Soft X-ray and Ultraviolet Emission Relations in Optically Selected AGN Samples
Iskra Strateva, Niel Brandt, Donald Schneider +2
Using a sample of 228 optically selected Active Galactic Nuclei (AGNs) in the 0.01-6.3 redshift range with a high fraction of X-ray detections (81-86%), we study the relation betwe…
Active Galactic Nuclei in the Sloan Digital Sky Survey: I. Sample Selection
Lei Hao, Michael A. Strauss, Christy A. Tremonti +18
We have compiled a large sample of low-redshift active galactic nuclei (AGN) identified via their emission line characteristics from the spectroscopic data of the Sloan Digital Sky…
Active Galactic Nuclei in the Sloan Digital Sky Survey: II. Emission-Line Luminosity Function
Lei Hao, Michael A. Strauss, Xiaohui Fan +18
The emission line luminosity function of active galactic nuclei (AGN) is measured from about 3000 AGN included in the main galaxy sample of the Sloan Digital Sky Survey within a re…
