The Red Sequence investigated with a novel IFU analysis GUI: metallicity gradients in galaxy cluster

In the recent years, MUSE has been reshaping the way we investigate galaxies in the nearby Universe and at low-intermediate redshift. The collection of a significant amount of datasets and the execution of large programmes and IFU surveys urge us to develop and use fast and reliable programming tools and codes in order to exploit the unique treasure of information we can extract from instruments like MUSE, but also userfriendly analysis tools. I will present a highly customisable and flexible GUI, initially designed for MUSE, for performing (really) fast and reliable full-spectrum template fitting on-the-fly directly on the datacube, without the need of difficult intermediate steps and further coding. As a scientific example, I will present my recent results on the investigation of the metallicity gradient in some galaxy clusters by making use of a synergistic approach involving MUSE and HST data.
