Characterising the Far-infrared Properties of Distant X-ray Detected AGNs: Evidence for Evolution in the Infrared--X-ray Luminosity Ratio
J. R. Mullaney, D. M. Alexander, M. Huynh +2
(Abridged) We investigate the far-infrared properties of X-ray sources detected in the Chandra Deep Field-South (CDF-S) survey using the ultra-deep 70um and 24um Spitzer observatio…
The Chandra Deep Protocluster Survey: Point-Source Catalogs for a 400 ks Observation of the z = 3.09 Protocluster in SSA22
B. D. Lehmer, D. M. Alexander, S. C. Chapman +7
We present X-ray point-source catalogs for a deep 400 ks Chandra ACIS-I exposure of the SSA22 field. The observations are centred on a z = 3.09 protocluster, which is populated by…
AGN with strong forbidden high-ionisation lines selected from the Sloan Digital Sky Survey
Jonathan M. Gelbord, James R. Mullaney, Martin J. Ward
We have defined a sample of 63 AGN with strong forbidden high-ionisation line (FHIL) emission. These lines, with ionisation potentials >~ 100eV, respond to a portion of the spectru…
The Seyfert AGN RX J0136.9-3510 and the Spectral State of Super Eddington Accretion Flows
C. Jin, C. Done, M. Ward +2
We have carried out a survey of long 50ks XMM-Newton observations of a sample of bright, variable AGN. We found a distinctive energy dependence of the variability in RXJ0136.9-3510…
