The role of bars in AGN fueling in disk galaxies over the last seven billion years
Mauricio Cisternas, Kartik Sheth, Mara Salvato +3
We present empirical constraints on the influence of stellar bars on the fueling of active galactic nuclei (AGNs) out to z=0.84 using a sample of X-ray-selected AGNs hosted in lumi…
IRAC Near-Infrared Features in the Outer Parts of S4G Galaxies
Seppo Laine, Johan H. Knapen, Juan-Carlos Munoz-Mateos +26
We present a catalogue and images of visually detected features, such as asymmetries, extensions, warps, shells, tidal tails, polar rings, and obvious signs of mergers or interacti…
Optical imaging for the Spitzer Survey of Stellar Structure in Galaxies. Data release and notes on interacting galaxies
Johan H. Knapen, Santiago Erroz-Ferrer, Javier Roa +4
(Abridged) The Spitzer Survey for Stellar Structure in Galaxies (S4G) and its more recently approved extension will lead to a set of 3.6 and 4.5 micron images for 2829 galaxies, wh…
The bulk of the black hole growth since z~1 occurs in a secular universe: No major merger-AGN connection
Mauricio Cisternas, Knud Jahnke, Katherine J. Inskip +21
What is the relevance of major mergers and interactions as triggering mechanisms for active galactic nuclei (AGN) activity? To answer this longstanding question, we analyze 140 XMM…
