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$^{42.…
Connecting outflows with radio emission in active galactic nuclei at cosmic noon
Gabriele S. Ilha, C. M. Harrison, V. Mainieri +17
AGN feedback is a well known mechanism in the evolution of galaxies. One open question is the driving mechanism of galaxy-scale outflows. At low redshift, radio jets often interact…
The Quasar Feedback Survey: zooming into the origin of radio emission with e-MERLIN
Ann Njeri, Chris M. Harrison, Preeti Kharb +7
We present 6 GHz e-MERLIN observations of 42 type 1 and type 2 mostly radio-quiet quasars ( erg s; erg s$^{-…
The VLBA CANDELS GOODS-North Survey. II -- Wide-field source catalogue comparison between the VLBA, EVN, e-MERLIN and VLA
Ann Njeri, Roger. P. Deane, J. F. Radcliffe +5
Deep radio surveys of extragalactic legacy fields trace a large range of spatial and brightness temperature sensitivity scales, and therefore have differing biases to radio-emittin…
The VLBA CANDELS GOODS-North Survey. I -- Survey Design, Processing, Data Products, and Source Counts
Roger P. Deane, Jack F. Radcliffe, Ann Njeri +9
The past decade has seen significant advances in wide-field cm-wave very long baseline interferometry (VLBI), which is timely given the wide-area, synoptic survey-driven strategy o…
Quasar Feedback Survey: molecular gas affected by central outflows and by ~10 kpc radio lobes reveal dual feedback effects in `radio quiet' quasars
A. Girdhar, C. M. Harrison, V. Mainieri +17
We present a study of molecular gas, traced via CO (3-2) from ALMA data, of four z< 0.2, `radio quiet', type 2 quasars (log [L(bol)/(erg/s)] = 45.3 - 46.2; log [L(1.4 GHz)/(W/Hz)]…
