A clear detection of proper motion confirms that the claimed galaxy candidate, "Capotauro'', is a Y-type brown dwarf
F. -Y. F. Liu, D. J. McLeod, B. J. Sutlieff +13
The compact red source ``Capotauro'', discovered in deep JWST imaging in 2025, has been suggested as a possible galaxy candidate at redshift on account of its extreme N…
The JWST EXCELS survey: Outflows in 1.5 < z < 5 quiescent and recently quenched galaxies are likely relics from episodic AGN activity
Elizabeth Taylor, Adam C. Carnall, David Maltby +24
We investigate the presence and origin of neutral gas outflows and inflows in 13 post-starburst (PSB) and quiescent galaxies at redshifts 1.8 z 4.6, using JWST NIRSpe…
The JWST EXCELS survey: The ages and abundances of massive quiescent galaxies show that downsizing was already in place by
Ho-Hin Leung, Adam C. Carnall, Elizabeth Taylor +21
We present deep, medium-resolution m JWST/NIRSpec spectroscopy for 14 quiescent galaxies at with , obtained as part of…
A search for the first galaxies across deg of JWST imaging: new evidence for a rapid decline in star-formation activity at
D. J. McLeod, J. S. Dunlop, R. J. McLure +20
We present a new determination of the evolving galaxy UV luminosity function (LF) over the extreme redshift range , based on a wide-area search of 0.6 deg of JW…
Spectroscopic confirmation of a large and luminous galaxy with weak emission lines at
Callum T. Donnan, Derek J. McLeod, Ross J. McLure +15
We present JWST/NIRSpec PRISM observations of a robust galaxy candidate at , selected from pure-parallel NIRCam imaging; PAN-z14-1. The NIRSpec spectrum allows confirmat…
The JWST EXCELS Survey: gas-phase metallicity evolution at 2 < z < 8
T. M. Stanton, F. Cullen, A. C. Carnall +15
We present an analysis of the gas-phase mass-metallicity relationship (MZR) and fundamental metallicity relationship (FMR) for star-forming galaxies at from the JW…
