Millimeter interferometric investigations of the energy sources of nearby ULIRGs Masa Imanishi (NAO Japan)
NLR ULIRGs: powerful energy sources hidden behind dust Obscured by torus-shaped dust Buried AGNs
XDRs and PDRs(starbursts) are distinguishable from mm line ratios pure AGN HCN/HCO+ starburst HCN/CO Buried AGNs (=X-ray source) produce XDRs
ULIRGs with buried AGNs Pure AGN ULIRGs without buried AGNs Starburst
