Astrochemistry On Galactic Scales
The increasing number of observations towards different environments in the Milky Way, as well as theoretical and experimental works, are improving our knowledge of the astrochemical processes in the interstellar medium (ISM).
In this chapter we report some of the main projects to study the chemical complexity and isotopic ratios across the Galaxy.
High-sensitivity spectral surveys covering broad bandwidths towards Galactic Center molecular clouds (e.g. G+0.693-0.027) and star-forming regions (e.g. the hot core G31.41+0.31) are revealing very rich astrochemical reservoirs, which include molecules of prebiotic interest.
At the same time, isotopic ratios (e.g. 12C/13C and 14N/15N) can give important information on the Galactic chemical evolution, as well as on chemical local processes due to the physical conditions of the molecular clouds.
We also highlight the role of cosmic rays as a key agent affecting the interstellar chemistry described above.
