JWST NIRCam and MIRI Reveal the Dust-Producing AGB Population of NGC 6822

Conor Nally, Olivia C. Jones, Laura Lenkić +9

The paper presents a JWST NIRCam and MIRI photometric catalogue of the dwarf galaxy NGC 6822, identifies dust‑producing asymptotic giant branch (AGB) stars, and quantifies their du…

JWST/MIRI-MRS view of the metal-poor galaxy CGCG 007-025: the spatial location of PAHs and very highly ionized gas

Macarena G. del Valle-Espinosa, Matilde Mingozzi, Bethan James +16

Polycyclic Aromatic Hydrocarbons (PAHs) are key diagnostics of the physical conditions in the interstellar medium and are widely used to trace star formation in the mid-infrared (m…

A Mid-Infrared Spectroscopic Study of Young Stellar Objects in the SMC Region NGC 346: JWST Detects Dust, Accretion, Ices and Outflows

Nolan Habel, Omnarayani Nayak, Patrick J. Kavanagh +13

We present mid-infrared spectroscopic observations of intermediate- to high-mass young stellar objects (YSOs) in the low-metallicity star-forming region NGC 346 located within the…

The Interstellar Medium in I Zw 18 seen with JWST/MIRI: II. Warm Molecular Hydrogen and Warm Dust

L. K. Hunt, B. T. Draine, M. G. Navarro +16

We present JWST/MIRI spectra from the Medium-Resolution Spectrometer of IZw18, a nearby dwarf galaxy with a metallicity of % Solar. Here, we investigate warm molecular hydr…

First detection of ices in intermediate-mass young stellar objects beyond the Milky Way

Guido De Marchi, Nolan Habel, Margaret Meixner +15

Using NIRSpec on JWST, we studied a sample of 15 intermediate-mass (1.8-4.1 Msun) young stellar objects (YSOs) previously identified with MIRI photometry in the low-metallicity NGC…

The Interstellar Medium in IZw18 seen with JWST/MIRI: I. Highly Ionized Gas

L. K. Hunt, A. Aloisi, M. G. Navarro +19

We present JWST/MIRI spectra from the Medium-Resolution Spectrometer of IZw18, a nearby dwarf galaxy with a metallicity of 3% Solar. Its proximity enables a detailed study of…
