Fig. 4.


Ratio of black hole to galaxy mass as a function of redshift. The MBH/M ratios of WISE J1042+1641 are shown as double circles and are color-coded according to the magnification factors of μ = 53 (red) and 122 (blue). The black solid line indicates the MBH/M sequence of radio-loud AGNs in McLure et al. (2006), followed by unobscured AGNs shown as red and blue open circles for lensed and non-lensed objects, respectively (Peng et al. 2006b). The blue and pink filled squares denote X-ray obscured SMGs and local ULIRGs, respectively (Alexander et al. 2008). SDSS luminous quasars at z ∼ 4 (i.e., SDSS J1310−0055 and SDSS J1446−0101) in Targett et al. (2012) are denoted with light blue open circles. The green open circle denotes an X-ray selected unobscured AGN at the massive end, CDI-947 (Trakhtenbrot et al. 2015), and the green line is a scaled sequence of McLure et al. (2006) to the source. The gray area is the typical mass ratio in the local Universe (Marconi & Hunt 2003).
