VizieR Online Data Catalog: Hyper-luminous X-ray sources from SDSS and CSC2 (Barrows+, 2019)
Abstract
Our initial galaxy sample is drawn from the catalog of SDSS detections that are classified as galaxies and with photometric redshifts derived by the SDSS pipeline. We use the galaxy photometric redshift catalog from Data Release 7 (DR7; Abazajian+ 2009, II/294), but also include any additional galaxies detected in subsequent data releases through DR14 (Abolfathi+ 2018ApJS..235...42A).
We use the Chandra Source Catalog Version 2 (Evans+, 2019, IX/57) Master Source Catalog as our parent sample of X-ray sources detected at >3σ significance. (3 data files).- Publication:
