Too many protoclusters? Reconciling the overabundance of cluster progenitors within the first billion years of the Universe

Callum Witten, Jake S. Bennett, Pascal A. Oesch +8

JWST has revealed an overabundance of apparent (`Coma'-like) cluster progenitors at that is two (300) times in excess of, and in () tension with, the numb…

From Grism to IFU: Revising the Redshift and Nature of the Massive Dusty Galaxy S1 with JWST and ALMA

Mengyuan Xiao, Longji Bing, Gabriel Brammer +21

We report a revised spectroscopic redshift for the dusty massive galaxy S1, previously inferred with an exceptionally high baryon-to-star conversion efficiency from NIRCam slitless…

The ALMA REBELS survey: [OIII] line scans of UV-bright galaxies

I. F. van Leeuwen, R. J. Bouwens, J. A. Hodge +17

We present the [OIII] spectral scan results from the ALMA Large Program REBELS (Reionization Era Bright Emission Line Survey). The generally high luminosity of [OI…

Constraints on the early Universe star formation efficiency from galaxy clustering and halo modeling of H and [O III] emitters

Marko Shuntov, Pascal A. Oesch, Sune Toft +13

We develop a theoretical framework to provide observational constraints on the early Universe galaxy-halo connection by combining measurements of the UV luminosity function (UVLF)…

Detection of [OIII]88m in JADES-GS-z14-0 at z=14.1793

Sander Schouws, Rychard J. Bouwens, Katherine Ormerod +13

We report the first successful ALMA follow-up observations of a secure JWST-selected galaxy, by robustly detecting () the [OIII] line in JADES-GS-z14-0…

Deep Constraints on [CII]158m in JADES-GS-z14-0: Further Evidence for a Galaxy with Low Gas Content at z=14.2

Sander Schouws, Rychard J. Bouwens, Hiddo Algera +14

We present deep ALMA observations targeting the [CII] line in JADES-GS-z14-0, the most distant known galaxy at z=14.1793. We do not detect the [CII] line…
