A large overdensity of LRD-like galaxies discovered by JWST in the SPT2349-56 protocluster at z=4.30
Scott C. Chapman, Kedar A. Phadke, Nikolaus Sulzenauer +20
We present 11 newly identified ultra-red galaxies selected with JWST/NIRCam in the core of the z=4.3 protocluster SPT2349-56. Although these sources are not yet spectroscopically c…
An extreme ram-pressure stripping event in a protocluster at redshift 4.3
Dazhi Zhou, Scott C. Chapman, Manuel Aravena +16
In the nearby Universe, the environment plays a crucial role in suppressing star formation in dense regions. In particular, ram-pressure stripping (RPS) is a major mechanism for re…
An Overabundance of Radio-AGN in the SPT2349-56 Protocluster: Preheating the Intra-Cluster Medium
Scott C. Chapman, Roger P. Deane, Dazhi Zhou +22
Following the detection of a radio-loud Active Galactic Nucleus (AGN) in the z=4.3 protocluster SPT2349-56, we have obtained additional observations with MeerKAT in S-band (2.4 GHz…
A large thermal energy reservoir in the nascent intracluster medium at a redshift of 4.3
Dazhi Zhou, Scott Chapman, Manuel Aravena +21
Most baryons in present-day galaxy clusters exist as hot gas (), forming the intracluster medium (ICM). Cosmological simulations predict th…
A Large Molecular Gas Reservoir in the Protocluster SPT234956 at
Dazhi Zhou, Scott C. Chapman, Nikolaus Sulzenauer +13
We present Atacama Compact Array (ACA) Band-3 observations of the protocluster SPT234956, an extreme system hosting submillimeter galaxies (SMGs) at $z\,{=}\,4.3…
Evidence for environmental effects in the protocluster core SPT234956
Chayce Hughes, Ryley Hill, Scott Chapman +16
We present ALMA observations of the [CI] 492 and 806GHz fine-structure lines in 25 dusty star-forming galaxies (DSFGs) at in the core of the SPT234956 protoclu…
A 100 Mpc structure traced by hyperluminous galaxies around a massive = 2.85 protocluster
George C. P. Wang, Scott C. Chapman, Nikolaus Sulzenauer +9
We present wide-field mapping at 850 m and 450 m of the = 2.85 protocluster in the HS154919 field using the Submillimetre Common User Bolometer Array 2 (SCUBA-2). Spec…
Brightest Cluster Galaxy Formation in the z=4.3 Protocluster SPT2349-56: Discovery of a Radio-Loud AGN
Scott C. Chapman, Ryley Hill, Manuel Aravena +29
We have observed the z=4.3 protocluster SPT2349-56 with ATCA with the aim of detecting radio-loud active galactic nuclei (AGN) amongst the ~30 submillimeter galaxies identified in…
Rapid build-up of the stellar content in the protocluster core SPT234956 at
Ryley Hill, Scott Chapman, Kedar A. Phadke +22
The protocluster SPT234956 at contains one of the most actively star-forming cores known, yet constraints on the total stellar mass of this system are highly uncer…
