272-375GHz obs. toward SgrA*'s circumnuclear disk

Our data comprise eight individual pointings, with significant SiO (8_7_-7_6_) and SO (7-6) emission detected toward 98 positions within these pointings. Additionally, we identify H2CS (9_1,9_-8_1,8_), OCS (25-24), and CH_3_OH (2_1,1_-2_0,2_) toward a smaller subset of positions.

By using the observed peak line flux density, together with a Bayesian inference technique informed by radiative transfer models, we systematically recover the physical gas conditions toward each of these positions. We estimate that the bulk of the surveyed gas has temperature T_kin_<500K and density n_H_<~10^6^cm^-3^, consistent with previous studies of similar positions as traced by HCN clumps. However, we identify an uncharacteristically hot (T_kin_~600K) and dense (n_H_~10^6^cm^-3^) source in the Northeastern Arm.
