The most rapidly growing black holes: Narrow Line Seyfert 1s across cosmic time

要旨

Narrow Line Seyfert 1s (NLS1) are the lowest mass, highest mass accretion rate Active Galactic Nuclei (AGN) in the local Universe, with black hole masses of 1-10 million x Msun, accreting at the Eddington limit or beyond. These properties are similar to those expected for the majority of the first quasars in the early Universe, so I will show how understanding the accretion flow in these local NLS1 can guide our predictions for what we can see of the cosmic dawn, at z greater than 6-7.
