Large-scale structure

A slice through the full Lumina box showing the cosmic web structure at z=3.

$A slice showing the HII gas fraction at z = 7. Bright regions are ionized bubbles around galaxies, while dark regions are still neutral.$

Hydrogen reionization

A slice showing the HII gas fraction at z = 7. Bright regions are ionized bubbles around galaxies, while dark regions are still neutral.

$A slice showing the HeIII gas fraction at z = 4. Blue regions represent already reionized regions. The ionized and neutral regions are both larger than for hydrogen reionization, due to the more energetic photons and rarer sources responsible for HeII reionization.$

HeII reionization

A slice showing the HeIII gas fraction at z = 4. Blue regions represent already reionized regions. The ionized and neutral regions are both larger than for hydrogen reionization, due to the more energetic photons and rarer sources responsible for HeII reionization.

$Red regions indicate areas with higher baryon to dark matter fraction while blue regions repsents regions with lower fraction at redshift z = 23. These variations are caused by the different initial power spectra used in Lumina. The array represent the large-scale relative streaming velocity between both components.$

Isocurvature perturbations and streaming velocity

Red regions indicate areas with higher baryon to dark matter fraction while blue regions repsents regions with lower fraction at redshift z = 23. These variations are caused by the different initial power spectra used in Lumina. The array represent the large-scale relative streaming velocity between both components.
