What Does the LMC Look Like? It Depends on [M/H] and Age

The Astrophysical Journal
We offer a new way to look at the LMC through stellar mono-abundance and mono-age mono-abundance maps. These maps are based on ≳500,000 member stars with estimates of [M/H] ( σ _[M/H]  ~ 0.17) and age $({\sigma }_{{\rm{log}}\tau }\unicode{x0007E}0.15$ ),

Detection of Metal Enrichment by SN 2011jm in NGC 4809

The Astrophysical Journal Letters
Cosmic metals are believed to originate from stellar and supernovae (SNe) nucleosynthesis, dispersed into the interstellar medium (ISM) through stellar winds and supernova explosions.

Mock Observations: Morphological Analysis of Galaxies in TNG100 Simulations

The Astrophysical Journal Supplement Series
In this study, we investigate the morphology of galaxies in the TNG100 simulation by applying mock observation techniques and compare the results with the observational data from the Sloan Digital Sky Survey (SDSS).
