New insights from deep VLA data on the potentially recoiling black hole CID-42 in the COSMOS field
Mladen Novak, Vernesa Smolcic, Francesca Civano +12
We present deep 3 GHz VLA observations of the potentially recoiling black hole CID-42 in the COSMOS field. This galaxy shows two optical nuclei in the HST/ACS image and a large vel…
Clustering properties of moderate luminosity X-ray selected Type 1 and Type 2 AGN at z~3
V. Allevato, A. Finoguenov, F. Civano +11
We investigate, for the first time at z~3, the clustering properties of 189 Type 1 and 157 Type 2 X-ray active galactic nuclei (AGN) of moderate luminosity (log<Lbol> = 45.3 erg/s)…
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…
Inter-comparison of Radio-Loudness Criteria for Type 1 AGNs in the XMM-COSMOS Survey
Heng Hao, Mark T. Sargent, Martin Elvis +21
Limited studies have been performed on the radio-loud fraction in X-ray selected type 1 AGN samples. The consistency between various radio-loudness definitions also needs to be che…
Mid-Infrared Selected Quasars I: Virial Black Hole Mass and Eddington Ratios
Y. Sophia Dai, Martin Elvis, Jacqueline Bergeron +6
We provide a catalog of 391 mid-infrared-selected (MIR, 24m) broad-emission-line (BEL, type 1) quasars in the 22 deg SWIRE Lockman Hole field. This quasar sample is selected…
Constraints on the outer radius of the broad emission line region of active galactic nuclei
Hermine Landt, Martin J. Ward, Martin Elvis +1
Here we present observational evidence that the broad emission line region (BELR) of active galactic nuclei (AGN) generally has an outer boundary. This was already clear for source…
