| « Black holes mass assembly in a non-Gaussian Universe » |

Primordial non-Gaussianities provide an important test of inflationary models. Although the Planck cosmic microwave background experiment has produced strong limits on non-Gaussinities on scales of clusters, there is still room for considerable non-Gaussianity on galactic scales.
I will explore the consequences of non-Gaussianities on the low-mass end of the galaxy mass function and the potential impact on the reionization history. As you know, supermassive black holes ARE SUPER COOL, so I will explore the possibility that scale-dependent non-Gaussian primordial fluctuations may ease the assembly of supermassive black holes. |
