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…

The formation and evolution of Supermassive disks in IllustrisTNG

Diego Pallero, Gaspar Galaz, Patricia B. Tissera +4

Supermassive disks are outstanding galaxies whose formation and evolution are still poorly understood. They comprise a large variety of objects, ranging from large, low-surface-bri…

Mocking IFU observations and metallicity diagnostics from cosmological simulations

A. Cornejo-Cárdenas, E. Sillero, P. B. Tissera +4

Hydrodynamic simulations are powerful tools for studying galaxy formation. However, it is crucial to test and improve the sub-grid physics underlying these simulations by comparing…

Studying stellar populations in Omega Centauri with phylogenetics

P. Jofré, C. Aguilera-Gómez, P. Villarreal +14

The nature and formation history of our Galaxy's largest and most enigmatic stellar cluster, known as Omega Centauri (ocen) remains debated. Here, we offer a novel approach to dise…

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…
