LYRA: The formation and growth of nuclear star clusters in dwarf galaxies
Joaquin Sureda, Azadeh Fattahi, Sownak Bose +5
Nuclear star clusters (NSCs) are dense massive star clusters ubiquitous in galactic centres across various mass regimes, present in up to per cent of dwarf galaxies with $…
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…
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…
The JWST/NIRSpec view of the nuclear region in the prototypical merging galaxy NGC 6240
Matteo Ceci, Giovanni Cresci, Santiago Arribas +9
Merger events are thought to be an important phase in the assembly of massive galaxies. At the same time, Active Galactic Nuclei (AGN) play a fundamental role in the evolution of t…
JWST/NIRSpec insights into the circumnuclear region of Arp 220: A detailed kinematic study
L. Ulivi, M. Perna, I. Lamperti +13
The study of starburst and active galactic nuclei (AGN) feedback is crucial for understanding the regulation of star formation and the evolution of galaxies across cosmic time. Arp…
Young Stellar Objects in NGC 346: A JWST NIRCam/MIRI Imaging Survey
Nolan Habel, Conor Nally, Laura Lenkic +17
We present a JWST imaging survey with NIRCam and MIRI of NGC 346, the brightest star-forming region in the Small Magellanic Cloud (SMC). By combining aperture and point spread func…
Growing a nuclear star cluster from star formation and cluster mergers: The JWST NIRSpec view of NGC 4654
Katja Fahrion, Torsten Böker, Michele Perna +10
We present a detailed study of the centre of NGC4654, a Milky Way-like spiral galaxy in the Virgo cluster that has been reported to host a double stellar nucleus, thus promising a…
No evidence of AGN features in the nuclei of Arp 220 from JWST/NIRSpec IFS
Michele Perna, Santiago Arribas, Isabella Lamperti +12
Arp 220 is the nearest ULIRG; it shows evidence of 100 pc-scale molecular outflows likely connected with galaxy-scale outflows traced by ionised and neutral gas. The two highly obs…
The hierarchical formation of 30 Doradus as seen by JWST
K. Fahrion, G. De Marchi
The 30 Doradus region in the Large Magellanic Cloud (LMC) is the most energetic star-forming region in the Local Group. It is powered by the feedback from the massive stars in R136…
Extending the extinction law in 30 Doradus to the infrared with JWST
Katja Fahrion, Guido De Marchi
We measure the extinction law in the 30 Dor star formation region in the Large Magellanic Cloud using Early Release Observations taken with Near-Infrared Camera (NIRCam) onboard th…
Discovery of dusty sub-solar mass young stellar objects in NGC 346 with JWST/NIRCam
Olivia C. Jones, Conor Nally, Nolan Habel +23
JWST observations of NGC 346, a star-forming region in the metal-poor Small Magellanic Cloud, reveal a substantial population of sub-solar mass young stellar objects (YSOs) with IR…
Evaluating the feasibility of interpretable machine learning for globular cluster detection
Dominik Dold, Katja Fahrion
Extragalactic globular clusters (GCs) are important tracers of galaxy formation and evolution. Obtaining GC catalogues from photometric data involves several steps which will likel…
