The blue points are DM pseudo-particles (M = 3 x 10-4 Msun), while the white dots (initially obscured) are the PBHs, each with a mass of 30 Msun.
The pair decouples shortly before matter radiation equality, with an initial semi-major of a = 0.01 pc. The movies show initial eccentricities of e = 0.95 and e = 0.995.
