Do the Most Massive Black Holes at Grow via Major Mergers?
M. Mechtley, K. Jahnke, R. A. Windhorst +11
The most frequently proposed model for the origin of quasars holds that the high accretion rates seen in luminous active galactic nuclei are primarily triggered during major merger…
Interacting galaxies in the nearby Universe: only moderate increase of star formation
Johan H. Knapen, Mauricio Cisternas, Miguel Querejeta
We investigate the influence of interactions on the star formation by studying a sample of almost 1500 of the nearest galaxies, all within a distance of ~45 Mpc. We define the mass…
The Odd Offset between the Galactic Disk and Its Bar in NGC 3906
Bonita de Swardt, Kartik Sheth, Taehyun Kim +27
We use mid-infrared 3.6 and 4.5microns imaging of NGC 3906 from the Spitzer Survey of Stellar Structure in Galaxies (S4G) to understand the nature of an unusual offset between its…
Starbursts are preferentially interacting: confirmation from the nearest galaxies
Johan H. Knapen, Mauricio Cisternas
We complement a recent ApJ Letter by Luo et al. by comparing the fraction of starburst galaxies which are interacting with the overall fraction of interacting galaxies in the nearb…
Comparative internal kinematics of the HII regions in interacting and isolated galaxies: implications for massive star formation modes
Javier Zaragoza-Cardiel, John E. Beckman, Joan Font +7
We have observed 10 interacting galaxy pairs using the Fabry-Perot interferometer GHFaS (Galaxy H Fabry-Perot system) on the William Herschel Telescope (WHT) at t…
H-alpha kinematics of S4G spiral galaxies-II. Data description and non-circular motions
Santiago Erroz-Ferrer, Johan H. Knapen, Ryan Leaman +15
We present a kinematical study of 29 spiral galaxies included in the Spitzer Survey of Stellar Structure in Galaxies, using Halpha Fabry-Perot data obtained with the Galaxy Halpha…
