Non-thermal emission in jets and winds: Expected emission and spectral index distributions
M. Meenakshi, D. Mukherjee, G. Bodo +5
The origin of synchrotron emission in compact radio sources associated with active galactic nuclei (AGN) remains poorly understood. In a series of papers, we have examined diagnost…
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 García-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 ($T \gtrsim 10^{6…
A case study of translating sonifications across musical cultures for an educational application
Chris M. Harrison, James W. Trayford, Arron George +4
Sonification can be part of educational resources that can be accessible to those who prefer, or require, non-visual learning methods. Furthermore, sonification can contribute to a…
STRAUSS: Sonification Tools & Resources for Analysis Using Sound Synthesis
James W. Trayford, Samantha Youles, Chris Harrison +2
Sonification, or conveying data using non-verbal audio, is a relatively niche but growing approach for presenting data across multiple specialist domains including astronomy, clima…
The Quasar Feedback Survey: zooming into the origin of radio emission with e-MERLIN
Ann Njeri, Chris M. Harrison, Preeti Kharb +7
We present 6 GHz e-MERLIN observations of 42 type 1 and type 2 mostly radio-quiet quasars ( erg s; erg s$^{-…
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…
AGN-driven outflows in clumpy media: multiphase structure and scaling relations
Samuel Ruthven Ward, Tiago Costa, Chris M. Harrison +1
Small-scale winds driven from accretion discs surrounding active galactic nuclei (AGN) are expected to launch kpc-scale outflows into their host galaxies. However, the ways in whic…
A comparative study of radio signatures from winds and jets: Modelling synchrotron emission and polarization
Moun Meenakshi, Dipanjan Mukherjee, Gianluigi Bodo +2
Outflows driven by active galactic nuclei (AGN) are seen in numerous compact sources; however, it has remained unclear how to distinguish between the driving mechanisms, such as wi…
Observational Tests of Active Galactic Nuclei Feedback: An Overview of Approaches and Interpretation
Chris M. Harrison, Cristina Ramos Almeida
Growing supermassive black holes (Active Galactic Nuclei; AGN) release energy with the potential to alter their host galaxies and larger-scale environment; a process named "AGN fee…
Dust beyond the torus: Revealing the mid-infrared heart of local Seyfert ESO 428-G14 with JWST/MIRI
Houda Haidar, David J. Rosario, Almudena Alonso-Herrero +34
Polar dust has been discovered in a number of local Active Galactic Nuclei (AGN), with radiation-driven torus models predicting a wind to be its main driver. However, little is kno…
