Interstellar ices in the lab: the importance of being water

Solid water is a very abundant material. Indeed, it is believed to be the most abundant condensed material in the Universe, thanks to its propensity to remain as a deposit on interstellar dust particles in dense clouds.

In this talk, I shall present how we are able to grow realistic water ice analogues in the laboratory, to choose their structure, to model their morphology, and to use them as a substrate fit for the surface chemistry leading to molecular complexity in space. Water ice will turn out to be a unique and rich case study for laboratory simulations of ices at low temperatures in an astrophysical environment.
