[CII] as a global cold gas tracer in novel hydrodynamical simulations
Valentina P. Miranda, Patricia B. Tissera, Jorge González-López +1
[CII] emission is a powerful tool for studying the gas content in galaxies, especially at early stages of evolution. Given its low excitation potential, the [CII] 158 μm line is th…
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…
On the origin of counterrotating stellar disks in TNG50. I
M. C. Bugueño, Facundo A. Gómez, Arianna Dolfi +1
Understanding galaxy evolution is key to explaining the structures we observe in the present-day Universe. Counterrotating stellar disks (CRDs), i.e. co-spatial stellar disks rotat…
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…
