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…

Millimeter-wave observations of Euclid Deep Field South using the South Pole Telescope: A data release of temperature maps and catalogs

M. Archipley, A. Hryciuk, L. E. Bleem +108

Context. The South Pole Telescope third-generation camera (SPT-3G) has observed over 10,000 square degrees of sky at 95, 150, and 220 GHz (3.3, 2.0, 1.4 mm, respectively) and will…

A census of star-formation and gas mass tracers in two lensed dusty star-forming galaxies

David Vizgan, Joaquin D. Vieira, Justin S. Spilker +20

We present new and archival Atacama Large Millimeter/submillimeter Array (ALMA) observations of two strongly lensed dusty star-forming galaxies (DSFGs) selected from the South Pole…

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…

Bright [CII]158m Streamers as a Beacon for Giant Galaxy Formation in SPT234956 at

Nikolaus Sulzenauer, Axel Weiß, Ryley Hill +17

Observations of extreme starbursts, often located in the cores of protoclusters, challenge the classical bottom-up galaxy formation paradigm. Giant elliptical galaxies at mus…

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…
