Interstellar PAHs: separating the neutrals from the ions — This project will use JWST/MIRI and NIRSpec to capture the first-ever spectrum of purely neutral PAHs (Polycyclic Aromatic Hydrocarbons) in space by observing nebulae surrounding cool stars that produce no ionizing radiation. This provides the missing piece to separate neutral from charged PAHs in all cosmic environments.
