Resolving the ionizing photon budget crisis with JWST/NIRCam HII clumping constraints at z=6

Duncan Austin, Thomas Harvey, Christopher J. Conselice +18

We present a comprehensive study of the ionizing properties of 1721 galaxies at using deep JWST/NIRCam photometric imaging from the NEP, JADES, and PRIMER surveys spann…

Little red dot variability over a century reveals black hole envelope via a giant Einstein cross

Zijian Zhang, Mingyu Li, Masamune Oguri +79

"Little red dots" (LRDs) represent a new population of astronomical objects uncovered by JWST whose nature remains debated. Although many LRDs are suspected as active galactic nucl…

Cloudy with a chance of starshine: Possible photometric signatures of nebular-dominated emission in JADES galaxies

James A. A. Trussler, Alex J. Cameron, Daniel J. Eisenstein +21

The discovery of high-redshift galaxies exhibiting a steep spectral UV downturn potentially indicative of two-photon continuum emission marks a turning point in our search for sign…

JADES-GS-z14-1: A Compact, Faint Galaxy at with Weak Metal Lines from Extremely Deep JWST MIRI, NIRCam, and NIRSpec Observations

Zihao Wu, Daniel J. Eisenstein, Benjamin D. Johnson +29

JWST has shed light on galaxy formation and metal enrichment within 300 Myr of the Big Bang. While luminous galaxies at often show significant [O III]4959, 5007 emissi…

Lonely Little Red Dots: Challenges to the AGN-nature of little red dots through their clustering and spectral energy distributions

María Carranza-Escudero, Christopher J. Conselice, Nathan Adams +31

Observations with the James Webb Space Telescope (JWST) reveal a previously unseen population of compact red objects, known as ``little red dots`` (LRDs). We study a new photometri…

Behind the Spotlight: A systematic assessment of outshining using NIRCam medium-bands in the JADES Origins Field

Thomas Harvey, Christopher J. Conselice, Nathan J. Adams +9

The spatial resolution and sensitivity of JWST's NIRCam instrument has revolutionised our ability to probe the internal structure of early galaxies. By leveraging deep medium-band…

JADES and SAPPHIRES: Galaxy Metamorphosis Amidst a Huge, Luminous Emission-line Region

Francesco D'Eugenio, Jakob M. Helton, Kevin Hainline +32

We report the discovery of a remarkably large and luminous line-emitting nebula extending on either side of the Balmer-break galaxy JADES-GS-518794 at z=5.89, detected with JADES J…

The impact of medium-width bands on the selection, and subsequent luminosity function measurements, of high-z galaxies

N. J. Adams, D. Austin, T. Harvey +7

New, ultra-deep medium-width photometric coverage with JWST's NIRCam instrument provides the potential for much improved photo-z reliability at high redshifts. In this study, we co…

New Methods of Identifying AGN in the Early Universe using Spectroscopy and Photometry in the JWST Era

Flor Arevalo Gonzalez, Titanilla Braun, James Trussler +7

We explore spectroscopic and photometric methods for identifying high-redshift galaxies containing an Active Galactic Nucleus (AGN) with JWST observations. After demonstrating the…
