Dressed Primordial Black Hole Binaries - Animations

Animations showing the evolution of a binary of two primordial black holes (PBH), each dressed in a local dark matter (DM) halo.<br>The blue points are DM pseudo-particles (M = 3 x 10^-4M_sun), while the white dots (initially obscured) are the PBHs, each with a mass of 30 M_sun.<br>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. <br>Further details can be found at the associated GitHub repo - https://github.com/bradkav/BlackHolesDarkDress.<br>

本动画展示了由两个原初黑洞（primordial black holes, PBH）组成的双星系统的演化过程，每个原初黑洞均被局域暗物质（dark matter, DM）晕所包裹。
图中蓝色点代表暗物质赝粒子 (DM pseudo-particles)，其质量为3×10^-4倍太阳质量（M_sun）；而最初被遮蔽的白色点则为原初黑洞，单个原初黑洞的质量为30倍太阳质量（M_sun）。
该双星系统在物质-辐射相等时期前不久完成解耦，初始半长轴为a=0.01秒差距（pc）。本动画分别展示了初始偏心率为e=0.95与e=0.995的演化场景。
