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…
A striking excess of red quasars with steep radio spectral slopes: a dusty blow-out phase revealed through AGN-driven shocks?
Ciera L. Sargent, David M. Alexander, Claire L. Greenwell +5
Red quasars exhibit a higher incidence of compact (galaxy-scale or smaller) radio emission than blue quasars, arising from systems near the radio-loud/radio-quiet threshold. In thi…
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…
KASHz+SUPER: Evidence of cold molecular gas depletion in AGN hosts at cosmic noon
E. Bertola, C. Circosta, M. Ginolfi +32
The energy released by AGN has the potential to heat or remove the gas of the ISM, thus likely impacting the cold molecular gas reservoir of host galaxies at first, with star forma…
SUPER VIII. Fast and Furious at : obscured type-2 active nuclei host faster ionised winds than type-1 systems
G. Tozzi, G. Cresci, M. Perna +22
We present spatially resolved VLT/SINFONI spectroscopy with adaptive optics of type-2 active galactic nuclei (AGN) from the SINFONI Survey for Unveiling the Physics and Effect of R…
Feedback and ionized gas outflows in four low-radio power AGN at z 0.15
L. Ulivi, G. Venturi, G. Cresci +19
An increasing number of observations and simulations suggests that low-power (<10 erg s) jets may be a significant channel of feedback produced by active galactic nuc…
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…
The multiwavelength properties of red QSOs -- Evidence for dusty winds as the origin of QSO reddening
G. Calistro-Rivera, D. M. Alexander, D. J. Rosario +11
Fundamental differences in the radio properties of red quasars (QSOs), as compared to blue QSOs, have been recently discovered, positioning them as a potential key population in th…
Establishing the impact of powerful AGN on their host galaxies
C. M. Harrison, S. J. Molyneux, J. Scholtz +1
Establishing the role of active galactic nuclei (AGN) during the formation of galaxies remains one of the greatest challenges of galaxy formation theory. Towards addressing this, w…
The impact of AGN on their host galaxies
C. M. Harrison
In these proceedings I briefly: (1) review the impact (or "feedback") that active galactic nuclei (AGN) are predicted to have on their host galaxies and larger scale environment, (…
