We developed a geometry for the clumps swirling around super-massive black holes, sometimes hiding them from us.
In this fly-through 3d video you can see these clumps around a black hole. These clumps can hide the luminous accretion disk and X-ray emission from us, but also glow in infrared radiation. Sometimes a clump moves, and unveils the center -- from such events and the fraction of obscured black holes we constructed this model geometry.
The blue disk in the center is for orientation only, and much larger than the accretion disk.
The cloud population is consistent with existing infrared models (CLUMPY, Nenkova+02). However, we find that a inner torus ring component is required.
