Reconstructing chemical enrichment pathways in disc galaxies: A phylogenetic approach
Brian Tapia-Contreras, Patricia B. Tissera, Emanuel Sillero +11
Phylogenetic methods, traditionally used in biology to trace the evolutionary relationships among species, are emerging as a powerful framework to reconstruct evolutionary processe…
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…
Aligned and misaligned metallicity gradients in young stars and star-forming regions in the EAGLE discs
Isha Shailesh, Patricia B. Tissera, Emanuel Sillero
Disc galaxies exhibit radial metallicity gradients in both their stellar and gaseous components. The star-forming gas (SFG) in HII regions and young stars (YSs) trace the recent ev…
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…
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…
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…
