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…
The Massive and Distant Clusters of WISE Survey 2: Detection of splashback radii in galaxy cluster total light stacks
A. Trudeau, Anthony H. Gonzalez, K. Thongkham +6
The splashback radius, the radius of the apocenter of the first orbit of infalling material, is a measurable quantity marking the boundary between a galaxy cluster and its infallin…
The Massive and Distant Clusters of WISE Survey 2: Splashback Radii to z=1.65 from Galaxy Density Profiles
Khunanon Thongkham, Anthony H. Gonzalez, Mark Brodwin +6
The Massive and Distant Clusters of WISE Survey 2 (MaDCoWS2) is a WISE-selected catalog of galaxy clusters at covering an effective area of deg. In this paper…
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 WeiÃ, 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…
