Collision of clouds from the broad-line region in super-Eddington supermassive black holes

We present results from hydrodynamic, relativistic simulations of the collision of clouds from the broad-line region. In our model, the clouds orbit a super-Eddington supermassive black hole (SMBH). The clouds move at supersonic speeds through the dense wind launched from the SMBH's accretion disk. Collision between the clouds can produce strong electromagnetic flares that reveal some properties such as their mass, volume, and speed. We analyze spherical and fractal clouds colliding with different impact factors. Our results provide insight into this unexplored phenomenon.
