1keV 1022 cm-2 penetration
think of a Seyfert AGN at 100 pc
High opacity effect of metal enriched gas
Density-temperature (left) and column density-radius (right) profiles for zero and solar metallicity cases at z=14.95 (top) and z=14.54 (bottom).
Low (103 J21) and high (105J21) UV bg. cases at z=14.95 (left), 14.86 (middle), and 14.78 (right).
Low UV bg, at z=14.95!!!
Strong UV background prevents growth to a SMBH!
X-ray feedback/BH growth self-regulating
High UV bg case,
