Logarithm of the integrated intensity ratio. Top: log (T(SiO)dv/T(HCO + )dv) in the velocity range from 30 to 130 kms-1. The contours correspond to the HCO+ emission at 3σ and 30σ. We can identify clearly regions where either the SiO (e.g. in the 1.3 Complex and in the M+3.2+0.3 cloud) or HCO+ (e.g. towards Sgr A region) dominate. Bottom: log (T(SiO)dv/T(H13CO + )dv) in the velocity range from  −110 to  −50 kms-1. The contours correspond to the SiO emission at 3σ and 30σ. In this velocity range, we can see the enhacement of the SiO toward the M − 3.8+0.9 cloud.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
