The mass-metallicity relation of bulges
Ignacio Muñoz-Escobar, Patricia B. Tissera, Jenny Gonzalez-Jara +4
Context. Bulges, located at the central regions of galaxies, are complex structures, expected to be shaped by the physical processes involved in the assembly history of their host…
Metal-loaded outflows in sub-Milky Way galaxies in the CIELO simulations
Valentina P. Miranda, Patricia B. Tissera, Emanuel Sillero +5
Supernova (SN) feedback-driven galactic outflows are a key physical process that contributes to the baryon cycle by regulating the star formation activity, reducing the amount of m…
Insight into the physical processes that shape the metallicity profiles in galaxies
Brian Tapia-Contreras, Patricia B. Tissera, Emanuel Sillero +6
The distribution of chemical elements in the star-forming regions can store information on the chemical enrichment history of the galaxies. Negative metallicity gradients are expec…
The CIELO Project: The Chemo-dynamical properties of gaLaxies and the cosmic web
Patricia Tissera, Lucas Bignone, Jenny Gonzalez-Jara +13
The CIELO project introduces a novel set of chemo-dynamical zoom-in simulations designed to simultaneously resolve galaxies and their nearby environments. The initial conditions in…
Unveiling the formation channels of stellar halos through their chemical fingerprints
Jenny Gonzalez-Jara, Patricia B. Tissera, Antonela Monachesi +6
Stellar halos around galaxies contain key information about their formation and assembly history. Using simulations, we can trace the origins of different stellar populations in th…
The role of accreted and in situ populations in shaping the stellar halos of low-mass galaxies
Elisa A. Tau, Antonela Monachesi, Facundo A. Gomez +7
The stellar halos of dwarf galaxies are becoming an object of interest in the extragalactic community due to their detection in some recent observations. Additionally, new cosmolog…
