An askap survey for hi absorption towards dust-obscured quasars
(Oxford Academic, 2019)Obscuration of quasars by accreted gas and dust, or dusty intervening galaxies, can cause active galactic nuclei (AGN) to be missed in optically selected surveys. Radio observations can overcome this dust bias. In particular, ... -
Galaxy and Mass Assembly (GAMA): A WISE Study of the Activity of Emission-line Systems in G23
(2020)We present a detailed study of emission-line systems in the GAMA G23 region, making use of WISE photometry that includes carefully measured resolved sources. After applying several cuts to the initial catalogue of ∼41,000 ... -
A new sample of southern radio galaxies: Host-galaxy masses and star-formation rates
(Oxford University Press, 2019)In this study we define a new sample of distant powerful radio galaxies in order to study their host galaxy properties and provide targets for future observations of H I absorption with new radio telescopes and to understand ...
