Recent studies have suggested that during their coalescence, binary supermassive black holes (SMBHs) experience typical gravitational recoil velocities that may be as large as 100 km s-1. These velocities exceed the escape velocity vesc from typical dark matter (DM) halos at high redshift (z 6), and therefore put constraints on scenarios in which early SMBHs grow at the centers of DM halos. Here we quantify these constraints for the most distant known SMBH, with an inferred mass in excess of… Expand

X-ray emission from high-redshift miniquasars: self-regulating the population of massive black holes through global warming
Observations of high-redshift quasars at z � 6 imply that supermassive black holes (SMBHs) with masses M � 10 9 M⊙ were in place less than 1 Gyr after the Big Bang. If these SMBHs assembled fromExpand
Spin, accretion, and the cosmological growth of supermassive black holes
If supermassive black holes (SMBHs) are the energy sources that power quasars and active galactic nuclei (AGNs), then QSO SDSS 1148+5251, the quasar with the highest redshift (zQSO = 6.43), hosts anExpand

Quasars at z = 6 : The survival of the fittest
The Sloan Digital Sky Survey has detected luminous quasars at very high redshift, z > 6. Follow-up observations indicate that at least some of these quasars are powered by supermassive black holesExpand
Chasing the observational signatures of seed black holes at z > 7: candidate statistics
Supermassive black holes (SMBHs) of 10^9-10^10 Msun were already in place ~13 Gyr ago, at z>6. Super-Eddington growth of low-mass BH seeds (~100 Msun) or less extreme accretion onto ~10^5 Msun seedsExpand

The effect of baryonic streaming motions on the formation of the first supermassive black holes
Observations of quasars at redshifts z > 6 reveal that 10^9 Msol supermassive black holes (SMBHs) had already formed when the Universe was 20. This is the regime where baryonic streaming motions--theExpand
