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…
Angular momentum evolution in the CIELO simulations. I. Temporal evolution of gas-stellar misalignments and baryonic merger timing
Catalina Casanueva-Villarreal, Patricia B. Tissera, Nelson Padilla +4
Gas-stellar kinematic misalignments trace how galaxies assemble and reorient their angular momentum. Although well documented locally, their continuous evolution remains largely un…
The heartbeat of stellar halos: Insights from the stellar halo mass-metallicity relation
Jenny Gonzalez-Jara, Patricia B. Tissera, Antonela Monachesi +5
This work investigates the presence and evolution of the MZhR from redshift z=3.5 to z=0, and identifies when galaxies settle on the present-day MZhR. We used central galaxies with…
Chemical enrichment in LINERs from MaNGA. II. Characterizing the shape of their radial metallicity gradients
Borja Pérez-DÃaz, José M. VÃlchez, Enrique Pérez Montero +3
Chemical abundance radial gradients provide key information on how the processes that affect chemical enrichment of the gas-phase interstellar medium (ISM) act at different galaxy…
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…
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…
