概要 | We have performed unbiased line surveys at the 3 mm band toward the Galactic circumnuclear disk (CND) and Sgr A* using the NRO 45 m radio telescope. We have obtained three wide-band spectra that cover the frequency range from 81.3 GHz to 115.8 GHz, detecting 50 lines from 30 species. Based on the line intensities, we classified the detected lines into three categories: the CND, GMC, HBD types. We suggest that the large molecules have been destroyed in the vicinity of the nucleus by high energy photons and/or cosmic ray particles from the nucleus. |
