Welcome to the ORION-B project

Molecular lines and line ratios are commonly used to infer properties of Galactic and extra-galactic star forming regions. The new generation of (sub-)millimeter receivers turns every observation nearly into a line survey. To fully exploit this technical advance in extra-galactic studies requires detailed bench-marking of available line diagnostics. We aim to develop the Orion B Giant Molecular Cloud as a local template for interpreting Galactic and extra-galactic molecular line observations.
