VizieR Online Data Catalog: Chandra obs. of SDSS AGN pairs at zmed~0.1 (Hou+,
Abstract
We start from the 1286 optically selected AGN pairs or multiples at a median redshift z~0.1 from Liu+ (2011, J/ApJ/737/101).
Our final sample consists of 67 AGN pairs with Chandra archival observations from the optically selected AGN pairs. Among them, 22 pairs are observed as the prime target. These include one triple AGN candidate, SDSS J0858+1822, observed in Chandra Program GO-14700279 (PI: Liu); one triple AGN candidate, SDSS J1027+1749, optically identified by Liu+ 2011ApJ...736L...7L ; and five systems of AGN pairs studied by Hou+ (2019ApJ...882...41H). The remaining 45 pairs were serendipitously observed. (2 data files).- Publication:
