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: A spectroscopic investigation of the ionizing properties of star-forming galaxies at 1<z<8

R. Begley, R. J. McLure, F. Cullen +11

Charting the Epoch of Reionization demands robust assessments of what drives the production of ionizing photons in high-redshift star-forming galaxies (SFGs), and requires better p…
