Disks and Jets:

extraction of excess angular moment, efficiency of formation

exact nature of acceleration of the jet is unclear

jet rotation and precession?

peculiar velocity fields, bow shocks

Black Hole in Galactic Nuclei

Measuring the BH mass:• Star dynamics• Gas dynamics• (size of BLR, line width,

reverbaration mapping)
