Very Long Baseline Interferometry with the SKA Observatory
J. F. Radcliffe, J. Yang, Z. Paragi +129
Very Long Baseline Interferometry (VLBI) is a fundamental technique that combines signals from telescopes separated by thousands of kilometres to obtain some of the highest-resolut…
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$^{42.…
Connecting outflows with radio emission in active galactic nuclei at cosmic noon
Gabriele S. Ilha, C. M. Harrison, V. Mainieri +17
AGN feedback is a well known mechanism in the evolution of galaxies. One open question is the driving mechanism of galaxy-scale outflows. At low redshift, radio jets often interact…
The Quasar Feedback Survey: zooming into the origin of radio emission with e-MERLIN
Ann Njeri, Chris M. Harrison, Preeti Kharb +7
We present 6 GHz e-MERLIN observations of 42 type 1 and type 2 mostly radio-quiet quasars ( erg s; erg s$^{-…
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…
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)]…
Revisiting a flux recovery systematic error arising from common deconvolution methods used in aperture-synthesis imaging
Jack F. Radcliffe, R. J. Beswick, A. P. Thomson +2
The point-spread function (PSF) is a fundamental property of any astronomical instrument. In interferometers, differing array configurations combined with their coverage, and…
SPARCS-North Wide-field VLBI Survey: Exploring the resolved MicroJy extra-galactic radio source population with EVN+e-MERLIN
Ann Njeri, Robert J. Beswick, Jack F. Radcliffe +8
The SKA PAthfinder Radio Continuum Surveys (SPARCS) are providing deep-field imaging of the faint (sub-mJy) extra-galactic radio source populations through a series of reference su…
The e-MERLIN Galaxy Evolution Survey (e-MERGE): Overview and Survey Description
T. W. B. Muxlow, A. P. Thomson, J. F. Radcliffe +37
We present an overview and description of the eMERLIN Galaxy Evolution survey (eMERGE) Data Release 1 (DR1), a large program of high-resolution 1.5 GHz radio observations of the GO…
High-resolution radio astronomy: an outlook for Africa
Leonid I. Gurvits, Robert Beswick, Melvin Hoare +5
Very Long Baseline Interferometry (VLBI) offers unrivalled resolution in studies of celestial radio sources. The subjects of interest of the IAU Symposium No. 356, the Active Galac…
