PKS0347+05: a radio-loud/radio-quiet double AGN system triggered in a major galaxy merger
C. Tadhunter, C. Ramos Almeida, R. Morganti +4
We present optical, infrared and radio observations of the powerful FRII radio source PKS0347+05 (z=0.3390), and demonstrate that it is a rare example of a radio-loud/radio-quiet d…
Secular evolution and a non-evolving black hole to galaxy mass ratio in the last 7 Gyr
Mauricio Cisternas, Knud Jahnke, Angela Bongiorno +6
We present new constraints on the ratio of black hole (BH) mass to total galaxy stellar mass at 0.3<z<0.9 for a sample of 32 type-1 active galactic nuclei (AGNs) from the XMM-COSMO…
PKS 1814-637: a powerful radio-loud AGN in a disk galaxy
R. Morganti, J. Holt, C. Tadhunter +5
We present a detailed study of PKS1814-637, a rare case of powerful radio source (P_5 GHz = 4.1 x 10^25 W/Hz) hosted by a disk galaxy. Optical images have been used to model the ho…
Resolving the dynamical mass of a z~1.3 QSO host galaxy using SINFONI and Laser Guide Star assisted Adaptive Optics
Katherine J. Inskip, Knud Jahnke, Hans-Walter Rix +1
Recent studies of the tight scaling relations between the masses of supermassive black holes and their host galaxies have suggested that in the past black holes constituted a large…
Clear detection of dusty torus signatures in a Weak-Line Radio Galaxy: the case of PKS 0043-42
Cristina Ramos Almeida, Daniel Dicken, Clive Tadhunter +4
We report the clearest detection to date of dusty torus signatures in a Weak-Line Radio Galaxy (WLRG). The deep Spitzer InfraRed Spectrograph (IRS) rest-frame mid-infrared (MIR) sp…
Starburst radio galaxies: general properties, evolutionary histories and triggering
C. Tadhunter, J. Holt, R. Gonzalez Delgado +6
In this paper we discuss the results of a programme of spectral synthesis modelling of a sample of starburst radio galaxies in the context of scenarios for the triggering of the ac…
