Vz-GAL Dusty Star-Forming Galaxies: Revisiting the CO-H2 Conversion Factor Tension
Prachi Prajapati, Axel Weiss, Dominik Riechers +17
The CO luminosity-to-H mass conversion factor () remains a debated uncertainty in determining molecular gas masses of high-redshift dusty star-forming galaxies (DSFGs).…

We present [O] 88m observations towards four -selected dusty star-forming galaxies (DSFGs; log L/L = 13.5 - 14 at $z…
Vz-GAL: Probing Cold Molecular Gas in Dusty Star-forming Galaxies at z=1-6
Prachi Prajapati, Dominik Riechers, Pierre Cox +20
We present the first results of Vz-GAL, a high-redshift CO(J=1-0) large survey with the Karl G. Jansky Very Large Array, targeting 92 Herschel-selected, infrared-luminous, dusty st…
Gas-Poor Hosts and Gas-Rich Companions of 3.5 Radio Active Galactic Nuclei: ALMA Insights into Jet Triggering and Feedback
Wuji Wang, Carlos De Breuck, Dominika Wylezalek +7
Cold gaseous systems play important roles in galaxy evolution by possibly providing fuel to ignite active galactic nuclei (AGN) activity and star-formation. In this work, we analyz…
The Centre of Attention: a Powerful Radio Galaxy Pinpoints a NIR-Dark Protocluster at z~3.9
A. J. Hedge, N. Seymour, J. W. Broderick +8
We report the discovery of a protocluster identified from Atacama Large Millimetre/sub-millimetre Array Band 3 spectral scans of a bright radio source selected from the…
JWST + ALMA ubiquitously discover companion systems within kpc around four 3.5 luminous radio-loud AGN
Wuji Wang, Carlos De Breuck, Dominika Wylezalek +11
Mergers play important roles in galaxy evolution at and beyond Cosmic Noon (). They are found to be a trigger of active galactic nuclei (AGN) activity and a process for gro…
The SUPERCOLD-CGM survey: II. [\ion{C}{1}] emission and the physical conditions of cold gas in Enormous Ly nebulae at
Jianan Li, Bjorn H. C. Emonts, Zheng Cai +13
We report ALMA and ACA observations of atomic carbon ([\ion{C}{1}]) and dust continuum in 10 Enormous Ly Nebulae hosting ultra-luminous Type-I QSOs at , as par…
Gas dynamics in an AGN-host galaxy at : regular rotation, non-circular motions, and mass models
Lingrui Lin, Federico Lelli, Carlos De Breuck +9
The gas dynamics of galaxies provide critical insights into the evolution of both baryons and dark matter (DM) across cosmic time. In this context, galaxies at cosmic noon -- the p…
The GLEAMing of the first supermassive black holes: III. Radio sources with ultra-faint host galaxies
J. W. Broderick, N. Seymour, G. Drouart +10
We present deep near-infrared -band imaging for 35 of the 53 sources from the high-redshift () radio galaxy candidate sample defined in Broderick et al. (2022). T…
JWST discovers an AGN ionization cone but only weak radiative-driven feedback in a powerful 3.5 radio-loud AGN
Wuji Wang, Dominika Wylezalek, Carlos De Breuck +7
We present the first results from a JWST program studying the role played by powerful radio jets in the evolution of the most massive galaxies at the onset of Cosmic Noon. Using NI…
Absorption of Millimeter-band CO and CN in the Early Universe: Molecular Clouds in Radio Galaxy B2 0902+34 at Redshift 3.4
Bjorn Emonts, Steve Curran, George Miley +9
Using the Karl G. Jansky Very Large Array (VLA), we have detected absorption lines due to carbon-monoxide, CO(J=0-1), and the cyano radical, CN(N=0-1), associated with radio galaxy…
COALAS II. Extended molecular gas reservoirs are common in a distant, forming galaxy cluster
Zhengyi Chen, Helmut Dannerbauer, Matthew Lehnert +24
This paper presents the results of 475 hours of interferometric observations with the Australia Telescope Compact Array towards the Spiderweb protocluster at \(z=2.16\). We search…
3D tomography of the giant Ly nebulae of 3--5 radio-loud AGN
Wuji Wang, Dominika Wylezalek, Joël Vernet +12
Ly emission nebulae are ubiquitous around high-z galaxies and are tracers of the gaseous environment on scales out to >100 kpc. High-z radio galaxies (HzRGs, type-2 radio-loud q…
