 note = {SPICA Science Conference from Exoplanets to Distant Galaxies: SPICA's New Window on the Cool Universe (June 18-21, 2013. Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, Japan, Here we show the results of our ALMA cycle 0 observation toward the nearby type-1 Seyfert nucleus in NGC 1097. We observed some typical dense gas tracers such as HCN (J=4-3) and HCO+ (J=4-3). We find that the HCN (J=4- 3)/HCO+ (J=4-3) and HCN (J=4-3)/CS (J=7-6) integrated intensity ratios are enhanced in AGNs including NGC 1097 compared to nearby starburst galaxies and Galactic star forming regions. Multi-line/transition analysis of HCN and HCO+ emissions reveal that these lines are emitted from dense (10(exp 4.5) less than or equal to nH2 [cm(exp −3)] less than or equal to 10(exp 6) and hot (70 less than or equal to T(sub kin) [K] less than or equal to 550) regions, and that HCN to HCO+ abundance ratio is high (4-20). We introduce a “high-temperature chemistry” to explain the observed properties. Finally, we briefly discuss the possible future studies with ALMA and SPICA on AGN science., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730027045, レポート番号: JAXA-SP-17-010E},
