Limits on the Spatial Extent of AGN Measured with the Fine Guidance Sensors of the HST
Richard N. Hook, Ethan J. Schreier, George Miley
The optical structure of several AGN has been studied using the Fine Guidance Sensors (FGS) on the Hubble Space Telescope (HST). The FGSs are interferometric devices which can reso…
