The Spitzer mid-infrared AGN survey. I - optical and near-infrared spectroscopy of candidate obscured and normal AGN selected in the mid-infrared
M. Lacy, S. E. Ridgway, E. L. Gates +8
We present the results of a program of optical and near-infrared spectroscopic follow-up of candidate Active Galactic Nuclei (AGN) selected in the mid-infrared. This survey selects…
Narrow-line region gas kinematics of 24,264 optically-selected AGN: the radio connection
J. R. Mullaney, D. M. Alexander, S. Fine +3
Using a sample of 24264 optically selected AGNs from the SDSS DR7 database, we characterise how the profile of the [OIII] emission line relates to bolometric luminosity (L_Bol), Ed…
Concurrent Supermassive Black Hole and Galaxy Growth: Linking Environment and Nuclear Activity in z = 2.23 H-alpha Emitters
B. D. Lehmer, A. B. Lucy, D. M. Alexander +9
We present results from a ~100 ks Chandra observation of the 2QZ Cluster 1004+00 structure at z = 2.23 (hereafter, 2QZ Clus). 2QZ Clus was originally identified as an overdensity o…
No clear submillimetre signature of suppressed star formation amongst X-ray luminous AGNs
C. M. Harrison, D. M. Alexander, J. R. Mullaney +18
Many theoretical models require powerful active galactic nuclei (AGNs) to suppress star formation in distant galaxies and reproduce the observed properties of today's massive galax…
The evolutionary connection between QSOs and SMGs: molecular gas in far-infrared luminous QSOs at z ~ 2.5
J. M. Simpson, Ian Smail, A. M. Swinbank +23
We present IRAM Plateau de Bure Interferometer observations of the 12CO(3-2) emission from two far-infrared luminous QSOs at z ~ 2.5 selected from the Herschel-ATLAS survey. These…
Energetic galaxy-wide outflows in high-redshift ultra-luminous infrared galaxies hosting AGN activity
C. M. Harrison, D. M. Alexander, A. M. Swinbank +10
We present integral field spectroscopy observations, covering the [O III]4959,5007 emission-line doublet of eight high-redshift (z=1.4-3.4) ultra-luminous infrared galaxies (ULIRGs…
