PublicaciónMicrolensing of the broad emission lines in 27 gravitationally lensed quasars. Broad line region structure and kinematics
Aims: We aim to study the structure and kinematics of the broad line region (BLR) of a sample of 27 gravitationally lensed quasars with up to five different...

PublicaciónPrimary Black Hole Spin in OJ 287 as Determined by the General Relativity Centenary Flare
OJ 287 is a quasi-periodic quasar with roughly 12 year optical cycles. It displays prominent outbursts that are predictable in a binary black hole model. The...

PublicaciónProbing 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...
