Abstract: The CIELO Project (Chemo-dynamIcal propertiEs of gaLaxies and the cOsmic web) is a new suite of high-resolution zoom-in simulations designed to explore the coupled chemical and dynamical evolution of galaxies within their cosmic-web environments. Its initial conditions sample a wide range of large-scale structures—including Local Group analogues, filaments, walls, and voids—enabling a systematic study of how environment shapes galaxy assembly.
The current sample contains 54 central galaxies with stellar masses between 10⁸–10¹¹ M⊙. These systems reproduce key scaling relations—mass–halo mass, mass–size, Tully–Fisher, and both gas-phase and stellar mass–metallicity relations—demonstrating realistic regulation of star formation and feedback. The simulations reveal clear secondary trends: morphology, size, star-formation rate, and compactness modulate galaxy metallicities and structural evolution.
I will talk about the some of the projects and results we are working on with these simulations
