| « Formation of massive black holes at high-z - Beyond the Eddington-limit? » |

Warren Massonneau |
| A numerous amount of quasars at high-redshift have been discovered throughout the past decade (Wu et al. 2015, Bañados et al. 2017). A common characteristic between these discoveries is that each quasar contains a black hole of approximately 10^9 solar masses. Such massive black holes at the early stages of the Universe (= 1 billion years) challenge the theories to black hole formation and growth and their co-evolution with their host galaxies. I will review the recent discoveries of these high-z quasars and talk about numerous theoretical models that could explain the high masses that we observe. I will also describe the core of my thesis which is the super-Eddington accretion, its model and the early results that I've found. |
