DESCRIPTION:Speakers: Ric Davies (MPE)\n\n\n\n\n\nThe broad line region an
 d near-infrared hot dust continuum trace two of the key structures on sub-
 parsec scales around AGN\, and understanding them provides insights into h
 ow black holes and their host galaxies evolve. I will introduce the interf
 erometric and spectro-astrometric techniques used in our GRAVITY-AGN progr
 amme\, and summarize the main results from spatially resolving these struc
 tures on sub-parsec scales in local AGN as well as at z=2-4. I will descri
 be our observations of rotating versus outflowing BLRs\; report on our dyn
 amical black hole mass measurements at these epochs which point towards su
 per-Eddington accretion\; and compare our masses to those derived from sca
 ling relations. Results from these first few QSOs hold great promise for o
 ur on-going large programme to observe a sample of 20 QSOs at z~2.\n\n\n\n
