Connection between steep radio spectral slopes and dust extinction in QSOs: evidence for outflow-driven shocks in dusty QSO
V. A. Fawcett, C. M. Harrison, D. M. Alexander +9
Recent studies have found a striking positive correlation between the amount of dust obscuration and enhanced radio emission in quasi-stellar objects (QSOs). However, what causes t…
The VST ATLAS Quasar Survey III: Halo mass function via quasar clustering and quasar-CMB lensing cross-clustering
Alice M. Eltvedt, T. Shanks, N. Metcalfe +4
We exploit the VST ATLAS quasar/QSO catalogue to perform three measurements of the quasar halo mass profile. First, we make a new estimate of the angular auto-correlation function…
How does the radio enhancement of broad absorption line quasars relate to colour and accretion rate?
J. W. Petley, L. K. Morabito, A. L. Rankine +8
The origin of radio emission in different populations of radio-quiet quasars is relatively unknown, but recent work has uncovered various drivers of increased radio-detection fract…
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…
Broad Absorption Line Quasars in the Dark Energy Spectroscopic Instrument Early Data Release
S. Filbert, P. Martini, K. Seebaluck +41
Broad absorption line (BAL) quasars are characterized by gas clouds that absorb flux at the wavelength of common quasar spectral features, although blueshifted by velocities that c…
KASHz: No evidence for ionised outflows instantaneously suppressing star formation in moderate luminosity AGN at -
J. Scholtz, C. M. Harrison, D. J. Rosario +9
As part of our KMOS AGN Survey at High-redshift (KASHz), we present spatially-resolved VLT/KMOS and VLT/SINFONI spectroscopic data and ALMA 870m continuum imaging of eight =1…
The KMOS AGN Survey at High redshift (KASHz): the prevalence and drivers of ionised outflows in the host galaxies of X-ray AGN
C. M. Harrison, D. M. Alexander, J. R. Mullaney +7
We present the first results from the KMOS AGN Survey at High redshift (KASHz), a VLT/KMOS integral-field spectroscopic survey of z>0.6 AGN. We present galaxy-integrated spectra of…
Kiloparsec-scale outflows are prevalent among luminous AGN: outflows and feedback in the context of the overall AGN population
C. M. Harrison, D. M. Alexander, J. R. Mullaney +1
We present integral field unit (IFU) observations covering the [O III]4959,5007 and H-Beta emission lines of sixteen z<0.2 type 2 active galactic nuclei (AGN). Our targets are sele…
