Luminous and obscured quasars and their host galaxies
Agnese Del Moro, David M. Alexander, Franz E. Bauer +4
The most heavily-obscured, luminous quasars might represent a specific phase of the evolution of actively accreting supermassive black holes and their host galaxies, possibly relat…
Identifying the subtle signatures of feedback from distant AGN using ALMA observations and the EAGLE hydrodynamical simulations
J. Scholtz, D. M. Alexander, C. M. Harrison +10
We present sensitive 870m continuum measurements from our ALMA programmes of 114 X-ray selected AGN in the CDF-S and COSMOS fields. We use these observations in combination with…
Deep ALMA photometry of distant X-ray AGN: improvements in star formation rate constraints, and AGN identification
F. Stanley, C. M. Harrison, D. M. Alexander +5
We present the star formation rates (SFRs) of a sample of 109 galaxies with X-ray selected active galactic nuclei (AGN) with moderate to high X-ray luminosities (L(2-8keV)= 10^42-1…
The mean star formation rates of unobscured QSOs: searching for evidence of suppressed or enhanced star formation
F. Stanley, D. M. Alexander, C. M. Harrison +15
We investigate the mean star formation rates (SFRs) in the host galaxies of ~3000 optically selected QSOs from the SDSS survey within the Herschel-ATLAS fields, and a radio-luminou…
A New Compton-thick AGN in our Cosmic Backyard: Unveiling the Buried Nucleus in NGC 1448 with NuSTAR
A. Annuar, D. M. Alexander, P. Gandhi +22
NGC 1448 is one of the nearest luminous galaxies ( 10) to ours ( 0.00390), and yet the active galactic nucleus (AGN) it hosts was only recent…
