Carbon macromolecules in the cycle of interstellar matter: observations andlaboratory experiments

TL;DR

This paper discusses how observations and laboratory experiments support the role of carbon macromolecules as intermediates in the cycle of interstellar matter, linking small molecules to dust structures.

Contribution

It provides integrated observational and experimental evidence for the role of carbon macromolecules in interstellar matter cycles, highlighting their intermediary function.

Findings

Observations confirm presence of carbon macromolecules in space.

Laboratory experiments replicate interstellar conditions.

Supports the intermediary role of macromolecules in dust formation.

Abstract

Carbon macromolecules are intermediates between small gas-phase species and larger dust structures. I illustrate how observations and dedicated laboratory experiments support this picture.
