The Quasar Feedback Survey: Ionised Outflows in type 2 QSOs with MUSE data

M. Bianchin, C. M. Harrison, T. Costa +13

We study ionised gas properties in a sample of 18 luminous (log L erg/s) obscured QSOs at 0.085<z<0.2 observed with VLT/MUSE as part of the multi-wavelength Quasa…

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…

Evaluation and insights from a sonification-based planetarium show intended for improving inclusivity

Chris Harrison, Anita Zanella, Aishwarya Girdhar

Audio Universe: Tour of the Solar System is an audio-visual show for planetariums and flatscreen viewing. It is designed in collaboration with members of the blind and vision impai…

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)]…

The Quasar Feedback Survey: characterising CO excitation in quasar host galaxies

S. J. Molyneux, G. Calistro Rivera, C. De Breuck +15

We present a comprehensive study of the molecular gas properties of 17 Type 2 quasars at 0.2 from the Quasar Feedback Survey (L > ), sel…

Complex AGN feedback in the Teacup galaxy. A powerful ionised galactic outflow, jet-ISM interaction, and evidence for AGN-triggered star formation in a giant bubble

G. Venturi, E. Treister, C. Finlez +10

The ~0.1 type-2 QSO J1430+1339 (the 'Teacup') is a complex galaxy showing a loop of ionised gas ~10 kpc in diameter, co-spatial radio bubbles, a compact (~1 kpc) jet, and outflo…

Establishing the impact of luminous AGN with multi-wavelength observations and simulations

C. M. Harrison, A. Girdhar, S. R. Ward

Cosmological simulations fail to reproduce realistic galaxy populations without energy injection from active galactic nuclei (AGN) into the interstellar medium (ISM) and circumgala…

Inspecting spectra with sound: proof-of-concept & extension to datacubes

James W. Trayford, C. M. Harrison, R. C. Hinz +3

We present a novel approach to inspecting galaxy spectra using sound, via their direct audio representation ('spectral audification'). We discuss the potential of this as a complem…

The Quasar Feedback Survey: Revealing the Interplay of Jets, Winds & Emission Line Gas in Type 2 Quasars with Radio Polarization

Silpa Sasikumar, P. Kharb, C. M. Harrison +4

We present results from a combined radio polarization and emission line study of five type 2 quasars at with the Karl G. Jansky Very Large Array (VLA) B-array at 5 GHz and…

Quasar Feedback Survey: Multi-phase outflows, turbulence and evidence for feedback caused by low power radio jets inclined into the galaxy disk

A. Girdhar, C. M. Harrison, V. Mainieri +18

We present a study of a luminous, z=0.15, type-2 quasar (log [L([OIII])/(erg/s)]=42.8) from the Quasar Feedback Survey. It is classified as 'radio-quiet' (log [L(1.4 GHz)/(W/Hz)]=2…

The Quasar Feedback Survey: Discovering hidden Radio-AGN and their connection to the host galaxy ionised gas

M. E. Jarvis, C. M. Harrison, V. Mainieri +18

We present the first results from the Quasar Feedback Survey, a sample of 42 z<0.2, [O III] luminous AGN (L[O III]>10^42.1 ergs/s) with moderate radio luminosities (i.e. L(1.4GHz)>…
