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…
Outflows in the Radio-Intermediate Quasar III Zw 2: A Polarization Study with the EVLA & uGMRT
Silpa S., P. Kharb, C. M. Harrison +4
We present results from a polarization study of the radio-intermediate quasar, III Zw 2, at a redshift of 0.089, with the upgraded Giant Metrewave Radio Telescope (uGMRT) at 685 MH…
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)>…
The VANDELS ESO public spectroscopic survey: final Data Release of 2087 spectra and spectroscopic measurements
B. Garilli, R. McLure, L. Pentericci +94
VANDELS is an ESO Public Spectroscopic Survey designed to build a sample of high signal to noise, medium resolution spectra of galaxies at redshift between 1 and 6.5. Here we prese…
The Radio Structure of the Narrow-Line Seyfert 1 Mrk 783 with VLBA and e-MERLIN
E. Congiu, P. Kharb, A. Tarchi +9
In this paper, we present the analysis of new radio and optical observations of the narrow-line Seyfert 1 galaxy Mrk 783. 1.6 GHz observations performed with the e-MERLIN interfero…
The XXL survey: XLII. Detection and characterization of the galaxy population of distant galaxy clusters in the XXL-N/VIDEO field: A tale of variety
A. Trudeau, C. Garrel, J. Willis +16
Context. Distant galaxy clusters provide an effective laboratory in which to study galaxy evolution in dense environments and at early cosmic times. Aims. We aim to identify distan…
Probing the origin of low-frequency radio emission in PG quasars with the uGMRT -- I
Silpa S., P. Kharb, L. C. Ho +3
We present the results from 685 MHz observations with the upgraded Giant Metrewave Radio Telescope (uGMRT) of 22 quasars belonging to the Palomar-Green (PG) quasar sample. Only fou…
High molecular gas content and star formation rates in local galaxies that host quasars, outflows and jets
M. E. Jarvis, C. M. Harrison, V. Mainieri +11
We use a sample of powerful z~0.1 type 2 quasars ('obscured'; log[L(AGN)/erg/s]>~45), which host kiloparsec-scale ionized outflows and jets, to identify possible signatures of AGN…
Establishing the impact of powerful AGN on their host galaxies
C. M. Harrison, S. J. Molyneux, J. Scholtz +1
Establishing the role of active galactic nuclei (AGN) during the formation of galaxies remains one of the greatest challenges of galaxy formation theory. Towards addressing this, w…
Extreme ionised outflows are more common when the radio emission is compact in AGN host galaxies
S. J. Molyneux, C. M. Harrison, M. E. Jarvis
Using a sample of 2922 z<0.2, spectroscopically-identified Active Galactic Nuclei (AGN) we explore the relationship between radio size and the prevalence of extreme ionised outflow…
Prevalence of radio jets associated with galactic outflows and feedback from quasars
M. E. Jarvis, C. M. Harrison, A. P. Thomson +7
We present 1-7 GHz high-resolution radio imaging (VLA and e-MERLIN) and spatially-resolved ionized gas kinematics for ten z<0.2 type~2 `obscured' quasars (log [L(AGN)/(erg/s)]>~45)…
The Wide Integral Field Infrared Spectrograph: Commissioning Results and On-sky Performance
Suresh Sivanandam, Dae-Sik Moon, R. Elliot Meyer +11
We have recently commissioned a novel infrared ( m) integral field spectrograph (IFS) called the Wide Integral Field Infrared Spectrograph (WIFIS). WIFIS is a unique in…
Storm in a Teacup: X-ray view of an obscured quasar and superbubble
G. B. Lansbury, M. E. Jarvis, C. M. Harrison +5
We present the X-ray properties of the 'Teacup AGN' (SDSS J1430+1339), a type 2 quasar which is interacting dramatically with its host galaxy. Spectral modelling of the c…
