Can BLR line profile shape improve single-epoch black hole mass estimates?

Lizvette Villafaña, Tommaso Treu, Shu Wang +7

The virial coefficient (), which is meant to encapsulate broad-line region (BLR) geometry and kinematics, remains one of the largest sources of systematic uncertainty in black h…

A Phenomenological Study of the Accretion Disk in the Super-Eddington AGN I Zw 1

Farin Drewes, Roberta Vieliute, Juan V. Hernández Santisteban +11

The structure of the accretion disk in AGN is still an unsolved question, especially how it may change with Eddington ratio. Here we examine the accretion disk in the super-Eddingt…
