VizieR Online Data Catalog: X-ray active galactic nucleus at z~0.4 (Noordeh+, 2020)

Our study includes seven galaxy clusters drawn from the MAssive Cluster Survey (MACS, Ebeling et al. 2010MNRAS.407...83E) that are visible from the south with redshifts between z=0.355 and 0.451 and M₅₀₀ values ranging from 5.5x10¹⁴ to 2.2x10¹⁵M_ȯ. These are some of the most massive and X-ray luminous clusters known, where we would expect any environmental influence on AGN activity to be most pronounced. We select a narrow redshift band in order to control for possible redshift evolution in the cluster AGN population. This particular band is well suited to VIMOS (VIsible Multi-Object Spectrograph) spectroscopy (see Section 2.5). All clusters have been observed with the Advanced CCD Imaging Spectrometer (ACIS) aboard the Chandra X-ray Observatory and have multiband Subaru Suprime-Cam (B_J, V_J, R_C, I_C, i⁺, z⁺) photometry from the Weighing the Giants Survey (WtG; von der Linden et al. 2014MNRAS.439....2V).
