The AURORA Survey: Determining the Production Mechanism for OI Emission in Star-forming Galaxies at Cosmic Noon

Leonardo Clarke, Alice E. Shapley, Zhiwei Shao +11

We analyze deep JWST/NIRSpec observations of 58 star-forming galaxies at in the AURORA survey to investigate the origin of the permitted OI emission feature.…

The gradual decline of Ly visibility in the CANDELS fields: evidence for the combined effects of galaxy evolution and reionization

L. Napolitano, L. Pentericci, A. Ferrara +35

We investigate the evolution of Ly visibility and the physical properties of Ly emitters (LAEs) across the five CANDELS fields using publicly available JWST/NIRSpec PRISM spe…

Beyond orientation: Evidence for distinct physical regimes among Little Red Dots and Little Blue Dots

L. Barrufet, J. S. Dunlop, M. L. Hamadouche +6

Little Red Dots (LRDs) and Little Blue Dots (LBDs) may represent the same population of compact active galactic nuclei (AGN) observed along different lines of sight. We test this s…

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…

Galaxy clusters in the VIDEO fields: detection and characterisation in the context of MOONRISE

Pierre Galois, Christophe Benoist, Gianluca Castignani +21

We analyse the cluster content of the XMM-LSS and CDFS VIDEO fields which are expected to be partially covered by the upcoming MOONRISE survey. Using AMI…

Massive Galaxies Form Early and Gray: Stellar Assembly and Dust Attenuation at from CAPERS

Katherine Chworowsky, Steven L. Finkelstein, Anthony J. Taylor +27

The stellar mass assembly of massive galaxies in the first few billion years of cosmic history remains a central challenge in galaxy formation. Galaxies with $M_\star \gtrsim 10^{1…

Little Red Dots: One Photometric Tag Concealing Diverse Spectroscopic Flavors of Massive Star Formation and Black Hole Activity

Pablo G. Pérez-González, Guillermo Barro, Stefano Carniani +61

We compile JWST/NIRSpec prism and MIRI data for 249 Little Red Dots (LRDs) at 2.3<z<9.3, forming a representative spectroscopic subset of NIRCam-selected LRDs. We derive a median s…

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 t…

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: 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…

From "The Cliff" to "Virgil": Mapping the Spectral Diversity of Little Red Dots with JWST/NIRSpec

Guillermo Barro, Pablo G. Perez-Gonzalez, Dale Kocevski +26

One of JWST's most unexpected discoveries is the emergence of "Little Red Dots'' (LRDs): compact sources at with blue rest-frame UV continua, red optical slopes, and…
