An Investigation Into The Selection and Colors of Little Red Dots and Active Galactic Nuclei
Kevin N. Hainline, Roberto Maiolino, Ignas Juodzbalis +25
Recently, a large number of compact sources at with blue UV slopes and extremely red rest-frame optical slopes have been found in James Webb Space Telescope (JWST) extragal…
Not Just a Dot: the complex UV morphology and underlying properties of Little Red Dots
P. Rinaldi, N. Bonaventura, G. H. Rieke +31
We analyze 99 photometrically selected Little Red Dots (LRDs) at in the GOODS fields, leveraging ultra-deep JADES NIRCam short-wavelength (SW) data. We examine the…
SMILES: Potentially Higher Ionizing Photon Production Efficiency in Overdense Regions
Yongda Zhu, Stacey Alberts, Jianwei Lyu +14
The topology of reionization and the environments where galaxies efficiently produce ionizing photons are key open questions. For the first time, we investigate the trend between i…
Extended hot dust emission around the earliest massive quiescent galaxy
Zhiyuan Ji, Christina C. Williams, George H. Rieke +14
A major unsolved problem in galaxy evolution is the early appearance of massive quiescent galaxies that no longer actively form stars only billion years after the Big Ban…
The eventful life of a luminous galaxy at z = 14: metal enrichment, feedback, and low gas fraction?
Stefano Carniani, Francesco D'Eugenio, Xihan Ji +25
JADES-GS-z14-0 is the most distant spectroscopically confirmed galaxy yet, at . With a UV magnitude of -20.81, it is one of the most luminous galaxies at cosmic dawn and its…
A Systematic Search for Galaxies with Extended Emission Line and Potential Outflows in JADES Medium-Band Images
Yongda Zhu, Marcia J. Rieke, Zhiyuan Ji +20
For the first time, we present a systematic search for galaxies with extended emission line and potential outflow features using \textit{JWST} medium-band images in the GOODS-S fie…
No evidence for a significant evolution of - relation in massive galaxies up to z4
Yang Sun, Jianwei Lyu, George H. Rieke +19
Over the past two decades, tight correlations between black hole masses () and their host galaxy properties have been firmly established for massive galaxies ($\log(M_*/…
JWST/NIRSpec WIDE survey: a z=4.6 low-mass star-forming galaxy hosting a jet-driven shock with low ionisation and solar metallicity
Francesco D'Eugenio, Roberto Maiolino, Vijay H. Mahatma +14
We present NIRSpec/MSA observations from the JWST large-area survey WIDE, targeting the rest-frame UV-optical spectrum of Ulema, a radio-AGN host at redshift z=4.6348. The low-reso…
Witnessing the onset of reionisation via Lyman- emission at redshift 13
Joris Witstok, Peter Jakobsen, Roberto Maiolino +34
$\require{mediawiki-texvc}$Cosmic Reionisation commenced when ultraviolet (UV) radiation produced in the first galaxies began illuminating the cold, neutral gas that filled the pri…
JADES: Spectroscopic Confirmation and Proper Motion for a T-Dwarf at 2 Kiloparsecs
Kevin N. Hainline, Francesco D'Eugenio, Fengwu Sun +15
Large area observations of extragalactic deep fields with the James Webb Space Telescope (JWST) have provided a wealth of candidate low-mass L- and T-class brown dwarfs. The existe…
SMILES Initial Data Release: Unveiling the Obscured Universe with MIRI Multi-band Imaging
Stacey Alberts, Jianwei Lyu, Irene Shivaei +12
The James Webb Space Telescope (JWST) is revolutionizing our view of the Universe through unprecedented sensitivity and resolution in the infrared, with some of the largest gains r…
Spectroscopic confirmation of two luminous galaxies at
Stefano Carniani, Kevin Hainline, Francesco D'Eugenio +42
