Sequential Star-Formation and the Near-Infrared Stellar Populations within N159
Nolan Habel, E. Sabbi, Peter Zeidler +19
We present the first results from a JWST/NIRCam study of the star-forming region N159, one of the richest H II complexes in the Large Magellanic Cloud. This region stretches over $…
A near-IR survey of luminous asymptotic giant branch stars in the satellites and stellar halo of M31
Jess M. Howell, Annette M. N. Ferguson, Olivia C. Jones +5
We investigate the dwarf spheroidal (dSph) satellites and stellar halo of M31 using near-infrared imaging from the Wide-Field Camera on the UKIRT 3.8 m telescope. Our homogeneous a…
The Stellar Population of NGC 346 in the Small Magellanic Cloud with JWST
J. Jaspers, P. Kavanagh, G. De Marchi +13
NGC 346 is a massive star-forming region located at a distance of 62 kpc, in the Small Magellanic Cloud (SMC). Due to its low metallicity (Z 1/5 Z), it is an…
JWST NIRCam and MIRI Reveal the Dust-Producing AGB Population of NGC 6822
Conor Nally, Olivia C. Jones, Laura Lenkić +9
We present a photometric catalogue of the Local Group dwarf galaxy NGC 6822 based on deep JWST observations obtained with the Near-Infrared Camera (NIRCam) and Mid-Infrared Instrum…
The evolution of the mid-infrared spectrum of SN 1987A observed with the JWST/MIRI-MRS
P. J. Kavanagh, M. J. Barlow, C. Fransson +19
Supernova (SN) 1987A provides a unique laboratory for investigating many aspects of SN physics and evolution. An observation at Day 12927 (35.4 yr) since the explosion with the Mid…
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…
Detection of CH3+ in the O-rich planetary nebula NGC 6302
Charmi Bhatt, Jan Cami, Els Peeters +33
Planetary nebulae are sites where ejected stellar material evolves into complex molecules, but the precise physical conditions and chemical routes that govern these processes are u…
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…
Detection of a Deeply Embedded Protocluster Candidate in NGC 602 with JWST
Beena Meena, Peter Zeidler, Elena Sabbi +3
JWST NIRCam and MIRI photometry of NGC 602, a low-metallicity young star cluster in the Small Magellanic Cloud, reveals an extended mid-infrared bright emission feature designated…
The JWST/MIRI view of the planetary nebula NGC 6302 I.: a UV irradiated torus and a hot bubble triggering PAH formation
Mikako Matsuura, Kevin Volk, Patrick Kavanagh +34
NGC 6302 is a spectacular bipolar planetary nebula (PN) whose spectrum exhibits fast outflows and highly ionized emission lines, indicating the presence of a very hot central star…
Investigating silicate, carbon, and water in the diffuse interstellar medium: the first shots from WISCI
S. T. Zeegers, Jonathan P. Marshall, Karl D. Gordon +33
The dusty interstellar medium (ISM) of the Milky Way is distributed in a complex, cloudy structure. It is fundamental to the radiation balance within the Milky Way, provides a reac…
Protoplanetary discs around sun-like stars appear to live longer when the metallicity is low
Guido De Marchi, Giovanna Giardino, Katia Biazzo +17
Previous Hubble Space Telescope (HST) observations of the star-forming cluster NGC 346 in the Small Magellanic Cloud (SMC) had revealed a large population of pre-main sequence (PMS…
Imaging of I Zw 18 by JWST: II. Spatially resolved star formation history
Giacomo Bortolini, Göran Östlin, Nolan Habel +14
The blue compact dwarf galaxy I Zw 18 is one of the most metal-poor () star-forming galaxies in the local Universe. Its evolutionary status has sparked debate w…
Young Stellar Objects in NGC 346: A JWST NIRCam/MIRI Imaging Survey

The Mid-Infrared Instrument (MIRI) aboard the James Webb Space Telescope (JWST) provides the observatory with a huge advance in mid-infrared imaging and spectroscopy covering the w…
Emission lines due to ionizing radiation from a compact object in the remnant of Supernova 1987A
C. Fransson, M. J. Barlow, P. J. Kavanagh +31
The nearby Supernova 1987A was accompanied by a burst of neutrino emission, which indicates that a compact object (a neutron star or black hole) was formed in the explosion. There…
