Gaia and MUSE provide amazing data for both the Milky Way and external
galaxies. The data reflect huge selection effects and to overcome these we
need sophisticated chemo-dynamical models that can be `observed' with the
same biases. It's vain to suppose we can infer how galaxies formed and how they
work as machines until we have constructed credible chemo-dynamical models.

We can observe the Universe in exquisite detail by careful study of the wavelengths of light that arrive at Earth. However to interpret these signals requires laboratory data, much of it associated with spectroscopy and the behaviour of molecules. In hotter environments such the atmospheres of brown dwarfs, cool stars and most observed exoplanets, as well non-LTE environments such cometary...
