The Road to Identifying the Earliest Radio-Powerful AGN with the SKA
Jose Afonso, Stergios Amarantidis, Stas Shabala +20
The Epoch of Reionization (EoR) is one of the most pivotal frontiers in modern astrophysics, marking the emergence of the first galaxies, stars, and supermassive black holes (SMBHs…
Exploring biases in derived stellar parameters and the ionizing photon production efficiency
Ravi Jaiswar, Anshu Gupta, Elisabete da Cunha +8
Constraining the timescale and manner in which the Epoch of Reionization (EoR) occurred is a major JWST science goal. However, any constraints on the stellar or ionizing parameters…
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…
A Jet-Induced Shock in a Young, Powerful Radio Galaxy at z=3.00
Nick Seymour, Jess W. Broderick, Gael Noirot +9
The bright radio source, GLEAM J091734-001243 (hereafter GLEAM J0917-0012), was previously selected as a candidate ultra-high redshift (z>5) radio galaxy due to its compact radio s…
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…
