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 $({\sigma }_{{\rm{log}}\tau }\unicode{x0007E}0.15$ ),

Discovery of Metal-poor and Distant Pre–Main Sequence Candidates in WLM with JWST

The Astrophysical Journal Letters
We present the discovery of 12 metal-poor and ​​​distant pre–main sequence (PMS) candidates in the dwarf irregular galaxy Wolf–Lundmark–Melotte ∼968 kpc away, at a present-day metallicity of [Fe/H] ∼ –0.9.

Measuring Resolved Star Formation Histories from High-precision Color–Magnitude Diagrams with StarFormationHistories.jl

The Astrophysical Journal Supplement Series
Understanding how and when galaxies formed stars over the history of the Universe is fundamental to the study of galaxy evolution. The star formation histories (SFHs) of galaxies in the local Universe can be measured with high precision using deep ...

The JWST Resolved Stellar Populations Early Release Science Program. VIII. The Spatially Resolved Star Formation History of WLM

The Astrophysical Journal
Radial stellar population gradients within dwarf galaxies provide a promising avenue for disentangling the drivers of galaxy evolution, including environment. Within the Local Volume, radial stellar age gradient slopes correlate with interaction history,

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).
