Comparing phylogenetic trees of stars with spectral graph distances

Theosamuele Signor, Matias Neto, Paula Jofré +9

Phylogenetic trees offer a hierarchical representation of chemical similarities among stars, from which their evolutionary histories can, in principle, be reconstructed. Simulation…

The properties of central stellar knots embedded in galactic bulges of CIELO simulations

Belén Acosta-Tripailao, Patricia B. Tissera, Manuela Zoccali +7

Deeply bound stellar substructures of about 1 kpc at the center of bulges are found in a subset of galaxies from the cosmological chemo-hydrodynamical zoom-in CIELO simulation suit…

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…

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…

Chemical enrichment in LINERs from MaNGA. II. Characterizing the shape of their radial metallicity gradients

Borja Pérez-Díaz, José M. Vílchez, 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 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…

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…

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…
