REBELS-MOSFIRE: Weak CIII] Emission is Typical Among Extremely UV-bright, Massive Galaxies at

Ryan Endsley, Alice E. Shapley, Michael W. Topping +16

We present Keck/MOSFIRE H-band spectroscopic measurements covering the [CIII]1907, CIII]1909 doublet for a sample of 8 z~7 spectroscopically-confirmed star-forming galaxies drawn f…

Hiding behind a curtain of dust: Gas and dust properties of an ultra-luminous strongly-lensed z = 3.75 galaxy behind the Milky Way disk

Belén Alcalde Pampliega, Kevin C. Harrington, Aristeidis Amvrosiadis +21

We present a detailed analysis of J154506, a strongly lensed submillimeter galaxy behind the Lupus-I molecular cloud, and characterisation of its physical properties using a combin…

REBELS-IFU: Dust Build-up in Massive Galaxies at Redshift 7

Hiddo Algera, Lucie Rowland, Mauro Stefanon +22

In recent years, observations with the JWST have started to map out the rapid metal enrichment of the early Universe, while (sub)millimeter observations have simultaneously begun t…

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…

Discovery of a Ultra Steep Spectrum Radio Halo in the MeerKAT-South Pole Telescope Survey

Isaac S. Magolego, Roger P. Deane, Kshitij Thorat +15

Radio halos are diffuse synchrotron sources that trace the turbulent intracluster medium (ICM) of galaxy clusters. However, their origin remains unknown. Two main formation models…

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…
