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}

COSMIC-L: A Photometric Catalog of Observed Stars in the Large Magellanic Cloud

The Astrophysical Journal Supplement Series
The Magellanic Clouds are two nearby dwarf irregular galaxies, the study of which can help us in understanding galaxy and stellar evolution. In particular, the Large Magellanic Cloud, the larger one, contains approximately 30 billion stars at various ...

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 ...
