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…

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…

An Image-Plane Approach to Gravitational Lens Modeling of Interferometric Data

Nan Zhang, Sreevani Jarugula, Justin S. Spilker +11

Strong gravitational lensing acts as a cosmic telescope, enabling the study of the high-redshift universe. Astronomical interferometers, such as the Atacama Large Millimeter/submil…

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 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…
