[Okc-wp4] EO meeting Thu Mar 12 @ 13:15 at Room A5:1003

[Andre Schneider]

Dear colleagues,


our next EO meeting will take place this Thursday Mar 12 at 13:15.

The meeting will take place in Room A5:1003.
This is the "Room with a View" in the 5th floor.

This week Quentin Pognan (Stockholm University) will present

Title: Searching for Super-Eddington AGN

Abstract:
Accretion onto black holes at rates above the Eddington limit has long been discussed in the context of supermassive black hole (SMBH) formation and evolution, providing a possible explanation for the presence of massive quasars at high redshifts (z >~ 7), as well as having implications for SMBH growth at later epochs.
However, it is currently unclear whether such 'super-Eddington' accretion occurs in SMBHs at all, how common it is, or whether every SMBH may experience it. In this talk, I will present the work done to investigate the observational consequences of a simplistic model for super-Eddington accretion flows -- an optically thick, geometrically thin accretion disc (AD) where the inner-most parts experience severe photon-trapping, which is enhanced with increased accretion rate.


See you there!
