Spider-Webb: JWST Near Infrared Camera resolved galaxy star formation and nuclear activities in the Spiderweb protocluster at z=2.16

Rhythm Shimakawa, Yusei Koyama, Tadayuki Kodama +8

Near-infrared (NIR) emission is less affected by dust than UV and optical emission and is therefore useful for studying the properties of dust-obscured galaxies. Although rest-fram…

The RAdio Galaxy Environment Reference Survey (RAGERS): Evidence of an anisotropic distribution of submillimeter galaxies in the 4C 23.56 protocluster at z=2.48

Dazhi Zhou, Thomas R. Greve, Bitten Gullberg +41

High-redshift radio(-loud) galaxies (HRGs) are massive galaxies with powerful radio-loud active galactic nuclei (AGNs) and serve as beacons for protocluster identification. Howe…

Star formation activity of low-mass galaxies at the peak epoch of galaxy formation probed by deep narrow-band imaging

Kazuki Daikuhara, Tadayuki Kodama, Jose M. Pérez-Martínez +5

Low-mass galaxies at high redshifts are the building blocks of more massive galaxies at later times and are thus key populations for understanding galaxy formation and evolution. W…

JWST's first glimpse of a z > 2 forming cluster reveals a top-heavy stellar mass function

Hanwen Sun, Tao Wang, Ke Xu +11

Clusters and their progenitors (protoclusters) at z = 2-4, the peak epoch of star formation, are ideal laboratories to study the formation process of both the clusters themselves a…

Enhanced star formation and metallicity deficit in the USS 1558-003 forming protocluster at z=2.53

Jose Manuel Pérez-Martínez, Tadayuki Kodama, Yusei Koyama +6

We use K-band multi-object near-infrared spectroscopy with Keck/MOSFIRE to search for environmental imprints on the gas properties of 27 narrow-band selected H emitters (HAEs) a…

New insights into the role of AGNs in forming the cluster red sequence

Rhythm Shimakawa, José Manuel Pérez-Martínez, Yusei Koyama +7

As a considerable investment of time from various telescope facilities were dedicated toward studying the Spiderweb protocluster at , it so far remains one of the most exten…
