Abstract [en]

Since its launch in 2001, the Odin satellite has been observing the Galactic Centre Sgr A Complex (CND, +20 and +50 km s-1 Clouds) as well as the nearby star formation region, Sgr B2, a number of times. Observations have been made in the 118-119 GHz and 486-581 GHz bands. A limited mapping of the Sgr A Complex in the H162O line has been performed and new observations of the H182O line took place in 2006. In the 118-119 GHz band, a strong line of HC3N (J = 13 - 12) has been detected at a number of positions - sensitive upper limits have been obtained for the O2 (11 - 10) and the SiC (3Π2, J = 3 - 2) lines. Towards Sgr B2, submm observations have yielded absorption profles of H162O, H182O, H172O, NH3, and 15NH3.
