BLACK HOLES. “We find that the seeds of massive black holes may be much more common than previously considered in overdense regions of the early Universe, with a co-moving number density up to 10(-3) per cubic megaparsec.” https://www.nature.com/articles/s41586-019-0873-4 View in LinkedIn

DUTCH DOLLS. “Standard cold dark-matter cosmologies predict that large-scale structure forms hierarchically. Smaller objects that form at early times subsequently merge and grow into larger objects.” https://www.nature.com/articles/s41586-019-0873-4 View in LinkedIn

SUPERMASSIVE BLACK HOLES. “The existence of supermassive black holes with masses of around 19(9) Mʘ (where Mʘ is the solar mass) only 800 Myr after the Big Bang indicates that there must have been an early intense convergence of mass in ‘rare’ locations, occurring only roughly ten times per co-moving cubic gigaparsec.” https://www.nature.com/articles/s41586-019-0873-4 View in LinkedIn

SIMULATION CONTEXT. “We analyse the region from the Renaissance simulation suite that is centred on the densest cosmological co-moving volume (133.6 Mpc3), which contains 822 galaxies at its ending redshift of z = 15 (270 Myr after the Big Bang).” https://www.nature.com/articles/s41586-019-0873-4 View in LinkedIn

THE DATA SET. “There are 670 atomic-cooling haloes, ten of which are metal-free and have not hosted prior star formation. The remaining atomic-cooling haloes have formed stars prompted by either H2 or metal-line cooling and are not conducive to the formation of SMSs (and subsequently direct-collapse black holes, DCBHs).” (SMSs = supermassive black holes). https://www.nature.com/articles/s41586-019-0873-4 View in LinkedIn

THE ENRICHED AREA. “Both haloes assemble in a region 10–25 kpc away from a group of young galaxies that have photo-ionized, photo-heated and chemically enriched the surrounding environments.” https://www.nature.com/articles/s41586-019-0873-4 View in LinkedIn
