Radio-dust connection in quasars driven by powerful ionised outflows
V. A. Fawcett, C. M. Harrison, T. Costa +8
Feedback from dusty quasars is thought to be a key driver in galaxy evolution. Multiple studies have reported a link between dust extinction and radio emission in quasars, possibly…
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…
Connection between steep radio spectral slopes and dust extinction in QSOs: evidence for outflow-driven shocks in dusty QSO
V. A. Fawcett, C. M. Harrison, D. M. Alexander +9
Recent studies have found a striking positive correlation between the amount of dust obscuration and enhanced radio emission in quasi-stellar objects (QSOs). However, what causes t…
Ubiquitous radio emission in quasars: predominant AGN origin and a connection to jets, dust and winds
G. Calistro-Rivera, D. M. Alexander, C. M. Harrison +16
We present a comprehensive study of the physical origin of radio emission in optical quasars at redshifts z < 2.5. We focus particularly on the associations between compact radio e…
Deconvolution of JWST/MIRI Images: Applications to an AGN Model and GATOS Observations of NGC 5728
M. T. Leist, C. Packham, D. J. V. Rosario +32
The superb image quality, stability and sensitivity of the JWST permit deconvolution techniques to be pursued with a fidelity unavailable to ground-based observations. We present a…
A striking relationship between dust extinction and radio detection in DESI QSOs: evidence for a dusty blow-out phase in red QSOs
V. A. Fawcett, D. M. Alexander, A. Brodzeller +39
We present the first eight months of data from our secondary target program within the ongoing Dark Energy Spectroscopic Instrument (DESI) survey. Our program uses a mid-infrared a…
