SDSS J1056+5516: A Triple AGN or an SMBH Recoil Candidate?
Eleni Kalfountzou, M. Santos Lleo, M. Trichas
We report the discovery of a kiloparsec-scale triple supermassive black hole system at : SDSS J1056+5516, discovered by our systematic search for binary quasars. The syste…
Observational evidence that positive and negative AGN feedback depends on galaxy mass and jet power
E. Kalfountzou, J. A. Stevens, M. J. Jarvis +6
Several studies support the existence of a link between the AGN and star formation activity. Radio jets have been argued to be an ideal mechanism for direct interaction between the…
The Largest X-ray Selected Sample of z>3 AGNs: C-COSMOS & ChaMP
E. Kalfountzou, F. Civano, M. Elvis +2
We present results from an analysis of the largest high-redshift (z > 3) X-ray-selected active galactic nucleus (AGN) sample to date, combining the Chandra C-COSMOS and ChaMP surve…
The suppression of star formation by powerful active galactic nuclei
M. J. Page, M. Symeonidis, J. D. Vieira +75
The old, red stars which constitute the bulges of galaxies, and the massive black holes at their centres, are the relics of a period in cosmic history when galaxies formed stars at…
Empirical Links between XRB and AGN accretion using the complete z<0.4 spectroscopic CSC/SDSS Catalog
Markos Trichas, Paul Green, Anca Constantin +8
Striking similarities have been seen between accretion signatures of Galactic X-ray binary (XRB) systems and active galactic nuclei (AGN). XRB spectral states show a V-shaped corre…
The Herschel PEP/HerMES Luminosity Function. I: Probing the Evolution of PACS selected Galaxies to z~4
C. Gruppioni, F. Pozzi, G. Rodighiero +100
We exploit the deep and extended far infrared data sets (at 70, 100 and 160 um) of the Herschel GTO PACS Evolutionary Probe (PEP) Survey, in combination with the HERschel Multi tie…
