A Compact Proto-group at : A Massive Galaxy Caught in Formation

Ronaldo Laishram, Yusei Koyama, Fengwu Sun +11

The authors report the discovery of a compact galaxy proto‑group at redshift ~5, confirming six members spectroscopically and measuring their stellar masses, star‑formation propert…

Kinematic Mapping of Giant Arcs: A New Method to Locate Lensing Critical Curves

Ruwen Zhou, Liang Dai, Lingyuan Ji +4

The vicinity of lensing critical curves features highly magnified portions of lensed galaxies. Accurate knowledge of the location and shape of the critical curve will be useful for…

A stellar dynamical mass measurement of an inactive black hole at redshift 2

Andrew B. Newman, Meng Gu, Sirio Belli +34

Supermassive black holes and their host galaxies grow together over time, producing correlations between the black hole mass and various galaxy properties. Determining the evolutio…

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…

Everything Every Band All at Once I: A Global Morphology Catalog in Abell 2744 based on UNCOVER/MegaScience

Yunchong Zhang, Tim B. Miller, Sedona H. Price +31

We present spectrally-resolved structural parameter measurements of 28,274 sources from the legacy lensing field of Abell 2744, quantifying global structures from observed $0.7 μm…
