Morphologies of z~0.7 AGN Host Galaxies in CANDELS: No trend of merger incidence with AGN luminosity
C. Villforth, F. Hamann, D. J. Rosario +24
The processes that trigger Active Galactic Nuclei (AGN) remain poorly understood. While lower luminosity AGN may be triggered by minor disturbances to the host galaxy, stronger dis…
Host galaxies of luminous z0.6 quasars: Major mergers are not prevalent at the highest AGN luminosities
C. Villforth, T. Hamilton, M. M. Pawlik +10
Galaxy interactions are thought to be one of the main triggers of Active Galactic Nuclei (AGN), especially at high luminosities, where the accreted gas mass during the AGN lifetime…
The host galaxies of FeLoBAL quasars at z0.9 are not dominated by recent major mergers
C. Villforth, H. Herbst, F. Hamann +4
Theoretical models have suggested an evolutionary model for quasars, in which most of luminous quasars are triggered by major mergers. It is also postulated that reddening as well…
SDSSJ143244.91+301435.3: a link between radio-loud narrow-line Seyfert 1 galaxies and compact steep-spectrum radio sources?
A. Caccianiga, S. Antón, L. Ballo +12
We present SDSSJ143244.91+301435.3, a new case of radio-loud narrow line Seyfert 1 (RL NLS1) with a relatively high radio power (P1.4GHz=2.1x10^25 W Hz^-1) and large radioloudness…
Basic properties of Narrow-Line Seyfert 1 Galaxies with Relativistic Jets
L. Foschini, E. Angelakis, G. Bonnoli +25
We present the preliminary results of a survey performed with Swift to observe a sample of radio-loud Narrow-Line Seyfert 1 Galaxies (RLNLS1s). Optical-to-X-ray data from Swift are…
