MICONIC: The spatial relationship between star formation and the AGN in Centaurus A revealed by JWST/MIRI
O. C. Jones, M. L. Jones, D. Dicken +21
Centaurus A (Cen A), the nearest active radio galaxy, hosts a warped dust disc formed in a gas-rich merger. We present JWST/MIRI imaging in three filters, F560W, F770W, and F1130W,…
JOYS: A JWST/MIRI survey of the evolution of H winds and jets from low-mass protostars
L. Francis, Ł. Tychoniec, E. F. van Dishoeck +20
Protostellar outflows display wide-angle winds and collimated jets, the magnetocentrifugal launching of which enables accretion onto the protostar. The majority of the outflow mass…

R. Devaraj, E. F. van Dishoeck, T. P. Ray +12
This study characterized the physical and kinematic properties within the innermost 500 au region of the L1527 bipolar outflow, a class 0/I low-mass protostar using JWST MIRI/MRS s…
Evidence for SiO cloud nucleation in the rogue planet PSO J318
P. Mollière, H. Kühnle, E. C. Matthews +25
Silicate clouds are known to significantly impact the spectra of late L-type brown dwarfs, with observable absorption features at ~ 10 micron. JWST has reopened our window to the m…
Detection of CO, CO, and HO in the atmosphere of the warm sub-Saturn HAT-P-12b
N. Crouzet, B. Edwards, T. Konings +29
The chemical composition of warm gas giant exoplanet atmospheres (with Teq < 1000 K) is not well known due to the lack of observational constraints. HAT-P-12 b is a warm, sub-Satur…
JWST Observations of Young protoStars (JOYS): overview of program and early results
E. F. van Dishoeck, Ł. Tychoniec, W. R. M. Rocha +34
The embedded phase is a crucial period in the development of a young star. Mid-IR observations, now possible with JWST with unprecedented sensitivity, spectral resolution and sharp…

L. Hermosa Muñoz, A. Alonso-Herrero, A. Labiano +19
As part of the guaranteed time observations program Mid-Infrared Characterization Of Nearby Iconic galaxy Centers (MICONIC), we used the medium-resolution spectrometer (MRS) of the…
JWST Observations of Young protoStars (JOYS). Overview of gaseous molecular emission and absorption in low-mass protostars
M. L. van Gelder, L. Francis, E. F. van Dishoeck +17
The MIRI-MRS instrument onboard JWST allows for probing the molecular gas composition at mid-IR wavelengths at unprecedented resolution and sensitivity. It is important to study th…
JWST Observations of Young protoStars (JOYS). HH 211: the textbook case of a protostellar jet and outflow
A. Caratti o Garatti, T. P. Ray, P. J. Kavanagh +22
We use the James Webb Space Telescope (JWST) and its Mid-Infrared Instrument (MIRI) (5-28 um), to study the embedded HH 211 flow. We map a 0.95'x0.22' region, covering the full ext…
Abundant hydrocarbons in the disk around a very-low-mass star
A. M. Arabhavi, I. Kamp, Th. Henning +40
Very low-mass stars (those <0.3 solar masses) host orbiting terrestrial planets more frequently than other types of stars, but the compositions of those planets are largely unknown…
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…
Radio outburst from a massive (proto)star. III. Unveiling the bipolarity of the radio jet from S255IR NIRS3
R. Cesaroni, L. Moscadelli, A. Caratti o Garatti +6
We report new Very Large Array high-resolution observations of the radio jet from the outbursting high-mass star S255IR~NIRS3. The images at 6, 10, and 22.2 GHz confirm the existen…
JWST MIRI Imager Observations of Supernova SN 1987A
P. Bouchet, R. Gastaud, A. Coulais +31
There exist very few mid-infrared (IR) observations of supernovae (SNe) in general. Therefore, SN 1987A, the closest visible SN in 400 years, gives us the opportunity to explore th…
JOYS: MIRI/MRS spectroscopy of gas-phase molecules from the high-mass star-forming region IRAS 23385+6053
L. Francis, M. L. van Gelder, E. F. van Dishoeck +16
Space-based mid-IR spectroscopy provides tracers of warm gas in star-forming regions that are inaccessible from the ground. Past mid-IR spectra of bright high-mass protostars in th…
JWST Observations of Young protoStars (JOYS+): Detection of icy complex organic molecules and ions. I. CH, SO, HCOO, OCN, HCO, HCOOH, CHCHOH, CHCHO, CHOCHO, CHCOOH
W. R. M. Rocha, E. F. van Dishoeck, M. E. Ressler +23
Complex organic molecules (COMs) detected in the gas phase are thought to be mostly formed on icy grains, but no unambiguous detection of icy COMs larger than CH3OH has been report…
Clumpy star formation and an obscured nuclear starburst in the luminous dusty z=4 galaxy GN20 seen by MIRI/JWST
A. Bik, J. Álvarez-Márquez, L. Colina +28
Dusty star-forming galaxies emit most of their light at far-IR to mm wavelengths as their star formation is highly obscured. Far-IR and mm observations have revealed their dust, ne…
