Caption

In this visualization, each dot represents a gas parcel with a mass approximately 1,000 times that of the Sun in the simulation of the cosmic Dark Ages. The left and right panels compare the cold and warm dark matter scenarios, respectively. The color represents the gas temperature, with yellow, red, and black corresponding roughly to 200 , 50 , and 20  Kelvin, respectively. Time progresses from top to bottom, showing the evolution of gas structures during the cosmic Dark Ages.
