摘要: A perfect irrotational fluid with the equation of state dust, Irrotational Dark Matter (IDM), is incapable virializing and instead forms a cosmoskeleton filaments supermassive black holes at joints. This stark difference from standard cold dark matter (CDM) scenario arises because IDM must exhibit potential flow all times, preventing shell-crossing occurring. applicable to general non-oscillating scalar-field theories small sound speed. Our model combined CDM components thereby provides solution problem forming observed billion-solar-mass redshifts six higher. In particular, as result reduced vortical flow, growth expected be more rapid later times compared scenario.
