The impact of orbital history on star formation
It has been observed that internal and external factors significantly influence the star formation of galaxies, depending on both their stellar mass and the environment in which they have evolved. In this work, we present a preliminary analysis of the conditions that lead to the quenching of star formation in groups of galaxies using the hydrodynamical cosmological simulations IllustrisTNG 300-1. Our focus is on the population of galaxies in transition, known as the Green Valley, as well as those galaxies that have completed an orbit around the system and are currently outside the virial radius, referred to as backsplash galaxies.
