluster, velocity) and the cluster it is accreting onto.
