Local metallicity in simulated galaxies

In the last decade, integral field spectroscopy has expanded our understanding of chemical evolution of galaxies, giving evidence of a radial gradient of gas-phase metallicity. In this work, we use the state-of-art hydrodynamical simulation EAGLE to study the resolved, local properties of galaxies....

En la última década, la espectroscopia de campo integrado ha expandido nuestra comprensión de la evolución química de las galaxias, dando evidencia de un gradiente radial de la metalicidad de la fase gaseosa. En este trabajo, usamos la simulación cosmológica hidrodinámica EAGLE para estudiar las propiedades localmente resueltas de las galaxias. Mostramos que la metalicidad local del gas correlaciona con la densidad superficial de masa estelar y anticorrelaciona con la acreción de gas. Los perfiles de metalicidad resueltos actúan como buenos estimadores de la acreción de gas, y pueden ser usados para entender los cambios en el enriquecimiento químico de las galaxias.

description In the last decade, integral field spectroscopy has expanded our understanding of chemical evolution of galaxies, giving evidence of a radial gradient of gas-phase metallicity. In this work, we use the state-of-art hydrodynamical simulation EAGLE to study the resolved, local properties of galaxies. We show that the local gas metallicity correlates with the stellar mass surface density and anti-correlates with the gas accretion. Resolved metallicity profiles acts as a good estimator of gas accretion, and can be used to understand the changes in the chemical enrichment of galaxies.
