Updated 6/2/2025: Registration is no longer open, but you can access materials and recordings on the JWebbinars page a week or two after the event.

The NASA Ames Polycyclic Aromatic Hydrocarbon Infrared Spectroscopic Database (PAHdb) provides a from-the-ground-up means to analyze and interpret the PAH component in JWST observations. It offers the spectroscopic data (experimental and theoretical) of PAHs, advanced molecular excitation/emission models, ready-to-use software tools, and the comprehensive documentation needed for astrophysical/chemical modeling or for doing direct spectral fitting. This JWebbinar will be held on Wednesday, June 4^th and will provide: 

1. A demonstration of the PAHdb website (www.astrochemistry.org/pahdb): how to search the database content, utilize its online tools for simple analyses, and download data; 
2. An extensive follow-along demonstration of how to use the PAHdb Python suite of models and tools to analyze and interpret JWST observations; and 
3. A demonstration of how to use the lite version of the Python suite, dubbed pyPAHdb.

Ample opportunity will be given for participants to ask questions, discuss PAH-related topics, and provide input on the next steps for PAHdb.

Participants are required to register by May 30. Visit the JWebbinar webpage for information on the entire series of data analysis webinars.
