Abstract Coupling of black hole mass to the cosmic expansion has been suggested as a possible path understanding dark energy content Universe. We test this hypothesis by comparing supermassive (SMBH) density at z = 0 total accreted in active galactic nuclei (AGN) since 6, constrain how much SMBH can arise from cosmologically coupled growth, opposed growth accretion. Using an estimate local ≈1.0 × 10 6 M ⊙ Mpc −1 , radiative accretion efficiency, η range 0.05 < 0.3, and observed AGN...
The assembly of supermassive black hole (SMBH) mass ($M_{\bullet}$) and stellar ($M_{*}$) in galaxies can be studied via the redshift evolution $M_{\bullet}-M_{*}$ relation, but ways which selection bias physical channels affect this are uncertain. To address this, we compare relation for local massive ($M_{*}>10^{10.5}$M$_{\odot}$) quiescent early-type (ETGs) to that ETGs hosting active galactic nuclei (AGN) at $z\sim0.8$. restrictions on galaxy type limit may connect two relations. For...

We test this hypothesis by comparing supermassive (SMBH) density at $z=0$ total accreted in AGN since $z=6$, constrain how much SMBH can arise from cosmologically-coupled growth, opposed growth accretion.
