Presentation Transcript

  1. Millimeter interferometric investigations of the energy sources of nearby ULIRGs Masa Imanishi （NAO Japan）

  2. NLR ULIRGs: powerful energy sources hidden behind dust Obscured by torus-shaped dust Buried AGNs

  3. XDRs and PDRs(starbursts) are distinguishable from mm line ratios pure AGN HCN/HCO+ starburst HCN/CO Buried AGNs (=X-ray source) produce XDRs

  4. ULIRGs with buried AGNs Pure AGN ULIRGs without buried AGNs Starburst

  5. The AGN-nuclear starburst connections in Seyfert 1 and 2 galaxies Masa Imanishi （NAO Japan）

  6. Sy1 Sy2 Nuclear stabursts in a dusty torus Dust torus is rich in molecular gas Nuclear starbursts may occur 3.3um PAH 3.3um PAH PAH PAH = starburst tracer

  7. L(3.3 PAH) = nuclear starburst Nuclear N-band, radio core = AGN power nuclear starburst luminosity : Sy1s = Sy2s L(nuclear starburst) and L(AGN): correlate Imanishi 2003 ApJ 599 918 Imanishi and Wada 2004 ApJ 617 214
