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-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…

MICONIC: The multiphase circumnuclear region of Centaurus A as seen with JWST/MIRI MRS observations. I. Spectral inventory and properties of the warm molecular disk

L. Evangelista, P. Guillard, J. Martin +21

Supermassive black holes power Active Galactic Nuclei (AGN), injecting energy that regulates accretion and shapes host galaxies. We investigate the morphology, excitation, and kine…

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…

Spatially resolved metallicity and ionization in the merging system Gz9p3 at z=9.3

Arjan Bik, Javier Álvarez-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…

MIDIS: Strong H+[OIII] Line Emitters at

Thomas R. Greve, Steven Gillman, Pierluigi Rinaldi +24

We present a search for strong H+[O III] emitters at in the HUDF using ultra-deep JWST/MIRI F560W imaging from the MIDIS survey. Three galaxies are identified via…
