6. CO equivalent width: measuring stellar continuum ‘STARS’ stellar cluster models W CO6-3 ~ 4.5Å & W CO2-0 ~ 12Å adapted from Oliva et al. 1995 can correct for dilution & estimate stellar continuum

7. Brγ equivalent width - correct Brγ for AGN contribution (e.g. NLR, jet) through morphology & kinematics - ratio to stellar continuum Star Formation Diagnostics radio continuum (supernova rate) - resolved continuum with low T B probably star formation - correct flux for unresolved point source associated with AGN, and also for any jet contribution - estimate supernova rate mass-to-light ratio - use spatially resolved kinematics (V rot & σ) to estimate dynamical mass - correct L K for non-stellar continuum - gives upper limit to M/L K for most recent star formation Carilli et al.

10. nuclear stellar continuum resolved in all cases: no distinct & significant compact component on scales smaller than this age is 5-300 Myr but typically no longer active Star Formation Size & Age Cid Fernandes 04:central ~200pc of 79 nearby Seyfert 2s; 1/3-1/2 have experienced significant star formation in last few hundred Myr Kauffmann 03:central few kpc of 22600 AGN in SDSS; a significant fraction have experienced star formation in the recent (~Gyr) past

11. starburst luminosity is a few percent of AGN on scales <10pc, but comparable to AGN on kpc scales Stellar vs AGN Luminosity

12. Stellar Bolometric Luminosity Eddington limited starbursts in central ~10 pc M51 star clusters or Arp 220 (Scoville 03) radiatively supported starburst models (Thompson et al. 05) note: 500L sun /M sun ~ 10 13 L sun /kpc 2 for Σ=2×10 4 M sun /pc 2

13. Eddington limited starburst implies short star formation timescale – perhaps why we don’t see current activity stellar bolometric luminosity

14. Starburst – AGN connection best estimate of time since most recent star forming episode began Delay of close to100 Myr between starburst & AGN activity roughly AGN luminosity Eddington ratio

15. Summary adaptive optics integral field spectroscopy of mostly type 1 AGN, with spatial resolution to better than 10pc detailed morphologies & kinematics of molecular gas (e.g. NGC1068) and stars star formation:  recent star formation in nuclear disks  on 10pc scales, starbursts are Eddington limited & short lived  suggestion of a delay between starburst activity & AGN activity
