A stellar bar hidden in an extreme gas-rich disk galaxy at z=4.055

Leindert A. Boogaard, Luca Costantin, Thor Tepper-García +14

The classical picture for the formation of stellar bars -- key dynamical drivers of the evolution of galaxies -- is through secular evolution of instability in gas poor, stellar-do…

MIRI spectrophotometry of GN-z11: Detection and nature of an optical red continuum component

A. Crespo Gómez, L. Colina, P. G. Pérez-González +16

We present new MIRI F560W, F770W and F1000W imaging of GN-z11, extending the previous rest-frame coverage from 0.38 to 0.86m. We report significant detections (14) in the F…

RIOJA. A Clumpy Galaxy Assembly at Redshift 6.81 Revealed by JWST

Ken Mawatari, Luca Costantin, Mitsutaka Usui +21

Spatially resolved multi-wavelength analysis is essential to study galaxy formation and evolution. A UV-bright galaxy COS-2987030247 at is one of the Rosetta Stones in t…

Resolving the dusty star-forming galaxy GN20 at z=4.055 with NOEMA and JWST: A similar distribution of stars, gas and dust despite distinct apparent profiles

Leindert A. Boogaard, Fabian Walter, Axel Weiss +8

We present high-resolution (0.13"-0.23") NOEMA observations of the dust continuum emission at 1.1 mm (rest-frame 220 micron) and JWST/NIRCam and MIRI imaging of the z=4.055 starbur…

ELPIS: Accelerated metal and dust enrichment in a proto-cluster core at

Hideki Umehata, Yoichi Tamura, Yoshinobu Fudamoto +17

We present a study of the metal, dust, and molecular gas content in galaxies within the A2744-z7p9OD proto-cluster at z ~ 7.88. We focus on two galaxy groups, the Quintet and the C…

MIDIS: MIRI uncovers Virgil, the first Little Red Dot with clear detection of its host galaxy at z ~ 6.6

Edoardo Iani, Pierluigi Rinaldi, Karina I. Caputi +24

We present Virgil, a MIRI extremely red object (MERO) detected with the F1000W filter as part of the MIRI Deep Imaging Survey (MIDIS) observations of the Hubble Ultra Deep Field (H…
