Discovery of Metal-poor and Distant Pre–Main Sequence Candidates in WLM with JWST
The Astrophysical Journal LettersWe 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 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 ...

The Astrophysical JournalWe 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}

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 ...

The Astronomical JournalWolf–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 ...

Discovery of a Relativistic Stripped-envelope Type Ic-BL Supernova at z = 2.83 with JWST
The Astrophysical Journal LettersWe present James Webb Space Telescope (JWST) NIRCam and NIRSpec observations of a Type Ic supernova (SN Ic) and its host galaxy (JADES-GS+53.13533-27.81457) at z = 2.83. This SN (named SN 2023adta) was identified in deep JWST/NIRCam imaging from the JWST
