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…
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…
JWST Reveals Two Overmassive Black Hole Candidates in Dwarf Galaxies at z 0.7: Pushing Black Hole Searches into the Dwarf-Galaxy Regime
E. Iani, P. Rinaldi, A. Torralba +35
We report the discovery and characterization of two compact galaxies, Pelias and Neleus, at z ~ 0.71 and z ~ 0.75, identified in MACS J0416.1-2403 and GOODS-North. Both exhibit unu…
Little Red Dots: One Photometric Tag Concealing Diverse Spectroscopic Flavors of Massive Star Formation and Black Hole Activity
Pablo G. Pérez-González, Guillermo Barro, Stefano Carniani +62
We compile JWST/NIRSpec prism and MIRI data for 249 Little Red Dots (LRDs) at 2.3<z<9.3, forming a representative spectroscopic subset of NIRCam-selected LRDs. We derive a median s…
The Ly and Continuum Origins Survey. III. Investigating the Link between Galaxy Morphology, Merger Properties and LyC Escape
Alexandra Le Reste, Anne E. Jaskot, Jordanne Brazie +20
Characterizing the mechanisms and galaxy properties conducive to the emission and escape of ionizing (LyC) emission is necessary to accurately model the Epoch of Reionization, and…
The rise of the galactic empire: luminosity functions at and estimated with the MIDISNGDEEP ultra-deep JWST/NIRCam dataset
Pablo G. Pérez-González, Göran Ãstlin, Luca Costantin +39
We present a sample of six F200W and three F277W dropout sources identified as galaxy candidates using the deepest JWST/NIRCam data to date (5 depths mag a…
