| Abstract: |
We identified a large expanding shell in the southeastern extension of the Sgr B2 complex using a survey observation of the CMZ in SiO v = 0, J = 2–1 and H13CO+ J = 1–0 emission lines by the Nobeyama 45-m telescope. The shell has high brightness temperature ratio of TB(SiO) /TB(H13CO+) = 6–8 and wide velocity width of Δ V ≥ 70 km s-1. This structure was presumably originated by successive super novae or an extreme super nova exploded within 5 × 105 yrs. |
