Tracing AGN Feedback Power with Cool/Warm Outflow Densities: Predictions and Observational Implications
Ivan Almeida, Tiago Costa, Chris M. Harrison +1
Winds launched at the scale of the accretion disc or dusty torus in Active Galactic Nuclei (AGN) are thought to drive energy-conserving outflows that shape galaxy evolution. The ke…
GATOS XI : Excess dust heating in the Narrow Line Regions of nearby AGN revealed with JWST/MIRI
Houda Haidar, David J. Rosario, Ismael GarcÃa-Bernete +38
We present JWST/MIRI imaging of eight nearby Active Galactic Nuclei (AGN) from the GATOS survey to investigate the physical conditions of extended dust in their narrow line regions…
Mixing between AGN winds and ISM clouds produces luminous X-ray emission
Samuel Ruthven Ward, Tiago Costa, Chris M. Harrison +1
Active galactic nuclei (AGN) drive powerful, multiphase outflows that are thought to play a key role in galaxy evolution. The hot, shocked phase of these outflows ($T \gtrsim 10^{6…
The Quasar Feedback Survey: zooming into the origin of radio emission with e-MERLIN
Ann Njeri, Chris M. Harrison, Preeti Kharb +7
We present 6 GHz e-MERLIN observations of 42 type 1 and type 2 mostly radio-quiet quasars ( erg s; erg s$^{-…
Unveiling AGN Outflows: [O iii] Outflow Detection Rates and Correlation with Low-Frequency Radio Emission
Emmy L. Escott, Leah K. Morabito, Jan Scholtz +10
Some Active Galactic Nuclei (AGN) host outflows which have the potential to alter the host galaxy's evolution (AGN feedback). These outflows have been linked to enhanced radio emis…
Investigating Differences in the Palomar-Green Blazar Population Using Polarization
Janhavi Baghel, P. Kharb, T. Hovatta +5
We present polarization images with the Karl G. Jansky Very Large Array (VLA) in A and B-array configurations at 6 GHz of 7 radio-loud (RL) quasars and 8 BL Lac objects belonging t…
