-The primary objective of the Cosmic polycyclic aromatic hydrocarbon (PAH) portal is to gather experimental data
+The main part of the activities are related to laboratory astrophysics in order to provide molecular data on **polycyclic aromatic hydrocarbons (PAHs)** and related species **of astrophysical interest**, as well as tools to analyze astronomical data.
-in order to:
+More specifically, we cover the following topics:
+* **Spectroscopy**
+- Evolution of infrared spectra with temperature. Simulations of the astronomical Aromatic IR Bands.
+- UV/visible spectroscopy. Link with the interstellar extinction curve.
+* **Photophysics in isolated environments**
+- UV-VUV photodissociation and photoionization.
+- Competition with radiative cooling.
+- Model of the evolution of PAHs in astrophysical environments.
+* **Mass spectrometry analysis**
+- Characterization of the molecular content of cosmic dust analogues and meteoritic samples.
+-O **//These activities were supported by the Nanocosmos ERC Synergy project (G.A. 610256) and CNES (ID 5830).//** 8-O
-- 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.
