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…
Unprecedented Constraints on Gas Flows at High Redshift Using Deep JWST/NIRSpec Observations from the LyC22, EXCELS, and AURORA Surveys
Emily Kehoe, Alice E. Shapley, Adam C. Carnall +25
We investigate how low-ionization gas flows in typical star-forming galaxies at depend on galaxy intrinsic properties and viewing angle. For this analysis we use JWST/NIRS…
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…
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…
Ly visibility from z = 4.5 to 11 in the UDS field: Evidence for a high neutral hydrogen fraction and small ionized bubbles at z 7
L. Napolitano, L. Pentericci, M. Dickinson +28
The resonant scattering nature of Ly photons interacting with neutral hydrogen makes Ly emitters (LAEs) robust tracers of the intergalactic neutral hydrogen fraction, and t…
