Rapid, out of equilibrium metal enrichment indicated by a flat mass-metallicity relation at z~6 from NIRCam grism spectroscopy
Gauri Kotiwale, Jorryt Matthee, Daichi Kashino +17
We aim to characterise the mass-metallicity relation (MZR) and the 3D correlation between stellar mass, metallicity and star-formation rate (SFR) known as the fundamental metallici…
The JWST Emission Line Survey (JELS): The sizes and merger fraction of star-forming galaxies during the Epoch of Reionization
H. M. O. Stephenson, J. P. Stott, C. A. Pirie +18
We used observations from the JWST Emission Line Survey (JELS) to measure the half-light radii () of 23 H-emitting star-forming (SF) galaxies at in the PRIMER/CO…
The JWST Emission Line Survey (JELS): An untargeted search for H emission line galaxies at and their physical properties
C. A. Pirie, P. N. Best, K. J. Duncan +19
We present the first results of the JWST Emission Line Survey (JELS). Utilising the first NIRCam narrow-band imaging at 4.7m, over 63 arcmin in the PRIMER/COSMOS field, w…
The JWST Emission Line Survey (JELS): Extending rest-optical narrow-band emission line selection into the Epoch of Reionization
K. J. Duncan, D. J. McLeod, P. N. Best +20
We present the JWST Emission Line Survey (JELS), a JWST imaging programme exploiting the wavelength coverage and sensitivity of NIRCam to extend narrow-band rest-optical emission l…
A "Black Hole Star" Reveals the Remarkable Gas-Enshrouded Hearts of the Little Red Dots
Rohan P. Naidu, Jorryt Matthee, Harley Katz +48
The physical processes that led to the formation of billion solar mass black holes within the first 700 million years of cosmic time remain a puzzle. Several theoretical scenarios…
An unambiguous AGN and a Balmer break in an Ultraluminous Little Red Dot at z=4.47 from Ultradeep UNCOVER and All the Little Things Spectroscopy
Ivo Labbe, Jenny E. Greene, Jorryt Matthee +37
We present a detailed exploration of the most optically-luminous Little Red Dot (erg/s, erg/s, F444W=22AB) found to date. Located in the Abell 2744 fi…
