The Quasar Feedback Survey: Revealing the importance of sensitive radio imaging for AGN identification deeper into the radio-quiet regime
Ann Njeri, Chris M. Harrison, Preeti Kharb +8
We present new sub-arcsecond (0.3-1 arcsec; 1--3\,kpc) VLA imaging at 1.4\,GHz and 6\,GHz of 29 optically-selected, [O~{\sc iii}] luminous ( > 10$^{42.…
Bringing together African & European research communities with an inclusive astronomy conference
Chris M. Harrison, Leah Morabito, Ann Njeri
We report on an international scientific conference, where we brought together African and European academic astronomers. This aimed to bridge the gap between those in position of…
Connecting outflows with radio emission in active galactic nuclei at cosmic noon
Gabriele S. Ilha, C. M. Harrison, V. Mainieri +17
AGN feedback is a well known mechanism in the evolution of galaxies. One open question is the driving mechanism of galaxy-scale outflows. At low redshift, radio jets often interact…
The Quasar Feedback Survey: zooming into the origin of radio emission with e-MERLIN
Ann Njeri, Chris M. Harrison, Preeti Kharb +7
We present 6 GHz e-MERLIN observations of 42 type 1 and type 2 mostly radio-quiet quasars ( erg s; erg s$^{-…
