GOALS-JWST: Resolved multi-phase molecular gas in IRAS 20551-4250 using JWST and ALMA

D. Kakkad, Y. Song, T. S. -Y. Lai +24

Studying the content and distribution of molecular gas provides key insights into how feedback from Active Galactic Nuclei (AGN) and star formation influences galaxy evolution, sin…

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…

JWST Observations of Starbursts: PAHs Closely Trace the Cool Phase of M82's Galactic Wind

Sebastian Lopez, Colton Ring, Adam K. Leroy +30

Stellar feedback drives multiphase gas outflows from starburst galaxies, but the interpretation of dust emission in these winds remains uncertain. To investigate this, we analyze n…

Spatially Resolved Star Formation relations in local LIRGs along the complete merger sequence

M. Sánchez-García, T. Díaz-Santos, L. Barcos-Muñoz +25

We investigate the properties of the interstellar medium (ISM) at ~100 pc scales in a sample of 27 nearby luminous infrared galaxies (LIRGs) spanning the entire merger sequence. In…

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…

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…
