Not all protoclusters host evolved galaxies: Evidence for reduced environmental effects in a lower halo mass protocluster at

Callum Witten, Pascal A. Oesch, Jake S. Bennett +5

The progenitors of present-day galaxy clusters offer crucial insight into how galaxies and large-scale structure co-evolve in the early Universe. We present JWST/NIRCam grism spect…

Early massive galaxy formation in the core of a galaxy protocluster 650 million years after the Big Bang

Yoshinobu Fudamoto, Yurina Nakazato, Daniel Ceverino +24

Rest-frame optical observations with the James Webb Space Telescope (JWST) have uncovered a population of massive galaxies, exceeding solar masses, present less than a bi…

JWST COSMOS-3D: Spectroscopic Census and Luminosity Function of [O III] Emitters at 6.75<z<9.05 in COSMOS

Romain A. Meyer, Feige Wang, Koki Kakiichi +38

We present a catalogue of spectroscopically selected [OIII]+Hb emitters at 6.75<z<9.05 and the resulting [OIII] 5008 ÅLuminosity Function (LF) in the COSMOS field. We leverage the…

Exploring Spatially-Resolved Metallicities, Dynamics and Outflows in Low-Mass Galaxies at

L. R. Ivey, J. Scholtz, A. L. Danhaive +18

A majority of JWST/NIRSpec/IFU studies at high redshifts to date have focused on UV-bright or massive objects, while our understanding of low-mass galaxies at early cosmic times re…

Stochastic star formation activity of galaxies within the first billion years probed by JWST

C. Carvajal-Bohorquez, L. Ciesla, N. Laporte +8

In this work, we aim at characterizing the burstiness level of high-redshift galaxy SFHs and its evolution. We implement a stochastic SFH in CIGALE using PSD, to estimate the burst…

Before its time: a remarkably evolved protocluster core at z=7.88

Callum Witten, Pascal A. Oesch, William McClymont +11

Protoclusters represent the most extreme environments in the very early Universe. They form from large-scale dark matter overdensities, harbouring an overabundance of galaxies fed…
