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…

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…

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…

JWST MIRI/MRS observations of hot molecular gas in an AGN host galaxy at Cosmic Noon

D. Kakkad, V. Mainieri, Takumi S. Tanaka +27

Active Galactic Nuclei (AGN) are believed to play a central role in quenching star formation by removing or destroying molecular gas from host galaxies via radiation-pressure drive…

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…

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…

At the end of cosmic noon: Short gas depletion times in unobscured quasars at 1

M. Frias Castillo, M. Rybak, J. Hodge +8

Unobscured quasars (QSOs) are predicted to be the final stage in the evolutionary sequence from gas-rich mergers to gas-depleted, quenched galaxies. Studies of this population, how…

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…

Cosmological simulations predict that AGN preferentially live in gas-rich, star-forming galaxies despite effective feedback

Samuel Ruthven Ward, Chris Harrison, Tiago Costa +1

Negative feedback from active galactic nuclei (AGN) is the leading mechanism for the quenching of massive galaxies in the vast majority of modern galaxy evolution models. However,…
