SURPRISE FINDING. “It has been found that the brightest quasars do not necessarily live in the highest density regions (rather the strongest correlation was found to be with low tidal field regions) of the early universe suggesting that their descendants may not necessarily be among the most massive haloes at z = 0.” https://lnkd.in/dX4w36NJ View in LinkedIn

QUASAR OFFSPRING. “These studies indicate that quasar descendants are most likely not to live in privileged sites.” https://lnkd.in/dX4w36NJ View in LinkedIn

THE MIGHTY INSECT. “The most advanced social insects—ants, termites, many species of bees and wasp—make up only about 3 percent of the known species of animals on earth. But on the land they make up in most habitats upwards of 50 percent of the biomass.” (The remarkable Professor EO Wilson) https://lnkd.in/dAbrgVEW View in LinkedIn

STAR GENEOLOGY. “Our main finding is that the rare quasars with the most massive black holes do not have the most massive low-redshift descendants.” https://lnkd.in/dX4w36NJ View in LinkedIn

SURPRISE FINDING. “We further find that for similar range of halo masses at z = 8, the halo masses of the low-redshift descendants of the least massive high-redshift black holes at z = 0 have a distribution similar to those of the descendants of most massive high-redshift black holes. Consistent with our results…the most luminous quasars do not live in the most massive haloes.” https://lnkd.in/dX4w36NJ View in LinkedIn

ANCIENT GIANT BLACK HOLES. “Observations of the most luminous quasars at redshift z > 6 reveal the existence of numerous supermasssive black holes (>19(9)M⊙) already in place about 12 billion years ago.” https://lnkd.in/dHcpNrnR View in LinkedIn

12 BN YEAR OLD STRUCTURES. “In addition, the interstellar medium of the galaxies hosting these black holes are observed to be chemically mature systems, with metallicities (Z > Z⊙) and dust masses (>10(8) M⊙) similar to that of more evolved, local galaxies.” https://lnkd.in/dHcpNrnR View in LinkedIn

UNRESOLVED. “The connection between the rapid growth of the first supermassive black holes and the fast chemical evolution of the host galaxy is one of the most puzzling issues for theoretical models.” https://lnkd.in/dHcpNrnR View in LinkedIn

THE INVENTORY. “Up to ~40 supermassive black holes (SMBHs) of >10(9) M⊙ have been observed till date, which are believed to power the optically bright quasars (>10(47) erg s−1) observed at z > 5.” https://lnkd.in/dHcpNrnR View in LinkedIn
