Dissecting the Obscured Core of GN20: an Active Galactic Nucleus Outshone by Young Stars
M. Hamed, L. Colina, P. G. Pérez-González +17
We investigate the relative contributions of star formation and AGN activity to the total energy budget of GN20, one of the most luminous dusty star-forming galaxies known at …
A stellar bar hidden in an extreme gas-rich disk galaxy at z=4.055
Leindert A. Boogaard, Luca Costantin, Thor Tepper-GarcÃa +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…
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.…
JWST Observations of Starbursts: Molecular Hydrogen Excitation and Disequilibrium in M82
Sara E. Duval, J. D. T. Smith, Alberto D. Bolatto +24
Emission from the pure rotational transitions of H traces warm molecular gas, providing insight into its temperature distribution and local heating conditions. We have extended…
JWST Observations of Starbursts: Dust Processing in the M82 Superwind
Serena A. Cronin, Alberto D. Bolatto, Helena M. Richie +39
We present JWST MIRI and NIRCam imaging of the inner ~5 kpc of the M82 superwind at 0.05-0.375'' (~0.9-6.5 pc) resolution. Targeted filters probe emission from polycyclic aromatic…
