Hard to see.
How can you do it?
HST (Bahcall, others)
Near Infrared (eg., McLeod et al. 1996)
AO sort of.
What are their properties?
Are they related in any way
to the activity?
Very little known before advent of HST, AO, and large
Still a challenging type of
Initially thought (based on Seyfert galaxies and radio
galaxies) that radio properties were related to host type.
Seems to have been a selection effect.
