X-ray nuclear activity in S4G barred galaxies: No link between bar strength and co-occurrent supermassive black hole fueling
Mauricio Cisternas, Dimitri Gadotti, Johan H. Knapen +23
Stellar bars can lead to gas inflow toward the center of a galaxy and stimulate nuclear star formation. However, there is no compelling evidence on whether they also feed a central…
Spectral Energy Distributions of Type 1 AGN in the COSMOS Survey I - The XMM-COSMOS Sample
M. Elvis, H. Hao, F. Civano +39
The "Cosmic Evolution Survey" (COSMOS) enables the study of the Spectral Energy Distributions (SEDs) of Active Galactic Nuclei (AGN) because of the deep coverage and rich sampling…
The Chandra COSMOS Survey: III. Optical and Infrared Identification of X-ray Point Sources
F. Civano, M. Elvis, M. Brusa +29
The Chandra COSMOS Survey (C-COSMOS) is a large, 1.8 Ms, Chandra program that has imaged the central 0.9 deg^2 of the COSMOS field down to limiting depths of 1.9 10^-16 erg cm^-2 s…
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…
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…
Massive Galaxies in COSMOS: Evolution of Black hole versus bulge mass but not versus total stellar mass over the last 9 Gyrs?
Knud Jahnke, Angela Bongiorno, Marcella Brusa +22
We constrain the ratio of black hole (BH) mass to total stellar mass of type-1 AGN in the COSMOS survey at 1<z<2. For 10 AGN at mean redshift z~1.4 with both HST/ACS and HST/NICMOS…
