The evolved asymptotic giant branch stars in the central bar of the dwarf irregular galaxy NGC 6822

, 2006
Images of ${\it JHK}$ and ${\it gi}$ obtained with the Canada-France-Hawaii Telescope are used to investigate the stellar contents of the resolved asymptotic giant branch (AGB) population in the area of $3\farcm6\times6\farcm3$ on the central bar of the ...

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 inclination of the dwarf irregular galaxy Holmberg II

, 2014
We provide constraints on the inclination angle of the H\,{\sc i} disk of the dwarf irregular galaxy Holmberg II (Ho II) from stability analysis of the outer gaseous disk. We point out that a mean inclination angle of 27 degrees and thus a flat circular velocity of ~60 km/s, is required to have a level of gravitational stability similar to that found ...

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

The 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}

Probing the Relationship Between Early Star Formation and CO in the Dwarf Irregular Galaxy WLM with JWST

The Astronomical Journal
Wolf–Lundmark–Melotte (WLM) is a Local Group dwarf irregular (dIrr) galaxy with a metallicity 13% of solar. At 1 Mpc, the relative isolation of WLM provides a unique opportunity to investigate the internal mechanisms of star formation at low ...
