    Individual Estimates of the Virial Factor in 10 Quasars: Implications on the Kinematics of the Broad-line Region
    Assuming a gravitational origin for the Fe iiiλλ2039-2113 redshift and using microlensing based estimates of the size of the region emitting this feature, we...

    Probing the roles of orientation and multiscale gas distributions in shaping the obscuration of active galactic nuclei through cosmic time
    The origin of obscuration in active galactic nuclei (AGNs) is still an open debate. In particular, it is unclear what drives the relative contributions to the...
