Enhancing the performance and capabilities of the MIRI instrument on JWST
S. Kendrew, M. Engesser, K. Rowlands +23
MIRI, the Mid-Infrared Instrument on the James Webb Space Telescope, is the only instrument sensitive to wavelengths longward of 5 um on the observatory. In this regime, MIRI bring…
A new window in time: a mid-infrared slit spectroscopy mode for precision time-series astronomy with JWST/MIRI
Achrene Dyrek, Taylor J. Bell, Pierre-Olivier Lagage +7
The Mid-Infrared Instrument (MIRI) on board the James Webb Space Telescope (JWST) provides Low Resolution Spectroscopy (LRS) over 5-12 um at a resolving power of R ~ 100. To date,…
PRISMS. U37126, a very blue, ISM-naked starburst at z=10.255 with nearly 100% Lyman continuum escape fraction
R. Marques-Chaves, J. Ãlvarez-Márquez, L. Colina +31
We present very deep (~11h) JWST/MIRI low-resolution spectroscopy of the rest-frame optical emission of U37126, a UV-bright (M_UV ~ -20), mildly lensed () galaxy at z…
Investigating the role of turbulence in the interstellar medium in dusty star-forming galaxies using kpc-resolution ALMA dust and gas maps
B. A. Westoby, J. A. Hodge, P. Sharda +29
We present ALMA high-resolution (0.25/2 kpc) CO(5-4) and CO(4-3) observations of three submillimetre-selected dusty galaxies from the ALESS survey.…
Spatially resolved metallicity and ionization in the merging system Gz9p3 at z=9.3
Arjan Bik, Javier Ãlvarez-Márquez, Alejandro Crespo Gómez +26
Studying the interstellar medium (ISM) in merging high-redshift galaxies is crucial for understanding early galaxy assembly, star formation, and black hole growth, predicted by hie…
ALESS--JWST: Dust-driven Morphologies and Hidden Stellar Mass in Sub-millimeter Galaxies
J. Li, E. da Cunha, J. A. Hodge +17
We present JWST/NIRCam and MIRI observations of twelve sub-millimeter galaxies (SMGs) from the ALESS survey, combined with high-resolution () ALMA 870m…
