Distance and reddening of the Local Group dwarf irregular galaxy NGC 6822

open access: yes, 2012
On the basis of a new photometric analysis of the Local Group dwarf irregular galaxy NCG 6822 based on observations obtained with the Advanced Camera for Surveys onboard the Hubble Space Telescope, we have obtained a new estimate of the extinction of two

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

open access: yesThe 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.

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

open access: yesThe 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,

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

open access: yesThe 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 ...

Galaxy Ultraviolet Legacy Project: Survey Description and First Insights into NGC 4449 Recent History of Star Formation

open access: yesThe Astrophysical Journal
The Galaxy UV Legacy Project (GULP) is a Cycle 28 Treasury program with the Hubble Space Telescope designed to characterize resolved massive stars, OB associations, and young star clusters in 26 nearby star-forming galaxies. Utilizing the Advanced Camera

Emergence of the Galaxy Morphology–Star Formation Activity–Clustercentric Radius Relations in Galaxy Clusters

open access: yesThe Astrophysical Journal
We investigate when and how the relations of galaxy morphology and star-forming activity with clustercentric radius become evident in galaxy clusters. We identify 162 galaxy clusters with total mass ${{M}}_{\mathrm{tot}}^{\mathrm{cl}}\gt 5\times {10}^{13}
