Radio stacking reveals evidence for star formation in the host galaxies of X-ray selected active galactic nuclei at z<1
C. M. Pierce, D. R. Ballantyne, R. J. Ivison
Nuclear starbursts may contribute to the obscuration of active galactic nuclei (AGNs). The predicted star formation rates are modest, and, for the obscured AGNs that form the X-ray…
Host galaxy colour gradients and accretion disc obscuration in AEGIS z~1 X-ray-selected active galactic nuclei
C. M. Pierce, J. M. Lotz, S. Salim +7
We describe the effect of AGN light on host galaxy optical and UV-optical colours, as determined from X-ray-selected AGN host galaxies at z~1, and compare the AGN host galaxy colou…
The Effects of an AGN on Host Galaxy Colour and Morphology Measurements
C. M. Pierce, J. M. Lotz, J. R. Primack +11
We assess the effects of simulated active galactic nuclei (AGNs) on the colour and morphology measurements of their host galaxies. To test the morphology measurements, we select a…
Host galaxy morphologies of X-ray selected AGN: assessing the significance of different black hole fueling mechanisms to the accretion density of the Universe at z~1
A. Georgakakis, A. L. Coil, E. S. Laird +7
We use morphological information of X-ray selected AGN hosts to set limits on the fraction of the accretion density of the Universe at z~1 that is not likely to be associated with…
