The quasar 3C 273 has been observed with infrared spectroastrometry (SA) on broad Pa$\alpha$ line and optical reverberation mapping (RM) on broad H$\beta$ line. SA delivers information about the angular size and structure of the Pa$\alpha$…
The broadening of atomic emission lines by high-velocity motion of gas near accreting supermassive black holes is an observational hallmark of quasars. Observations of broad emission lines could potentially constrain the mechanism for…
