Overdensity around high redshift radio galaxies, quasars, and Hot DOGs as a function of redshift. We highlight the studies based on LBGs around quasars (magenta triangles, Zheng et al. 2006; Morselli et al. 2014; Balmaverde et al. 2017; García-Vergara et al. 2017), around radio galaxies (magenta circles, Miley et al. 2004; Intema et al. 2006; Overzier et al. 2008) and Hot DOGs (magenta star, this work), those based on LAEs around quasars (blue triangles, García-Vergara et al. 2019), radio galaxies (blue circles, Venemans et al. 2002, 2004, 2005, 2007; Miley et al. 2004), and Hot DOGs (blue star, Ginolfi et al. 2022) and a study based on DRGs around Hot DOGs (cyan star, Luo et al. 2022). Overdensities of 24 μm sources around high redshift radio galaxies are also shown (grey dot, Mayo et al. 2012). The red solid horizontal line indicates no overdensity. (*: These studies defined the overdensity instead as δ = Nfound/Nexpected − 1. We transformed these estimates to reflect our definition of δ before adding them to the figure.)
