Hot-Dust-Poor Type 1 Active Galactic Nuclei in the COSMOS Survey
Heng Hao, Martin Elvis, Francesca Civano +13
We report a sizable class of type 1 active galactic nuclei (AGNs) with unusually weak near-infrared (1-3μm) emission in the XMM-COSMOS type 1 AGN sample. The fraction of these "hot…
Witnessing the key early phase of quasar evolution: an obscured AGN pair in the interacting galaxy IRAS 20210+1121
E. Piconcelli, C. Vignali, S. Bianchi +6
We report the discovery of an active galactic nucleus (AGN) pair in the interacting galaxy system IRAS 20210+1121 at z = 0.056. An XMM-Newton observation reveals the presence of an…
A Runaway Black Hole in COSMOS: Gravitational Wave or Slingshot Recoil?
F. Civano, M. Elvis, G. Lanzuisi +39
We present a detailed study of a peculiar source in the COSMOS survey at z=0.359. Source CXOCJ100043.1+020637 (CID-42) presents two compact optical sources embedded in the same gal…
