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…
JWST PRIMER: Post-starburst galaxies dominate the low-mass quiescent galaxy population since z~2
Thomas de Lisle, David T. Maltby, Omar Almaini +10
We present the evolution of the stellar mass functions for photometrically selected star-forming, passive and post-starburst galaxies, based on JWST PRIMER observations of the Ultr…
No hidden monsters: Probing recently-quenched galaxies for obscured AGN with JWST-PRIMER MIRI and NIRCam
Guillaume Hewitt, Omar Almaini, David Maltby +13
We investigate the role of obscured active galactic nuclei (AGN) in recently quenched post-starburst galaxies (PSBs), using a sample of 65 photometrically selected PSBs in the PRIM…
The multiwavelength structure of post-starburst galaxies at 0.5 < z < 3 with JWST PRIMER: compact morphologies and residual disturbances
David T. Maltby, Omar Almaini, Vivienne Wild +9
We investigate the multi-wavelength structure of recently quenched post-starburst (PSB) galaxies at 0.5 < z < 3, using photometrically selected samples from the Ultra Deep Survey (…
The AURORA Survey: High-Redshift Empirical Metallicity Calibrations from Electron Temperature Measurements at z=2-10
Ryan L. Sanders, Alice E. Shapley, Michael W. Topping +29
We present detections of auroral emission lines of [OIII], [OII], [SIII], and [SII] in deep JWST/NIRSpec spectroscopy for 41 star-forming galaxies at from the AURORA su…
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…
