## COSMIC PAH portal

### Description

Polycyclic aromatic hydrocarbons (PAHs) and related molecular species (e.g. fullerenes) are key species in astrophysical environments. The primary objective of the Cosmic PAH portal is to ease access to databases and tools in order to:

• Identify these species in astrophysical environments and in extraterrestrial samples.
• Understand their formation pathways and their link with related molecular species such as carbon clusters and fullerenes.
• Model their evolution in astrophysical environments and their impact on the physical and chemical conditions.
• Molecular databases developed by the team, both theoretical and experimental.
• Simulated spectra databases for PAH infrared emission in various astrophysical environments.
• Spectral analysis tools to analyze in a consistent way spectra from experiments. theoretical calculations, and astrophysical observations.
• Tools to model spectra in astrophysical environments using experimental and theoretical data.
