Galaxy cluster map shows remnants of the Black Hole splitting Big Bang, creating dual BH Herbig Haro systems for star/ galaxy formation. and the Lyman Apha forest.
A galaxy cluster map portraying the density of galaxies members in the massive cluster SPT-CLJ0421. Astronomers studying five such clusters in the epoch about 4.5 billion years after the big bang conclude that their star formation is quenched. Symbols show the positions of individual galaxies and the cross marks the position of the SPT detection. Credit: Strazzullo et al. 2019.
Massive clusters of galaxies, some with more mass than a hundred Milky Way galaxies, have been detected from cosmic epochs as early as about three billion years after the big bang.

See Above: The well known 6 massive early galaxies seem to be ( by Q-FFF model) massive Big Bang Black Holes searching for a partner to form a dual Herbig Haro star forming system.
above: One example is MRG-M1341, at upper right. It looks distorted by the “funhouse mirror” optical effects of lensing. In contrast, the purple blob to the left of the galaxy is an example of a dust-and-gas-rich galaxy.
