A Search for Radio-loud Quasars within the Epoch of Reionization
(Astronomical Society of the Pacific, 2004)
The Universe became fully reionized, and observable optically, at a time corresponding to redshift z~6.5, so it is only by studying the HI and molecular absorption lines against higher-redshift, radio-loud sources that one ...
The 6** sample and the highest redshift radio galaxies
(World Scientific Publishing, 2004)
We present a new radio sample, 6C** designed to find radio galaxies at z > 4 and discuss some of its near-infrared imaging follow-up results.
The accretion history of the Universe with the Square Kilometre Array
(2004)
In this paper we investigate how the Square Kilometre Array (SKA) can aid in determining the evolutionary history of active galactic nuclei (AGN) from redshifts z = 0 ! 6. Given the vast collecting area of the SKA, it will ...
Using MgII to investigate quasars and their black-hole masses
(Astronomical Society of the Pacific, 2004)
We highlight the importance of the Mg II λ2800 emission-line doublet in probing high-redshift quasars and their supermassive black holes. In the SDSS era, where large scale investigations of quasars across the age of the ...
A large area search for radion-loud quasars within the epoch of reionization
(World Scientific Publishing, 2004)
The Universe became fully reionized, and observable optically, at a time corresponding to redshift z ~ 6.5, so it is only by studying the HI and molecular absorption lines against higher-redshift, radio-loud sources that ...
